Description: (Mathematician, Philosopher, University teacher, Computer scientist)
Alonzo Church was a prominent American mathematician, computer scientist, logician, and philosopher who made significant contributions to mathematical logic and theoretical computer science. His research on the lambda calculus, the Church–Turing thesis, the unsolvability of the Entscheidungsproblem, the Frege–Church ontology, and the Church–Rosser theorem has had a lasting influence on the field. Church, along with his doctoral student Alan Turing, is acknowledged as a key figure in the development of computer science, playing a vital role in shaping its foundational principles.
