George Grätzer

George A. Grätzer (Hungarian: Grätzer György; born 2 August 1936, in Budapest) is a Hungarian-Canadian mathematician, specializing in lattice theory and universal algebra. He is known for his books on LaTeX[1] and his proof with E. Tamás Schmidt of the Grätzer–Schmidt theorem.[2][3]

Biography

His father József Grätzer was famous in Hungary as the "Puzzle King" ("rejtvénykirály"). George Grätzer received his PhD from Eötvös Loránd University in 1960 under the supervision of László Fuchs.[4] In 1963 Grätzer and Schmidt published their theorem on the characterization of congruence lattices of algebras.[5] In 1963 Grätzer left Hungary and became a professor at Pennsylvania State University. In 1966 he became a professor at the University of Manitoba and later a Canadian citizen. In 1970 Grätzer became the founder and editor-in-chief of the journal Algebra Universalis. His mathematical articles—over 260, all listed on Research Gate—are widely cited, and he has written several influential books.

Grätzer has received several awards and honours. He is married and has two children (Tom Gratzer and David Gratzer) and five grandchildren.
