Jean Jennings Bartik, the last of six women programmers who debugged and operated the earliest general-purpose computer, has died.
Bartik graduated from Northwest Missouri State Teachers College in 1945 as the school's one math major.
She took a train to Philadelphia to work for the military.
There, she learned ballistics calculations and was quickly hired to work on the ENIAC, created during the war by University of Pennsylvania scientists John Mauchly and J. Presper Eckert Jr.
Bartik and her colleagues debugged the computer, which weighed 30 tons, contained about 18,000 vacuum tubes and completed the same work the women "computers" did but in a fraction of the time.
Bartik went on to work on the BINAC and UNIVAC computers and to work in the fledging high-tech publishing field. Her children and grandchildren all grew up to be good with numbers, she said in February.
Bartik and the other ENIAC programmers didn't receive much attention for their work after WWII, but their story was recently featured in the documentary "Top Secret Rosies: The Female Computers of World War II." Bartik wrote an autobiography that is being edited; Rickman said he hopes it will be published this year.
