Adele Goldstine - pioneering programmer

I've been doing some reading lately about the women who programmed the ENIAC computer, and was thrilled to learn that these six amazing women were trained by another amazing woman: Adele Goldstine!

Working on the team developing the ENIAC computer, Adele Goldstine trained several of the original six women programmers, and then wrote the ENIAC Operators Manual based on what they discovered as they taught themselves how to program it.
Adele Goldstine (December 21, 1920 – November, 1964) earned her masters in mathematics from the University of Michigan, and then went to teach at the Moore School of Electrical Engineering, at the University of Pennsylvania. That's important, because that's where the US Army set up their Ballistics Research Laboratory. Adele worked as a mathematics instructor for the women computers tasked with doing the calculations by hand.

That's also where they built the ENIAC computer, the very first programmable, electronic, digital computer, designed to solve large-scale problems -- like ballistic trajectories. Adele trained several of the original six women programmers, who were set loose on the machine to figure out how to program it. Being the first of its kind, no one really knew what it was capable of or how to go about programming it. So these women just figured it out.

Adele wrote the ENIAC Operators Manual (Bookshop/Amazon) based on what they discovered as they taught themselves, enabling more programmers to use the machine throughout the war. At first, each time the ENIAC was used, it had to be programmed from scratch, but eventually Adele figured out how to get it to "save" several key functions, saving the time of having to set it up again fresh.

You can learn more about her life and work in this excellent piece by the Society of Women Engineers.

This amazing woman was a trail-blazer, and nearly 25 years after her death, Rear Admiral Grace Hopper is still a role model whose life and achievements continue to serve as a positive influence for pretty much everyone. Her wisdom can help us find strength when we need it most, and encouragement to keep working even when it is difficult.
Margaret Hamilton - pioneering software engineer
Computer science pioneer Margaret Hamilton built the field of computer software engineering as she went along. The brilliance of her work wasn't so much that she build a system to help the astronauts reach the moon, but that she built it to basically save them from their own mistakes.
Uncovering Stories: Raye Montague - Navy Engineer
She was promoted into a civilian position with the equivalent rank as a captain, working as the Program Manager of Ships, in charge of the entire process of building a ship -- a dream job that combined her engineering talents with her business degree. She was the first woman to earn that position and she took it very seriously.
