CHICAGO (CBS) — On Veterans Day, we honor and remember the brave women and men who fought for and served our country. But for those in tech, today is an especially good day to thank the military servicemen and women who during WWII developed much of our beloved computer technology and used it to bring the war to a swift and final end.

Computers, as we know them, were created in the late 1930s/early 1940s to do complicated mathematical equations faster. During the war years, the military built and used these computers to test and calculate the trajectory of newly developed rocket propelled weapons as well as decode enemy secret messages.

After the bombing of Pearl Harbor, when the US officially entered into WWII, many American men enlisted to fight for their country. But so did American women. And while women weren’t officially allowed to hold combat roles in the US Military until 2013, women became pilots, radio operators, engineers, mechanics, nurses and, though the term wouldn’t be coined until nearly two decades later, computer programmers.

Many female mathematicians like U.S. Navy Lieutenant Grace Hopper, U.S. Navy Ensign Ruth A. Brendel (Mark I) and the British women who worked at Bletchley Park (the Colossus) were the very first people to use these top secret experimental computing machines to determine ballistics calculations, crack encrypted messages, and run the complicated mathematical programs that would eventually enable the US to develop the nuclear bomb.

Because it had never been done before they, along with their fellow female civil servants who worked with the U.S. Army (ENIAC 6), had to design, improvise, and debug the world’s first computer programs.

Until recent activities to bring their efforts to light through documentary projects like the Grace Hopper Movie and The Computers, military women’s stories have been lost not only to the public at large, but to the tech industry itself. Many a young brogrammer is shocked to discover his ilk didn’t invent the 24-hour coding marathon.

The military women of computer programming slept in shifts, keeping their top secret computing machines running around the clock in an effort to out-calculate their WWII enemy.

So next time you power on your laptop, tablet, or smart phone, remember the dedicated military women of WWII. Not only did they aid in bringing an end to a great and terrible war, they also birthed the computing industry as we know it.
