Women such as Ada Lovelace, the English mathematician often recognized as the first programmer in history, and Katherine Johnson, whose calculations helped ensure safe NASA space missions, have played a critical role in advancing computer science. More recently, leaders such as YouTube CEO Susan Wojcicki and IBM CEO Ginni Rometty continue to drive technological innovation.
The achievements of these and other women throughout history have pushed the boundaries of computer science. But significant disparities remain between men and women in the field. Paying homage to women who have made significant contributions to computer science is a critical first step in closing that gap. Understanding the leadership roles available to women in computer science and how to reach them are also crucial building blocks for creating a more equitable workforce.
A history of women in computer science
Women’s contributions to computer science and technology include developing the first computer program, inventing computational methods, and advancing space technology. Yet, women’s contributions to science and technology have largely been written out of history.
Consider these four pioneering women in computer science: Ada Lovelace, Katherine Johnson, Rear Admiral Grace Hopper, and Margaret Hamilton.
Early in her career, Ada Lovelace, also known as Augusta Ada Lovelace (A.A.L.), worked alongside mathematician, inventor, and recognized father of computing Charles Babbage, who created the difference engine, a machine that performed mathematical calculations. She then made plans for the analytical engine, a device to handle more complex calculations. In 1843, she published a paper under the initials A.A.L. that described a method for repeating a series of instructions. The process, known as looping, is used in modern-day computer programs.
As depicted in the film Hidden Figures, Katherine Johnson’s biography includes contributions to elevating NASA programs in the early 1960s. Her calculations made orbiting around Earth and landing on the moon possible for humans. According to NASA, her calculations also helped “sync Project Apollo’s Lunar Module with the lunar-orbiting Command and Service Module,” and she co-authored 25 research reports. She received the Presidential Medal of Freedom, the highest civilian honor in the U.S., in 2015 at age 97.
Rear Admiral Grace Hopper
Grace Hopper, considered among the most consequential computer scientists of all time, developed one of the first compilers, which translate one programming language into another. It paved the way for COBOL, a language still in use 60 years later. Her inventions also laid the groundwork for future computer advancements including code optimization, which allows code to work more efficiently or with fewer resources. She’s also known for helping popularize the term “computer bug” while working as a programmer on the Harvard Mark II Aiken Relay Calculator, a room-sized computer developed after World War II. The bug, a real-life moth, caused a computer flaw before it was extracted.
There’s a strong chance that astronauts Neil Armstrong, Buzz Aldrin, and Michael Collins would have aborted the July 20, 1969, moon landing were it not for Margaret Hamilton’s contributions to the Apollo space program. She wrote the software code for Apollo 11’s onboard guidance and navigation system, which was then adopted and adapted for remaining Apollo missions, the Space Shuttle program, and more. She is also noted for coining the term “software engineering” for her software development approach, which included rigorous testing. Hamilton was honored with the NASA Exceptional Space Act Award in 2003 and received the Medal of Freedom in 2016.
Other important women in computer science history
Above are just a few of the women who have impacted the history of computer science. Many more women have contributed to the field, including:
- Frances E. Allen: Renowned for her work in compiler organization and optimization algorithms and her achievement as the first female IBM fellow
- Dame Stephanie “Steve” Shirley: Celebrated for building a $3 billion tech company with an all-female, work-from-home staff in the 1960s, and for her company’s programming of the black box for the Concorde, the first supersonic commercial airplane
- Radia Perlman: Invented the spanning tree protocol (STP), an algorithm essential to the internet, and then TRILL, which corrects STP’s limitations

Exploring the gender gap
Women have long been underrepresented in the computer science industry, and a notable shortage of women in the field remains today. Here are key statistics that highlight the gender gap in computer science.
- While the percentage of women in the science and engineering labor force grew from 23% in 1993 to 29% in 2017, according to data from the National Science Foundation, the number of women in computer and mathematical science roles declined in the same period from 31% down to 27% due to stronger growth among male counterparts.
- According to Deloitte, women make up 47% of the workforce, yet only 27% of technology industry conference speakers are women.
- Closing the gender gap will remain an uphill battle, and this is reflected in the gap between male and female computer science authors. A 2018 study of 2.87 million computer science research papers published by arXiv found that “under our most optimistic projection models, gender parity is forecast to be reached by 2100.”
How can we close this gap? Introducing girls to computer science in early education is key. Support networks and role models who encourage the pursuit of technology studies — including parents, teachers, and friends — can inspire young women to pursue computer science careers. It’s also important for girls to have visible role models in entertainment and media.
Organizations like Girls Who Code and ProjectCSGirls partner with schools to establish tech programs and clubs for female students, while also seeking to break down historical and institutional boundaries such as racial bias and discrimination in technology fields. Universities are also seeking to make computer science courses more appealing and accessible to women.
The industry has a significant role to play as well. Building an inclusive culture for women to advance in their careers can play a crucial role in ensuring women remain in the field. Women leave computer science roles at a much higher rate than men due to workplace conditions, barriers to creative roles, and a lack of advancement opportunities, according to the National Center for Women and Information Technology. In this respect, companies committed to diversity and inclusion initiatives are in a great position to make a difference and bridge the gender gap in computer science.
Roles for women in computer science
Women fill a variety of roles in computer science. Women in leadership positions such as chief technology officer and engineering manager are well-situated to mentor other women interested in entering the computer science field. They typically have many years of experience and are often responsible for hiring new talent.
However, women in entry-level and midcareer computer science positions such as software developer, computer programmer, mechanical engineer, and computer support specialist can also play a key role in mentoring the next generation of women in computer science.
These are some examples of the roles available to women interested in pursuing computer science careers.
The primary focus of a software developer is to develop, design, and implement computer programs and applications. Specific responsibilities vary depending on the type of hardware and business focus of their employer. Some developers create the software that runs devices and networks.
