The famous astronomer Herschel was responsible for a lot of accomplishments, including expanding and organizing the catalog of nebulae and star clusters, discovering eight comets, polishing and mounting mirrors and telescopes to optimize their light-gathering powers, and keeping meticulous notes on everything.
By being awarded a Gold Medal of the Royal Astronomical Society and being named an honorary member thereof, holding a government position and receiving a salary as a scientist, Herschel became the first woman to do so.
Caroline Lucretia Herschel, who was William’s younger sister by eleven years and was born on this day 270 years ago, did not have a penis, and so was ignored by history. Despite the honors she received, one of her great works, the aforementioned expansion of the New General Catalogue (NGC), was published with her brother’s name on it.
If you’re into astronomy at all, you know that the NGC is a big deal and has been constantly updated ever since.
While she lacked William’s junk, she shared his intellectual curiosity, especially when it came to space and studying the skies. It must have been genetic — William’s son John Herschel was also an astronomer of some repute — and it was his Aunt Caroline, not Dad, who gave him a huge boost.
She arranged all of the objects then in the NGC so they were grouped by similar polar coordinates — that is, at around the same number of degrees away from the celestial poles. This enabled him to systematically resurvey them, add more data about them, and discover new objects.
Caroline was not the first woman in science to be swept under history’s rug by the men. The neverending story of the erasure of women told in Hidden Figures was ancient by the time the movie came out, never mind the time that it actually happened. Caroline was in good company.
Maria Winckelmann Kirch, for example, was also an astronomer, born 80 years before Caroline and most likely the first woman to actually discover a comet. But of course history gave that honor to her husband, Gottfried Kirch, who was thirty years her senior. However, Herr Kirch himself confirms in his own notes that she was the one who found it:
“Early in the morning (about 2:00 AM) the sky was clear and starry. Some nights before, I had observed a variable star and my wife (as I slept) wanted to find and see it for herself. In so doing, she found a comet in the sky. At which time she woke me, and I found that it was indeed a comet… I was surprised that I had not seen it the night before”. [Source]
Maria’s interest and abilities in science came from a person we might think of as unlikely nowadays: a Lutheran minister, who happened to be her father. Why did he teach her? Because he believed that his daughter deserved the same education any boy at the time did, so he home-schooled her. This ended when Maria lost both of her parents when she was 13, but a neighbor and self-taught astronomer, Christoph Arnold, took her on as an apprentice and took her in as part of the family.
Getting back to Hidden Figures, though, one of the earliest “computers,” as these women of astronomy were known, was Henrietta Leavitt. Given what was considered the boring and onerous task of studying a class of stars known as Cepheid variables, she actually discovered something very important.
The length of time it takes a Cepheid to go through its brightest to darkest sequence is directly proportional to its luminosity. This means that if know the timing of that sequence, you know how bright the star is. Once you know that, you can look at how bright it appears to be from Earth and, ta-da! Using very basic laws of optics, you can then determine how far away the star is.
It’s for this reason that Cepheids are known as a “standard candle.” They are the yardsticks of the universe that allow us to measure the unmeasurable. And her boss at the time took all the credit, so I’m not even going to mention his name.
And this is why we have The Leavitt Constant and the Leavitt Telescope today.
No, just kidding. Her (male) boss, who shall still remain nameless here because, “Shame, shame,” took all of the credit for work he didn’t do, and then some dude named Edwin Hubble took that work and used to to figure out how far away various stars actually were, and so determined that the universe was A) oh so very big, and B) expanding. He got a constant and telescope named after him. Ms. Leavitt… not so much.
There are way too many examples of women as scientific discovers being erased, with the credit being given to men, and in every scientific field. You probably wouldn’t be on the internet reading this now if no one had ever come up with the founding concepts of computer programming, aka “how to teach machines to calculate stuff for us.”
For that, you’d have to look to a woman who was basically the daughter of the David Bowie of her era, although he wasn’t a very dutiful dad. He would be Lord Byron. She would be Ada Lovelace, who was pretty much the first coder ever — and this was back in the days when computers were strictly analog, in the form of Charles Babbage’s difference and analytical engines.
The former was pretty much just an adding machine, and literally one that could only do that. So, for example, if you gave it the problem “What is two times 27,” it would find the solution by just starting with two, and then adding two to it 26 times.
The latter analytical engine was much more like a computer, with complex programming. Based on the French Jacquard loom concept, which used punched cards to control weaving, it truly mimicked all of the common parts of a modern computer as well as programming logic.
Basically, a computer does what it does by working with data in various places. There’s the slot through which you enter the data; the spot that holds the working data; the one that will pull bits out of that info, do operations on it, and put it back in other slots with the working data; and the place where it winds up, which is the user-readable output.
The analytical engine could also do all four math operations: addition, subtraction, multiplication, and division.
An analog version of this would be a clerk in a hotel lobby with a bunch of pigeonhole mail boxes behind, some with mail, some not. Guests come to the desk and ask (input), “Any mail for me?” The clerk goes to the boxes, finds the right one based on input (guest room number, most likely), then looks at the box (quaintly called PEEK in programming terms).
If the box is empty (IF(MAIL)=FALSE), the Clerk returns the answer “No.” But if it’s not empty (IF(MAIL)=TRUE), the clerk retrieves that data and gives it to the guest. Of course, the guest is picky, so tells the Clerk, “No junk mail and no bills.”
So, before handing it over, the Clerk goes through every piece, rejecting that above (IF(OR(“Junk”,”Bill”),FALSE,TRUE), while everything else is kept by the same formula. The rejected data is tossed in the recycle bin, while the rest is given to the guest — output..
Repeat the process for every guest who comes to ask.
Now, Babbage was great at creating the hardware and figuring out all of that stuff. But when it came to the software, he couldn’t quite get it, and this is where Ada Lovelace came in. She created the algorithms that made the magic happen — and then was forgotten.
By the way, Bruce Sterling and William Gibson have a wonderfully steampunk alternate history novel that revolves around the idea that Babbage and Lovelace basically launched the home computer revolution a couple of centuries early, and with the British computer industry basically becoming the PC to France’s Mac. It’s worth a read.
Three final quick examples: Nettie Maria Stevens discovered the concept of biological sex being passed through chromosomes long before anyone else; it was Lise Meitner, not Otto Hahn, who discovered nuclear fission; and, in the ultimate erasure, it was Rosalind Franklin, and neither Watson nor Crick, who determined the double helix structure of DNA.
Finally, a note on the title of this piece. It comes from a 1982 comic strip called Frank and Ernest, and it pretty much sums up the plight of women trying to compete in any male-dominated field. They have to work harder at it and are constantly getting pushed away from advancement anyway.
So to all of the women in this article, and all women who are shattering glass ceilings, I salute you. I can’t help but think that the planet would be a better place with a matriarchy.
