Women in Computing

Recognizing women who have been instrumental in computing and data science

Profile photo for Ada Lovelace

Women have been fundamental to the growth of data science and computing. In fact, throughout the 19th and early 20th centuries, up to World War II, programming was predominantly done by women. Significant examples include the Harvard Computers, codebreaking at Bletchley Park and engineering at NASA, and the names of Ada Lovelace, Grace Hopper, Katherine Jones and others are known far beyond computer science circles for what they've made possible. By the 21st century, women were leaders in many tech companies, such as Marissa Mayer, the first Google female engineer, vice president of Google Search Products and User Experience, and former president and CEO of Yahoo!.

Many of the women who have contributed fundamentally to the data science field have been women of color. Katherine Johnson and Mary Jackson made pivotal contributions to scientific instruments and offered their engineering skills to NASA, while Gladys West was responsible for the mathematics that brought about the invention of the Global Positioning System. The inclusion and celebration of diverse minds and voices in data science provides a richness of perspectives that is essential to the innovation, growth, transdisciplinary nature, and very future of the field.

Photo of Fran Allen


Fran Allen is an American computer scientist and a pioneer in the field of optimizing compilers. Among her lifetime accomplishments, Allen was the first woman to be awarded the Turing Award (2006). Her contributions to computer science include seminal work in program optimization, compilers and parallelization. She was the first female IBM Fellow, and in her honor, the IBM-sponsored Allen Medal was created in 2020 that recognizes innovative work in computing that has led to a lasting impact on the field of engineering, technology or science.

Born in 1815 in England, Ada Lovelace recognized the potential of mathematical machines to make more than pure calculations, and she published the first algorithm to be carried out by one, making her the first computer programmer. She is mainly known for her work on the Analytical Engine, which is known as the first computer but was never built because of a lack of funding. More
