He is perhaps best known for his nonsense poetry - including The Owl and the Pussycat - but Edward Lear's career began as a scientific artist. From owls and turtles, to lemurs and giant squirrels - he created colourful illustrations to help scientists with their research.
Some of his artwork is now on display at the Royal Society in London. Take a look with Jonathan Ashmore - the chair of the Royal Society library committee and lifelong Lear fan.
