5 unusual facts about Alonzo Church


David Hilbert

At the University of Göttingen, Hilbert was surrounded by a social circle of some of the most important mathematicians of the 20th century, such as Emmy Noether and Alonzo Church.

Gary R. Mar

He was the last dissertation student of the 20th century logician Alonzo Church and currently teaches at Stony Brook University.

Logic programming

The use of mathematical logic to represent and execute computer programs is also a feature of the lambda calculus, developed by Alonzo Church in the 1930s.

Prototype Verification System

PVS is based on a kernel consisting of an extension of Church's theory of types with dependent types, and is fundamentally a classical typed higher-order logic.

Theoretical computer science

While formal algorithms have existed for millennia (Euclid's algorithm for determining the greatest common divisor of two numbers is still used in computation), it was not until 1936 that Alan Turing, Alonzo Church and Stephen Kleene formalized the definition of an algorithm in terms of computation.


Platonism

This modern Platonism (sometimes rendered "platonism," with a lower-case p, to distinguish it from the ancient schools) has been endorsed in one way or another at one time or another by numerous philosophers (most of whom taking a particular interest in the philosophy and foundations of logic and mathematics), including Bernard Bolzano, Gottlob Frege, Edmund Husserl, Bertrand Russell, Alonzo Church, Kurt Gödel, W.V. Quine, Hilary Putnam, George Bealer and Edward Zalta.
