Michael Makkai

Michael Makkai (Hungarian: Makkai Mihály, 24 June 1939 in Budapest, Hungary) is Canadian mathematician of Hungarian origin, specializing in mathematical logic. He works in model theory, category theory, algebraic logic, and in the theory of topoi. He graduated from the Eötvös Loránd University, Budapest, then worked at the Mathematical Institute of the Hungarian Academy of Sciences. He learned logic from Rózsa Péter and Andrzej Mostowski, Between 1974 and 2010, he was professor of mathematics at the McGill University. He retired in 2010. He is an external member of the Hungarian Academy of Sciences (1995).
With Leo Harrington and Saharon Shelah he proved the Vaught conjecture for ω-stable theories.
