back to article Mary Coombs, first woman commercial programmer, dies at 93

British programmer Mary Coombs, the first woman to program a computer designed for commercial applications, passed away on February 28 at the age of 93. Coombs (née Blood), was born in northwest London on February 4, 1929 to William Blood and Ruth Blood (née Petri). She graduated from Queen Mary University London with a BA …

    I read 'A Computer Called Leo' with a dropped jaw - to realise that an old valve machine was used far more intensely than most Windows machines, and many modern ERP systems was mindblowing. Condolences to her family.

      "According to the UK's Science Museum, this was the first routine, real-time office application."

      I like to think of it as an operational research/industrial one. Payroll came later as the article mentions.

      Read the linked PDF. Fascinating. And, as the article says, things don't change. They were working with the French firm Bull and she was doing some technical translating of manuals in her own time. When she suggested they pay her for that they outsourced ot to a firm of translators instead.

      I also have a copy and knew one of the people who worked on EDSAC, which the LEO was based on. Unfortunately, at the time (1968/69) I'd never heard of EDSAC.

      If you're interested in computing history then, alongside "A computer called LEO", your library needs a copy of "A Brief History of the Future" by John Naughton, which described the history of the Internet. Again, I've met one of the people involved, this time Roger Scantlebury, in 1984 at Logica.

        For those who are interested in history, I have an original copy of the GB Government's 1953 report into computing. It includes such insights as "... a machine has been developed that has run for an entire weekend without servicing." That machine was LEO. :-)

        They also concluded that only about 5 computers would ever be required ... I assume the producers of this report were related to the beancounters who produced of the subsequent Government report concluding that "there is no economic future for satellite technology" at the height of the British space launch programme? :-(

        Interesting that many of the first computer programmers/operators were women and this continued into the 60s mainframes.

        Assuming that this was because it was considered closer to telephone switchboard operator, in the early days, and then just 'typing' once consoles appeared. While the soldering wires was obviously 'proper' electrical engineering and therefore man's work.

            That was because women were not encouraged to study sciences! Indeed a friend of mine at the local Girls Grammar School nearly started WW3 before she was allowed to study A'Level sciences at the school. This would be 1974! When went to Uni 3 years later there were only 3 women on my Electrical And Electronic Eng course out of over 60 and they did not receive a warm welcome from a large part of the intake. It must have been hell for them as their is nothing worse than obsessive sexist autistic engineering students on their case, something I only found out after graduation as I tended to skip most classes.

              There are exceptions to the rule. My wife is the eldest of a family of three girls who all graduated in Physics in the early to mid 70s from British universities. They went on to get postgraduate degrees in the subject. Their parents were normal, not heavy duty scientists, feminists or whatever, so I'd guess their subject choice was a combination of inherent aptitude and their parents forgetting to drum into them stuff like "Girls Don't Do Math". (Which is a lie, anyway.)

              They're now retired and the missus can can pass muster as a generic older lady. Incidentally, she hates computers with a passion despite being around them for 40-50 years.

          This happened at NASA because "computers" were human beings for the first half of the 20th century and the electronic variety was about to put many of them out of work.

          The skullduggery, assumptions, biases and sneakery of management was more than matched by a bunch of highly intelligent and undervalued women determined not to become unemployed

          It turned out they were able to solve problems with the newly installed systems (out of hours, without authorisation and without knowledge of the management) that even IBM's installation techs couldn't figure out (a good chunk of which was down to miswiring)

            The movie "Hidden Figures" shows a fair (not perfect of course, it's still a Hollywood product) account of the role of the 'calculators', and how they managed to adjust to the introduction of computers.

            John Glenn requested that one of them, Katherine Johnson, go over the calculations for his flight before he was confident enough to plonk his butt on top of some 100 tons of kerosene and LOX and have it fling him into earth orbit with sufficient chance to get back down. In one piece.

          Even in the early 80s: I was supposed to be going to work for ICL (they cancelled all recruitment before I got there...) but at the time they boasted of their (relatively) progressive attitude to maternity leave and allowed women to work from home (albeit doing the tedious stuff like finding and fixing bugs). My gut feeling is that there were proportionately more women working in IT in those days and in more senior positions.

          And, actually, a lot of electrical assembly was done by women. Core memory arrays were frequently made by women owing to the dexterity and patience (perceived to be) required to thread the fine wires. And, of course, they got paid less.

          It seems that gender roles get further reinforced when industries go "mainstream".

          This isn't intended to denigrate Margaret Hamilton in any way, shape or form - but one of the reasons you know about her and not many of the other brilliant female engineers/programmers at NASA - such as Katherine Johnson, Dorothy Vaughan or Mary Jackson (all crucial programmers in various arenas) is because she's white

          NASA's facilities - Johnson in particular - were in the heart of segregationist country in the 60s and it showed. Several NASA administrators fought tooth and nail to keep women out and even harder to keep black women out

          This atittude was stll showing at the end of the 1960s despite presidential equality orders and the appointment of James Webb with a mandate to desegregate the agency (This is WHY the telescope is named after him) - the work and effort of black employees was played down or flat out "disappeared" right into the 1970s

            But it is denigration, and you know it. She got the positions she got in the late '50s and early '60s DESPITE being female in a world of men. Which means that she worked her ass off. Bringing race into the issue makes it sound like she merely lucked into the jobs simply because she was white, which is total and complete bullshit, and indeed a form of racism in and of itself.

            Before you poo-poo this, THINK about it ... The only reason for your derogatory comment is because of her skin colo(u)r. Isn't that the very definition of racism?

            I don't remember MLK saying "I have a dream that my four little children will one day live in a nation where they will judge white people by the color of their skin, instead of the content of their character." ... do you?

      I heard of her. My A Level Computer Studies teacher, back in 1978/79 was a woman, a Systems Analyst on secondment, She had some great stories, including about women in computing, so it never feels odd to me to meet women in tech fields as it does for some others of my generation. I guess what you learn and the examples you see in your formative years really does have an effect on your outlook throughout your life.

        Re: First time I heard of her -- thanks!

        We also had a teacher in '78-'79 who had a degree in computing. She taught maths because in state schools in the East Midlands there was no such thing as computer studies. She was willing to teach us about computing after school but the headmaster believed that "Computers are just a fad, nothing will come of them.", so he wouldn't let us use a classroom after hours. He was such a unremarkable bureaucrat that I can't even remember his name. The school was Wulfric Comprehensive in Burton upon Trent.

          TBH a "degree in computing" at that time was a rarity - most were maths or electrical engineering based with computing as part of the degree. Even in the 80's I was the only employee in the FE college IT teching department with a qualification in computer science, nearly all the specialist lecturers were maths or electronics trained and most were time-served in computing environments.

          Re: Paper tape at first.

          I know about Jacquard looms; I grew up in a textile area and my holiday jobs were when I was young were in milla.

          Jacquards are more limited in function than you may think. None that I saw in the mills 60 years or so ago could do no more than control healds so although they were capable of making complex patterns in the warp they were no use if there was more than one weft. In the woollen mills of the West Riding Jacquard mechanisms were limited to what were termed "Woven lists", lettering woven into the edges of the cloth saying things such as "SUPERFINE WORSTED". The main control mechanism on looms such as the Dobcross used a chain rather like a very heavy bicycle chain with disks on the cross-pieces of the links. The disks acted as cams and although they could only control a limited number of sets of healds - AFAICR the biggest gears we had used about 12, they could control the selection of the shuttle boxes, i.e. the weft.

          None of this is relevant to Mary Coombs's story. If you read the PDF linked in the article you'll find that although punched cards were used for storing data - Lyons already used them already with tabulators - the programs were entered on paper tape.

            Re: Paper tape at first.

            I learned card weaving (kind of a cross between simple backstrap weaving and Jacquard ... look it up) back in the 1960s in Palo Alto. It was a bit of a fad at the time, you can see hippys wearing belts and headbands made this way in photos of the era. I made the guitar strap that I still use today in roughly 1970.

            Creating new patterns (including lettering in a variety of fonts) is without a doubt simple programming ... Did it help shape my mind for the computer revolution that was to come? Probably. Hard to say for sure ... but I made sure to teach my daughter this deceptively simple technique.

            Give it a whirl. It's cheap (you can make all the hardware at home, even if you're not particularly handy), relaxing and a useful skill in that you can make custom flat webbing for almost any need.

              I remember having a toy loom in the mid '70s as a kid. It had a frame with a lot of wool threads, and another swinging frame with a lot of wool threads you pushed back and forth as you passed a shuttle with some more wool left and right.

              As you can see, I got the terminology down pat. Seriously though, it was a lot of fun, even though you didn't end up with anything useful at the end.

              I don't remember much about it, but I Googled "toy loom" and what I had was far more complex and made of lots of heavy plastic.

    Interference.

    My guess would be vibrations from the lift passing playing merry hell with the pulses in the delay line memory?

    Anyone?

    1. NorthIowan

      Re: Interference.

      Most likely.

      But valves can be sensitive to vibrations to. It would depend on how they were biased. If the logic was running in a too linear of a region they might perturbed by vibrations. And the drivers and receivers for the delay lines might well have had some linear amps.

      Re: Interference.

      Starting and stopping the lift played merry hell with harmonics in the mains.

      Picture a data center in the basement of a tall building in San Francisco's financial district. Card punch up against a wall, near the ancient Otis heavy goods lift. Every now and again, at seemingly random times, the punch generated errors for a couple characters. Nobody could figure out why, not even IBM's field circus dudes.

      Until IBM was traipsing in and out one fine weekend, upgrading who knows what hardware, as only IBM could. Someone (ahem) noticed that the gibberish was being generated about ten seconds before the elevator doors opened.

      Turned out that the motor for the lift was drawing so much current when it first started that it was inducing errors in the punch on the other side of the wall. Nobody put two and two together prior to this because the lift rarely went into the basement (that level was key-protected) ... until IBM was in and out that morning.

    In the greater world

    Outside of England I would mention Konrad Zuse.

    "Konrad Ernst Otto Zuse ( 22 June 1910 – 18 December 1995) was a German civil engineer, pioneering computer scientist, inventor and businessman. His greatest achievement was the world's first programmable computer; the functional program-controlled Turing-complete Z3 became operational in May 1941. Thanks to this machine and its predecessors, Zuse has often been regarded as the inventor of the modern computer.

    Zuse was noted for the S2 computing machine, considered the first process control computer. In 1941, he founded one of the earliest computer businesses, producing the Z4, which became the world's first commercial computer. From 1943[8] to 1945[9] he designed Plankalkül, the first high-level programming language.[10] In 1969, Zuse suggested the concept of a computation-based universe in his book Rechnender Raum (Calculating Space).

    In 1950/1951, the Z4 was the only working digital computer in Germany, and the second digital computer in the world to be sold, beating the Ferranti Mark 1 by five months and the UNIVAC I by ten months, but in turn being beaten by the BINAC (although that never worked at the customer's site[21]).

        Re: Ice cream full of air was a stroke of genius

        Without air, you don't have ice-cream, you have a solid block of blech.

        Ice-cream is a freeze-stabilized foam ... The milk/cream/sugar/flavo(u)r mixture is foamed with air while being frozen. Without the foaming process, the individual ingredients will separate out during the freezing process (fractional distillation by crystallization), leaving a mess. You can demonstrate this for yourself by mixing up any recipe for ice-cream and popping it into a freezer without using an ice-cream maker. Then thaw it out and make it it properly, waste not want not.

        Think you don't have an ice-cream maker? Think again ... use your favorite webby-pointy-clicky-searchy-thingie to look up "Tin Can Ice-cream".
