Olli Erkki Lehto (born May 30, 1925 in Helsinki ) is a Finnish mathematician who deals with function theory.
Lehto received his doctorate in 1949 from the University of Helsinki under Rolf Nevanlinna ( application of orthogonal systems to certain function-theoretical extremal and mapping problems ). From 1961 to 1988 he was professor at the University of Helsinki, from 1978 as dean of the mathematics faculty, from 1983 as rector of the university, from 1988 to 1993 as chancellor.
