I’ve read a bit about Caroline Herschel, often in the context of “here are women who did important things in science who don’t get enough recognition.” She was one of those women who helped a man get lots of science done – in her case, her brother William: she was his assistant for much of his observing life, writing down his observations and helping with his frankly unwieldy telescopes, as well as keeping house for him for many years until he married – and then his wife had money so they had more servants. All of those things are immensely important and often get overlooked; no one is able to do science on the scale of William Herschel, or Robert Boyle, or Charles Darwin, without an immense amount of assistance: usually either female, lower class, or both. Hence why that assistance is often overlooked, because the European narrative in particular is much happier with the ‘great man’ theory.

To leave Caroline’s story at that, though, is to do her an immense disservice. She was an astronomer in her own right, discovering eight comets (two of which she wasn’t the official discoverer, because someone else got there first, but she didn’t know about that when she found them). She also contributed observations to William’s immense catalogue of the ‘nebulous’ stars. In the late 1700s, most people assumed that that ‘cloudy’ or nebulous patches in the sky were simply stars that contemporary telescopes couldn’t resolve. William used the largest telescopes of the time to realise that actually, some of those areas actually couldn’t be resolved – they really did look cloudy – and suggested that maybe some of those areas were where stars were born. (He also discovered Uranus – the first planet to have been discovered by a human, rather than seen naked-eye, which is what shot him to fame.) Caroline personally observed and described some of the Herschel catalogue.

And then there’s the other scientific tasks she undertook, which might be easy to skim over because they don’t seem that sexy. She worked for years on a massive index and catalogue of stars, using the main one available in English: double checking for errors, making it systematic, and so on. Not glamorous, requiring hours of probably boring labour, required a great deal of knowledge – what an amazing contribution to astronomy.

Anyway, the biography: is not entirely what I was expecting! It focuses largely on a decade in the middle of Caroline’s life, her most scientifically productive – and a decade for which she destroyed her dairy entires and never discussed in either of the two memoirs she produced later in life. There’s a lot of speculation for why this might be; most people conclude that it’s because she wrote some bitchy stuff about her new sister-in-law and that this didn’t fit her self-image as meek, self-effacing, and doing everything for family. It’s a fascinating question and one that will almost certainly never be resolved. So Winterburn has used letters, information from journals, and references in other places to reconstruct those lost years, and in doing so to highlight just how phenomenal Caroline was as a scientist. While she wasn’t the first women to be paid to do science – lots of other women were doing ‘science’, it just wasn’t usually called that – she was the first English woman to have a royal pension for doing science, and that’s very damn impressive.

There are oddly repetitive bits throughout the book, where Winterburn repeats ideas or phrases that have just been laid out a paragraph or two earlier; and the book can’t solely concentrate on the one decade, because the reader needs greater context for Caroline’s life – so it’s not without flaws. There’s also a frankly odd emphasis on the events of the French Revolution; while it certainly had a huge impact on some of the people Caroline and her brother corresponded with, it didn’t actually seem to have a direct impact of Caroline, living in England – she wasn’t obviously a supporter of either Burke or Paine (anti or pro the revolution), so I was confused by how many ink was spent discussing those foreign events. Nevertheless, overall I really enjoyed this, and am immensely pleased to know more about Caroline. To the point where I’m considering the so-called Herschel 400 as an observing list.
