I noticed an obituary of John Maynard Smith in a recent issue of Trends in Ecology and Evolution. It ended with a nice anecdote I hadn't seen before.

In the early 1950s JMS was studying at University College London under J B S Haldane. One day Haldane brought a visitor into the lab and asked JMS to explain what he was working on. JMS, who was studying the aerodynamics of animal flight, began to explain his calculations on the blackboard, when the visitor suddenly grabbed the chalk and started amending the equations.

JMS: 'I'm sorry, I didn't quite catch your name...'

Visitor: 'Alan Turing.'
