Women have been fundamental to the growth of data science and programming for many years. Throughout the 19th and early 20th century, and 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. Names like Ada Lovelace, Grace Hopper, and Jean Sammet have since circulated the big data landscape for their substantial contributions to the industry. By the 21st century, women began to take on leading roles in many tech companies, such as Marissa Mayer, former president and CEO of Yahoo! and key spokesperson at Google.

Many women of color have been acknowledged for their contributions to the data science field as well. 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 (GPS). Diversity in the field of data science provides a variety of perspectives that are essential to the innovation, growth, and trans-disciplinary nature of the industry as a whole.

Women around the world are blazing a trail in the world of big data, and as years progress, the opportunities seem endless for what they can achieve.
