Celebrating Women's History Month: Women Who Transformed Manufacturing Over the Last 125 Years

It’s March, and in honor of Women’s History Month, we’re taking a look at the women who helped shape manufacturing over the last 125 years.

Here at TeamSense, it’s a history that is close to home. Our CEO, Sheila Stafford, is part of a long line of women who have helped push this industry forward, and so are many of the women in the manufacturing communities we serve every day. From the plant floor to operations leadership to engineering and workforce management, women have helped move manufacturing forward for a long time, in roles both visible and overlooked.

That matters because manufacturing history usually gets told through machines, plants, and output. But industries do not improve on equipment alone. They improve because people find better ways to run work, solve problems, scale production, and support the workforce behind it. Some of those people became well-known. Many did not.

That is part of what we wanted to recognize here. This list highlights some of the women whose work changed labor conditions, production systems, materials, computing, and industrial leadership. But it also stands in for the many others whose names never made it into the broader record, even though their impact was real and lasting.

125 Years of Women Reshaping the Factory Floor

Manufacturing has been a backbone of the American economy for well over a century. It has generated trillions in output, employed millions of people across the country, and helped shape the broader story of industrial progress, from early assembly lines to semiconductor fabrication. But even as the industry evolved, women have remained underrepresented in manufacturing compared with the workforce overall.

That gap is still visible today. Women make up about 47 percent of the U.S. workforce, but hold around 30 percent of the manufacturing jobs available in the US. Also, roughly one in four manufacturing management roles is held by a woman. That points to real progress, but it also shows how far the industry still has to go.

The history in this piece spans about 125 years, from the rise of industrial engineering at the turn of the 20th century to today’s semiconductor and aerospace sectors. Across that time, women helped shape manufacturing through labor reform, wartime production, materials science, enterprise leadership, and advanced manufacturing. Their work changed how goods were made, how factories were managed, and how operations ran at scale.

That story comes into focus through 12 figures and one cultural symbol that helps connect the eras: Mary Harris Jones, Lillian Moller Gilbreth, Rosie the Riveter, Elsie MacGill, Stephanie Kwolek, Margaret H. Wright, Ursula Burns, Mary Barra, Ginni Rometty, Lisa Su, Gwynne Shotwell, and Judy Marks.

Rosie the Riveter belongs here a little differently than the others. Rosie is not one executive, engineer, or inventor. She is a symbol of wartime labor and a reminder of the moment women were no longer seen as just temporary help, but as essential to production itself.

1900-1930s: Labor Reform and the Science of Industrial Work

The early 20th century changed manufacturing in a big way. Small workshops gave way to larger factories, production became more standardized, and industrial engineering started to take shape as a real discipline. That shift created new opportunities for scale, but it also raised harder questions about efficiency, working conditions, and worker welfare.

Women had been part of American manufacturing long before 1900, but they were concentrated in lower-wage, lower-authority roles. Edith Abbott’s early work on women in industry helped document the long-standing role women played in industrial labor. In this period, two women shaped manufacturing from very different angles: one through the study of work itself, and the other through labor organizing.

Lillian Moller Gilbreth (1878-1972): Engineering the Human Factor

Lillian Moller Gilbreth helped build the field of time-and-motion study alongside Frank Gilbreth. Their work focused on breaking jobs down into individual movements so tasks could be done more efficiently, with less wasted motion and less fatigue.

One of the best-known tools associated with that work was the therblig system, which classified 17 basic motions involved in manual work. That gave manufacturers a way to study jobs more closely and redesign tasks, tools, and equipment around how work was actually being performed.

What set Gilbreth apart was her focus on the human side of efficiency. She helped bring psychology into scientific management and argued that fatigue, behavior, and worker capability all mattered in how work should be designed. After Frank Gilbreth’s death in 1924, she continued the work on her own. In 1935, she became a professor in Purdue’s School of Mechanical Engineering, where Purdue says she was its first female engineering professor. Later sources, including PBS and ASME, also describe her as the first woman elected to the National Academy of Engineering.

Mary Harris Jones (1837-1930): Organizing the Factory Floor

Mary Harris Jones, better known as Mother Jones, approached industrial work from a different direction. She was a labor organizer who became especially prominent through her work with miners, while also fighting child labor and advocating for workers facing dangerous conditions and weak legal protections.

The conditions she pushed against were part of the reality of early industrial labor: unsafe equipment, exhausting hours, and widespread exploitation, including child labor. Her organizing helped bring national attention to the human cost of industrial growth and contributed to the broader labor movement that pushed for stronger protections for workers.

Where Gilbreth worked to improve how labor was performed, Jones pushed to change the conditions under which that labor existed. One approach was technical. The other was organizational. Together, they reflect two different ways women helped reshape manufacturing in the early 20th century.

1940s: Wartime Production and the Industrial Scale-Up

World War II created the most concentrated production challenge in American history. Plants shifted from consumer goods to aircraft, munitions, vehicles, and equipment. With millions of men entering military service, factories faced a direct constraint: they could not meet output targets without rebuilding their workforces from scratch

Between 1940 and 1945, the number of women in the workforce grew by 50%. By the end of the war, women comprised 36.1% of the total labor force. In many manufacturing sectors, the numbers pulled back after demobilization. But the wartime years left a clear operational record of women staffing and running industrial production under intense schedule pressure.

Rosie the Riveter: Production Recruitment and the Manufacturing Labor Shift

The Department of Labor estimates that between 5 million and 7 million women held war industry jobs during World War II, and another Department of Labor statement says more than 6 million women joined the workforce building airplanes, tanks, guns, and warships.

Rosie the Riveter became the public face of that shift. The Department of Labor explains that the government used Rosie’s popularity in a recruiting campaign that brought millions of women into the workforce, especially in work long seen as men’s work. 

Rosie the Riveter was the symbol, but the real story was what was happening inside manufacturing plants. As wartime production ramped up, women were recruited into factory jobs at scale to help meet demand and keep production schedules on track.

That meant more than filling open roles. Plants had to train new workers fast, maintain quality, manage safety, and keep volume high, all at the same time. Women stepped into industrial jobs in huge numbers and became a critical part of keeping wartime manufacturing running.

That is what makes Rosie important in this story. She represents more than recruitment. She represents a turning point in how women were seen in manufacturing: not as temporary help on the margins, but as essential to production itself. And while Rosie became the cultural symbol of that shift, the wartime record also includes real women who were leading manufacturing and engineering work at the highest levels.

Elsie MacGill (1905-1980): Chief Aeronautical Engineer and Wartime Production Leader

Elsie MacGill was one of the clearest examples of women moving beyond wartime factory labor into technical and production leadership. In 1929, she became the first woman to earn a master’s degree in aeronautical engineering from the University of Michigan, and she went on to build her career in aircraft engineering soon after.

At Canadian Car and Foundry, MacGill became Chief Aeronautical Engineer on the Canadian production of the Hawker Hurricane fighter aircraft. In that role, she was not just overseeing drawings or working in the background. She was leading the engineering side of a major wartime manufacturing effort, helping manage aircraft production at scale during a period when output, speed, and reliability all mattered at once. Veterans Affairs Canada and other historical sources credit the company with producing 1,451 Hurricanes between 1939 and 1943, roughly one out of every ten built worldwide.

Her contribution was practical as well as managerial. MacGill helped adapt the Hurricane for Canadian winter conditions by supporting modifications such as de-icing features and ski landing gear, which made the aircraft more usable in cold-weather environments. That matters because it shows her role was not limited to supervising production. She was also solving engineering problems tied directly to real operating conditions.

She became widely known during the war as the “Queen of the Hurricanes,” a nickname reinforced by wartime media coverage and a comic-book profile published in 1942. But the title only hints at the scale of what she represented. MacGill stood at the top of a highly visible wartime production program at a moment when women were still treated as exceptions in engineering leadership. Her career helped show that women were not only capable of filling urgent labor gaps on the factory floor, but of leading complex manufacturing and engineering work at the highest levels.

That is the bridge this era created. Rosie represents mass labor entry. MacGill represents production leadership, planning, and engineering control. Together they show how wartime scale moved women from being seen as labor substitutes to being recognized as necessary to industrial execution.

1950s-1970s: Engineering Innovation and Materials Manufacturing

After the war, manufacturing shifted rather than slowed. Synthetic polymers and advanced fibers moved from research labs into production lines. Chemical and materials companies such as DuPont, Dow, and 3M expanded into research-driven manufacturing, with development cycles that had to end in repeatable, scalable output.

Women researchers in corporate laboratories remained relatively few during this era, and representation in scientific and engineering research roles was extremely limited. The work still advanced through whoever could handle the slow discipline of experimentation, process development, and documentation required before a material could ever run as product.

Stephanie Kwolek (1923-2014): Inventing the Material That Changed Manufacturing

Stephanie Kwolek spent more than 40 years as a chemist at DuPont, where her work helped change what modern manufacturing could do. In the mid-1960s, while researching new synthetic fibers, she discovered the polymer solution that would eventually become Kevlar.

That discovery mattered not just because the material was strong, but because it opened the door to entirely new performance standards across multiple industries. Kevlar is known for being extremely strong relative to its weight, and DuPont introduced it commercially in 1971. The gap between discovery and commercialization is part of the story too. It shows how much development, testing, and process engineering it takes to turn a lab result into a material that can be manufactured reliably at scale.

Over time, Kevlar moved into a wide range of industrial and consumer applications, including body armor, protective gear, automotive components, and aerospace uses. That reach is part of what makes Kwolek’s contribution so significant. She did not just invent a successful product. She helped create a material platform that changed how manufacturers thought about strength, weight, and durability.

Kwolek held multiple patents over the course of her career and was inducted into the National Inventors Hall of Fame in 1995. Her work is a good example of how one breakthrough in materials science can ripple outward for decades, shaping products, safety standards, and manufacturing possibilities far beyond the lab where it started.

Margaret H. Wright (1944– ): Optimization and the Computational Side of Modern Manufacturing

By the late 20th century, manufacturing was becoming a much more computational business. Running complex operations now required more than physical production capacity alone. It also required better modeling, better optimization, and better ways to make decisions across large systems.

Margaret H. Wright was part of that shift. Her work in numerical optimization and scientific computing helped advance the mathematical methods used to solve large, real-world industrial problems. While her contributions were not tied to a single factory floor or product line, they reflect something essential about this era: manufacturing increasingly depended on advanced computation behind the scenes.

Wright worked at AT&T Bell Labs before moving into academic leadership at NYU’s Courant Institute. Across that career, she stood at the intersection of mathematics, computing, and industry, helping shape the tools that made large-scale technical decision-making more possible.

If Gilbreth helped define efficient motion on the floor, Wright’s field helped define efficient decisions in more complex systems. Modern manufacturing depends on models that are mostly invisible to the line worker but decisive to throughput, process design, and resource allocation. By this point in the timeline, manufacturing had clearly moved beyond the line into the lab and the model.

That is why she belongs in this conversation. Manufacturing progress in the late 20th century was not only about new materials or faster machines. It was also about better systems for solving hard problems, and Wright’s work represents that quieter but increasingly important side of industrial change.

1980s-2000s: Enterprise Leadership in Automotive and Global Manufacturing

By the late 20th century, manufacturing leaders were being asked to manage pressure from every direction. Companies were consolidating plants, restructuring supply chains, chasing cost targets, and trying to protect quality and delivery at the same time. In that kind of environment, leaders who understood operations from the inside brought a different kind of credibility than those who came up through finance or marketing alone.

This was also the period when women began breaking into vice president and C-suite roles at major manufacturing companies. Many of the women who reached those positions came up through engineering, plant operations, and supply chain leadership. That matters because it shaped how they led. They were not managing manufacturing from a distance. They understood what decisions looked like when they hit the plant floor, the production schedule, and the workforce responsible for keeping operations moving.

Mary Barra (1961– ): General Motors and the Restructuring of Automotive Manufacturing

Mary Barra joined General Motors as a co-op student at 18 and worked her way through manufacturing, engineering, and human resources before becoming CEO in 2014. Because she came up through the business instead of around it, she brought a direct understanding of how manufacturing decisions play out when volume, quality, labor, and cost are all under pressure at once.

During her time as CEO, GM committed $35 billion to electric and autonomous vehicle technologies, pushed toward carbon neutrality across global operations by 2040, and built out the Ultium battery platform for its next generation of EVs.

From a manufacturing standpoint, those were not abstract strategy moves. They meant plant retooling, supplier changes, workforce retraining, and the challenge of bringing a new platform online while existing operations still had to hit production goals. Barra’s leadership reflects what this era demanded from manufacturing executives: not just vision, but the ability to manage large-scale operational change without stopping the business in the process.

Ursula Burns (1958– ): Xerox and Operational Transformation at Scale

Ursula Burns joined Xerox in 1980 as a mechanical engineering summer intern and spent the next three decades moving through manufacturing, product development, and corporate operations before becoming president in 2007 and CEO in 2009. That path matters. She came up through the business itself, with firsthand experience in how product, supply chain, and production decisions affect the rest of the organization.

Burns led Xerox during a period when the company was shifting beyond its traditional hardware roots and expanding more deeply into business services. That kind of transition is not just a strategy slide. It changes what gets built in-house, what gets sourced, how service issues feed back into design and production, and how the workforce is retrained and redeployed along the way.

Her leadership also carried historic weight. Burns became the first Black woman to lead a Fortune 500 company, and the first woman to succeed another woman as CEO of a Fortune 500 company. But what makes her fit this story is not only the milestone. It is the kind of operational leadership her career represented: the ability to guide a large, established company through structural change while staying grounded in how the business actually runs.

Outside Xerox, Burns has also been a visible advocate for STEM education and workforce development. That matters in manufacturing because talent problems do not stay abstract for long. They show up as hiring gaps, overtime pressure, uneven coverage, and the strain that comes when companies cannot build or keep a stable skilled workforce.

Ginni Rometty (1957– ): IBM and the Digital Systems Behind Modern Manufacturing

By the 2000s, manufacturing leadership was no longer only about plants, parts, and production schedules. It was also about data, software, cybersecurity, and the systems companies used to run increasingly complex global operations. As manufacturers became more dependent on digital infrastructure, enterprise technology started to shape industrial performance in a more direct way.

Ginni Rometty’s career sits inside that shift. She joined IBM in 1981 and became the company’s first female CEO in 2012 after rising through engineering, services, sales, marketing, and strategy roles. During her tenure, IBM pushed further into hybrid cloud, AI, security, and quantum computing, all of which became increasingly important to large industrial companies trying to modernize operations and make better decisions across global systems.

What makes Rometty fit this story is not that she ran a factory. It is that she led one of the companies helping define the digital backbone modern manufacturers rely on. As industrial businesses took on more connected systems, more data, and more pressure to modernize without disrupting the core business, leadership like hers became part of the manufacturing story too.

She also became a symbol of enterprise leadership at scale. Rometty was the first woman to lead IBM, and her rise reflected a broader shift in who was beginning to shape major industrial and technology companies from the top. In an era when manufacturing was increasingly tied to enterprise software, analytics, and digital transformation, that kind of leadership mattered well beyond the tech sector itself.

2000s-Present: Semiconductor, Aerospace, and Advanced Manufacturing Leadership

Today, manufacturing leadership sits where engineering depth, supply chain discipline, and platform strategy meet. Semiconductors, intelligent equipment, connected products, and AI infrastructure all play a role in how industrial companies build, support, and improve what they make.

This era also expanded the definition of manufacturing itself. It is no longer just about what happens inside one plant. It is about fab ecosystems, electronics supply chains, software-enabled products, installed-base upgrades, and lifecycle service models that keep value going long after initial production.

That shift changed the leadership profile too. Success now depends not only on running production well, but on managing complexity across technology, suppliers, product platforms, and service over time.

Lisa Su (1969– ): AMD and Semiconductor Manufacturing at Scale

Lisa Su earned a Ph.D. in electrical engineering from MIT and became AMD’s president and CEO in October 2014. She stepped into the role at a difficult moment for the company, but under her leadership AMD rebuilt its position and became a much stronger force in high-performance and adaptive computing.

That turnaround mattered to manufacturing because semiconductors are not just a product category. They sit underneath data centers, consumer devices, embedded systems, industrial equipment, and AI infrastructure. As AMD expanded across those markets, Su’s strategy relied on deep engineering investment, product roadmap discipline, and close partnerships across the semiconductor manufacturing ecosystem.

By 2024, AMD reported record annual revenue of $25.8 billion, up from a much smaller base when Su became CEO. The company’s growth reflected more than a financial recovery. It showed how much execution matters in semiconductors, where product design, fabrication partnerships, packaging, supply chain coordination, and timing all have to work together.

Su has also become one of the most visible voices in the industry on the future of chips, AI, and supply chain resilience. In 2024, TIME named her CEO of the Year, recognizing both AMD’s turnaround and its expanding role in the next wave of computing infrastructure.

Gwynne Shotwell (1963– ): SpaceX and the Manufacturing of Reusable Rockets

Gwynne Shotwell joined SpaceX in 2002 and became president in 2008. She came in with an engineering background and helped lead the company through the kind of growth that goes far beyond product design. SpaceX was not just trying to build rockets. It was trying to build the capacity to manufacture, test, launch, recover, and fly them again at a pace the industry had not seen before.

That is what makes her relevant to this story. Reusability is not only an engineering win. It is a manufacturing and operations challenge. It depends on repeatable builds, tight process control, structured refurbishment, and supply chains strong enough to support quick turnaround without losing reliability.

Under Shotwell’s leadership, SpaceX helped prove that rockets could become part of a more repeatable production model instead of a one-time build-and-launch system. That changed more than launch economics. It changed what aerospace manufacturing could look like when engineering, operations, and production all move in sync.

Judy Marks (1963– ): Otis and Precision Industrial Manufacturing at Global Scale

Judy Marks joined Otis as president in 2017 and became CEO in June 2019, later leading the company through its 2020 spin from United Technologies into an independent public company. Before that, she held senior leadership roles at IBM, Lockheed Martin, and Siemens, including serving as CEO of Siemens USA and Dresser-Rand.

That background matters because Otis is not just a manufacturer. It is a company built around products with long operating lives, global installed bases, and constant service demands. Today, Otis maintains approximately 2.4 million customer units worldwide, and service represents about 60 percent of sales.

From a manufacturing standpoint, that changes the job. Elevators and escalators are not built once and forgotten. They are designed, manufactured, installed, maintained, and modernized over decades. Decisions made upstream in component design, supplier qualification, and production quality show up later in uptime, parts availability, service calls, and the workload carried by field teams.

That is what makes Marks fit this era. Her leadership sits at the intersection of manufacturing, installed-base service, and modernization at global scale. In practical terms, that means managing not just what gets built, but how well those products hold up over time and how effectively the business supports them long after they leave the factory.

What This History Says About Women in Manufacturing Today

Looking across these eras, the pattern is pretty clear. Women did not shape manufacturing from just one corner of the industry. They influenced it through labor advocacy, industrial engineering, production scaling, materials science, computational methods, and executive leadership. The work looked different from era to era, but the through line is hard to miss: women helped change how manufacturing operates.

That history matters, but it should not be confused with full representation in the present. Women accounted for 29.2 percent of U.S. manufacturing employment in 2021, which means their presence in the industry is significant, but still not proportional to their share of the broader workforce.

For plant leaders, operations teams, and HR, that is not just a cultural point. It is an operational one. The next chapter is not only about recognizing visible leaders after the fact. It is about building workplaces where more women can get hired, trained, developed, and moved into roles where their skills shape the future of the industry in real time, including smarter approaches to headcount vs skill coverage in manufacturing.

A Modern Extension of Operational Leadership

That is part of why this history still feels current. The women who changed manufacturing in earlier eras were often close to the work itself before they moved into broader leadership. They came out of engineering, labor, product development, operations, and systems. That pattern did not stop. It still shows up today, even if it is less likely to make a history book. Sheila Stafford’s career is one modern example of that.

Sheila Stafford: TeamSense and Workforce Visibility as an Operations Problem

Sheila Stafford built her career in manufacturing before becoming CEO of TeamSense. A manufacturing engineer by background, she worked in manufacturing leadership at Whirlpool and General Motors, where she saw firsthand how often production gets disrupted by communication gaps between HR, managers, and frontline employees. That experience became the foundation for TeamSense.

Her early time at GM also gave her a direct example of the kind of leadership this history is about. During her first assignment at Detroit Hamtramck Assembly, Mary Barra was the plant leader, and Stafford was part of the Cadillac DTS launch. Seeing a woman in plant leadership that early in her career mattered. It was real proof that the glass ceiling people assumed was there was already starting to crack.

She later co-founded TeamSense in 2020 after seeing how hard it still was for many plants to get fast, reliable visibility into workforce issues. In too many operations, call-offs still rely on “call a manager” processes, attendance problems, and shift changes still move through voicemails, spreadsheets, and last-minute workarounds. TeamSense was built to close that gap by giving frontline teams a simpler way to communicate with supervisors and HR.

That is what makes Stafford fit this story. Her work treats workforce communication as part of operational performance, not something separate from it. In manufacturing, labor issues do not stay contained inside HR. They show up in missed shifts, overtime pressure, shift coverage planning challenges, line coverage problems, and the scramble that happens when teams are trying to keep production on track without clear visibility into who is actually available to work.

In that sense, Stafford reflects a more modern version of the same pattern seen throughout this history: identifying a real operational problem up close, understanding how it affects day-to-day production, and building a better system around it.

From Factory Floors to the Future

Across every era in this story, the work has been concrete. It looked like motion studies that reduced fatigue without slowing output. It looked like labor organizing that pushed back on dangerous conditions and impossible hours. It looked like wartime engineering decisions that had to hold up under pressure, materials breakthroughs that took years to scale, and executive decisions that eventually became tooling plans, supplier qualifications, quality standards, and staffing models.

That is part of what connects these women across 125 years of manufacturing history. Their influence did not live only in titles or recognition. It showed up in how work was designed, how systems improved, how production scaled, and how companies adapted when the stakes got higher.

Women are still underrepresented in manufacturing, and the leadership gap remains wider than it should be. But the next era of manufacturing will need the same qualities that shaped the last one: technical depth, operational discipline, good judgment under pressure, and the ability to manage complexity over time. In semiconductors, aerospace, advanced materials, and autonomous systems, that work is already happening. So is the leadership behind it.
