Busy couple of week meant I was a bit slow at finding a new candidate. But I've managed to dig up another one continuing the historical theme.
As for the previous edition, which was "off the hooke" it was none other than Robert Hooke, the scientist who coined the phrase "cell". He was one of those super scientists in that he wasn't content with describing and coining the word "cell" but also described a physical law too. He also wasn't that far off working out gravity and he made his own microscopes so he could draw small creatures. Basically if he was around today he'd put a dozen different types of postdocs out of work. I'm jealous as I'm more likely to break a law than have one named after me.
