The ENIAC was the first programmable, electronic, general-purpose digital computer, completed in 1945.

The ENIAC six:

Kay McNulty, Betty Jennings, Betty Snyder, Marlyn Wescoff, Fran Bilas and Ruth Lichterman

Not only did the women have to translate their calculations into steps that the ENIAC could handle, but they also had to literally wire the machine, said Kathy Kleiman, historian, author, and founder of the ENIAC Programmers Project, in a 2018 TEDx Talk. “They had to track each piece of data, wire it into a panel, such as a multiplier or a ‘square rooter,’ and then move the result — physically by wire — to another panel for storage,” she said.

It's why one of my favorite quotes is, "We stand in the shoulders of giants." Those 6 women are some of many giants for which humanity today owes its progress to. Its moments like this video I'm reminded what it took so that I can casually use a device with ease.

Not to shit on what this post is saying, but ENAC was not the first programmable computer, that was the Colossus developed by the British, while not programmable with digital code, it was programmed by changing the switches physically. However that was the first digital computer.

Good she delivers how they got recognized. Those stories sometimes as equally unbelievable as the original stories. Wait till you hear about the woman discovering Olympe de Gouges. (It's late, Im tired, I don't remember the name and its difficult to Google but its worth the research)

I was curious if they helped Alan Turing. It would be interesting to find out how they collaborated. Well, if sexism didn't probably keep them apart. All I found is this

This is incorrect. Although possibly excusable. The first digital computer was invented by John Vincent Atanasoff and Clifford Berry at Iowa State University. https://en.m.wikipedia.org/wiki/Atanasoff%E2%80%93Berry_computer

Funny how in times of war all societal standards and norms go out the window. Same thing happened during the space race with the women who programmed the first NASA computer. War can drive very progressive thinking, because winning is all that matters.

Don't know why this isn't upvoted more. I'm a female senior software engineer. My work is constantly questioned, and my male colleagues often take the credit. Times havent changed much, unfortunately.

Yeah, I remember ENIAC. I had to pilot a giant robot, fight countless enemies, and go back in time to swap out a vacuum tube on it. This was all to prevent a super-intelligent AI from destroying humanity.

The first description of Eniac is wrong - it wasn't the first electronic digital computer - that was Colossus. But the longer description is right.

Hate to break it to you, but ENIAC was the first _American_ programmable electronic computer. The Brits beat you by a couple of years with Colossus.

I remember in college reading an old old paper where it started it with lamenting how the paper was late to the previous conference because his calculator died. It took me several paragraphs before I realized he meant a Calculator. As in a person with a title.

The first programmable, electronic, general-purpose digital computer was the Colossus, built by Tommy Flowers at Bletchley Park in 1943 (Mk I) and 1944 (Mk II). A total of twelve units of the latter model were made. However, their existence was kept secret until the 1970s, while the ENIAC was made public in 1946.

Yes, but this is about the women who have been stripped of their achievements in history of science.

was casting around to confirm someone had already mentioned this ... not to take away from anyone involved in ENIAC ... saw the reconstructed one in place at Bletchley Park in 2007 which was a thrill ...

Also, the worlds first computer to be owned by a business, and the first to be used to run a business (stock control, accounting, production planning etc) was LEO, built by Lyons, a British bakery/cafe chain. https://en.wikipedia.org/wiki/LEO_(computer) Lyons actually designed and built it themselves, and then started making them for other companies. That operation ended up as ICL and is now owned by Fujitsu.

It's mad that women essentially drove modern computing in to existence independently in various countries but were all swept under the carpet by their respective nations. We owe them a lot.

This is true of so many people who had some undesirable traits at their time, like being a woman back then, gay, black and so on; all robbed of the credit for their often history-defining contributions.

Some in the last 40 years have finally been getting the credit due, but almost a century late when they often arent here to see it.

And yet people question why we have women’s history month or black history month.

Well that's just because men are clearly better... Hence why we need to hide the fact that half of or more great inventors, thinkers, and philosophers are women! Because if we didn't...uh.... Women wouldn't know...erm... That they're the inferior ones.... And men might feel threatened, no no no, not threatened, uhhh... Insulted! By the smarter, no, inferior and uppity women! Yes, that. Ok now, off to steal some ideas from some women and convince myself it was my idea all along! Busy busy!

It's even more bleak when you look at demographics in computing, data processing, and computer science up through the 70s. The fields were full of women... and then the home computing revolution made it viewed as a lucrative & prestigious field, and almost overnight the demographics shifted and women were pushed out.

Unlikely that will be permanent. Not only are the archives not built that way, they have storage for all of that and more. Librarians are not exactly kindly about being asked to remove volumes from their collection without good reason. Not only that, but previous admins have profiled and suppressed diverse history with little future effect. History's caretakers tend to save and reintroduce purged information after the orders are done with. NASA is a past modern example.

So you possibly now know that Eniac was not the first programmable computer.

The first, by a long shot, was the Babbage Analytical Engine.

Then you have the Zuse Z1, Zuse Z2, Zuse Z3, the Atanasoff–Berry computer, and of course the Colossus, a computer designed by a team led by Tommy Flowers (of the British General Post Office) at Bletchley Park, the UK's codebreaking center.

Women of color also angered doctors at the end of slavery. This topic has always interested me. Their success rates were higher, and therefore they were made spectacles of in awful fashion, including an incompetent character in a Charles Dixons novel. Some were made to go to classes with doctors who would tell them their methods were wrong. Many doctors invented their own devices with no oversight, and some tools were often deadly. Their impact has stood the test of time and I'm glad for that.

I'm a man but think women have so much larger part in programming than given credit for. Grace Hopper pretty much invented the compiler and was way too modest about it. And Heddy Lamar, yes the fucking actress, invented frequency switching with another person in her spare time that made later inventions like Bluetooth possible.

She (Heddy) even applied for a patent (though i think it got rejected). She came up with the idea of frequency hopping while watching a piano getting tuned

I don't know how it was possible before, but now you have to make the post private, then add new stuff, then make it public again. I did this once and all comments are gone + the point count is reset, so it's basically like a new post. I didn't check though if the same URL applies. Also I saw IIRC the upvote downvote got confused by this and still added the old number up, but the resulting count was nulled.

Just had a look and in the new app you have to make it hidden, add pictures, save, make public again. It recreates a new url then. Boooo! I stand corrected. You can’t add them to an existing post AND kept the same url. 🤬
