ENIAC: Betty Jean Jennings Bartik

The ENIAC's main control panel with Bartnik on the left.

Bartik was one of the leading developers of the ENIAC trajectory computer, and she was quite proud of its first public presentation in 1946:

“The day ENIAC was introduced to the world was one of the most exciting days of my life. The demonstration was fabulous. ENIAC calculated the trajectory faster than it took the bullet to travel. We handed out copies of the calculations as they were run. ENIAC was 1,000 times faster than any machine that existed prior to that time. With its flashing lights, it also was an impressive machine illustrating graphically how fast it was actually computing.”
