After studying mathematics at the University of Vienna he received his doctorate in 1968 under Edmund Hlawka.^[1] He held visiting professorships in Technical University of Vienna, University of Manchester in 1969, Bedford College (1969–1974) and the University of Warwick from 1974 to 1994 after which he came back to the University of Vienna. He retired in 2009. In 1975/76 K. R. Parthasarathy invited Klaus Schmidt to spend 7 months at the new Delhi Centre of Indian Statistical Institute (Parthasarathy was then working at the Indian Institute of Technology, Delhi).

In 1994 he was awarded the Ferran Sunyer i Balaguer Prize for the monograph Dynamical systems of algebraic origin. He is member of the Austrian Academy of Sciences.

He has researched among other things, ergodic theory and its connections with arithmetic, commutative algebra, harmonic analysis, operator algebras and probability theory.
