In 1946 six brilliant young women programmed the first all-electronic, programmable computer, the ENIAC, a project run by the U.S. Army in Philadelphia as part of a secret World War II project. They learned to program without programming languages or tools (for none existed)—only logical diagrams. By the time they were finished, ENIAC ran a ballistics trajectory—a differential calculus equation—in seconds! Yet when the ENIAC was unveiled to the press and the public in 1946, the women were never introduced; they remained invisible.

The ENIAC Programmers Project has been devoted for nearly two decades to researching their work, recording their stories, and seeking honors for the ENIAC Six—the great women of ENIAC.
