I didn't know about her; the Wikipedia entry is at:

In another page she talks at length about her life:

The rest of the comment is quotes from that page because it's quite long but I found it very interesting:

The Differential Analyzer room was marked as a “Restricted” area and the door to it was kept locked. It was also the only air-conditioned room in the Moore School. It was air conditioned to maintain a constant temperature so the Analyzer hardware would not be affected by temperature changes because metal expands and contracts as the temperature goes up and down.

I’m not sure how restricted the analyzer room was the first summer I was there, the summer of 1942, because it was ungodly hot that summer and the professors would come down and use the room for meetings. Pres Eckert and a group of engineers were working on the roof of the Moore School under a contract with MIT. It was for radar studies. It was hot, they were all in shorts except Pres, and they would come in the Analyzer room to cool off.

The ENIAC had a feature that helped test a program as well as the hardware. It could be set to run at full speed, 100,000 cycles/pulses per second. Or it could be set to run one-add time at a time. There were 20 pulses in an add-time so it stopped at every 20 pulses. Or it could be set to run one pulse at a time. This gave the operator the chance to look at the state of the machine at these various intervals to determine just when an error had occurred. These controls were mounted on a small unit that could be held in the hand. It was attached to a flexible cable so it was a remote control. As operators, our job was to track down where an error had occurred. Once we found out which tube was malfunctioning it was up to the maintenance man, either Homer Spence or Goldstein, an army corporal, to replace the failing unit.

The worst thing that happened to John was the security clearance problem. It started in 1949. That was when they were building the Binac. When the notice of his denial of clearance came in, Mr. Straus was still alive. He said that he knew Hoover personally and he would get it cleared up. The company was not doing any work that involved security devices, they were just building computers. Straus did get it cleared up.

It was strange that each time his security was questioned, it came from the Philadelphia Ordnance Department. When I got John’s FBI file, it didn’t tell me where the information came from. But, it always came from Philadelphia. It was so persistent..

This file shows that John was a subscriber to Consumer Reports which was declared communist oriented. Also, it shows him as a member of the Association of Philadelphia Scientists. John declared that he never joined such an organization The only thing he could figure out was that he may have put his name on a list for literature at some time and they took that as joining. He was also accused of hiring security risks, such as Bob Shaw.

Bob was a brilliant engineer and an albino with very limited eyesight. Bob owned a car. He could not see well enough to drive so he had various friends chauffeur him around. One time, one of his friends asked to borrow the car to drive to Washington, D. C. The friend drove it to Washington on a weekend when there was a parade that was considered pinko-oriented. Bob’s car was parked on the street while the chauffeur visited a friend. The police went along the street writing down license plate numbers. They traced the car to Bob. Bob wasn’t even there. Bob was also cited as getting various organization newsletters.

All the years I gave talks about the ENIAC, I always talked about it as John’s story, not my story. Although I mentioned that I had been an ENIAC Programmer, it was just in passing.

The only thing that I really regret is that Pres and I did not write our book about the ENIAC, EDVAC and Univac. Pres was always very angry about the lies that were told and copied from one book to the next, He said that they could go ahead and write their books, but he and I would write one telling the real story. [...] Somehow, we were wrapped up in our lives and never got around to writing the book.

If I am remembered at all, I would like to be remembered as my family storyteller. It has been a great life.
