10 Trailblazing Women in Tech History

March is Women’s History Month so we decided to look back at the contribution of 10 women to tech history.

We’re also sharing stories of women developers from the CodinGame platform directly on the CodinGame Blog. You can check them out here.

Ada Lovelace

Ada Lovelace, mathematician and writer, wrote what many consider as the first computer program in the late 19th century.

Grace Hopper

Grace Hopper devised the theory of machine-independent programming languages and invented one of the first linkers.

Sister Mary Kenneth Keller

Sister Mary Kenneth Keller was the first woman to receive a PhD in Computer Science.

Adele Goldberg

Adele Goldberg developed the programming language Smalltalk-80, which inspired the very first Apple computer.

Karen Sparck Jones

Karen Sparck Jones was a computer scientist developed the concept of inverse document frequency (IDF). This technology underlies most modern search engines.

Hedy Lamarr

Hedy Lamarr designed a system to defeat the threat of signal jamming during the war. The invention was later used in the development of Bluetooth, GPS and WiFi technology

Annie Easley

Annie Easley was a computer scientist, mathematician, and rocket science. She helped develop the Centaur rocket and was involved in the early development of the space shuttle program.

Elizabeth Feinler

Elizabeth Feinler worked at the Stanford Research Institute (SRI) as the manager of the ARPANET, the precursor to the modern internet. She oversaw the development of many key internet technologies and protocols.
