1924: Mathematician and statistician John Nelder born. He will contribute to experimental design, analysis of variance, computational statistics, and statistical theory. He will also be responsible, with Max Nicholson and James Ferguson-Lees, for debunking the Hastings Rarities.
1942: Physicist, mathematician, and engineer Sergey Chaplygin dies. He is known for mathematical formulas such as Chaplygin's equation, and for a hypothetical substance in cosmology called Chaplygin gas, named after him.
1985: Mathematician, cryptographer, and author Gordon Welchman dies. During the Second World War, he developed traffic analysis techniques for breaking German codes.
