Nikolai Luzin

Nikolai Nikolaevich Luzin (also spelled Lusin; Russian: Никола́й Никола́евич Лу́зин; 9 December 1883 – 28 February 1950) was a Soviet/Russian mathematician known for his work in descriptive set theory and aspects of mathematical analysis with strong connections to point-set topology. He was the eponym of Luzitania, a loose group of young Moscow mathematicians of the first half of the 1920s. They adopted his set-theoretic orientation, and went on to apply it in other areas of mathematics.
