Alexandre Preissmann was born in Neuchâtel, Switzerland and studied for a degree in mathematics at ETH, Zurich, graduating in 1938. In 1942 he obtained his PhD for a study of the mathematics of Riemann spaces. From 1946-1958 he worked at the ETH Versuchsanstalt für Wasserbau directed by Eugen Meyer-Peter (1883-1969).
