This is one of several dozen books and periodicals from Alonzo Church's library that we were lucky enough to purchase at auction in New Jersey. Several of the books contain his signature, or a presentation inscription to him. Unfortunately, this copy does not have those signs of his ownership. [But please check our inventory for several others that do]. Alonzo Church (1903 - 1995) was professor of mathematics at Princeton University (1929-1967) and of mathematics and philosophy at UCLA (1967-1990). He was the founding editor of the JOURNAL OF SYMBOLIC LOGIC. Among his most influential contributions are Church's Theorem, Church's Thesis, the Church-Turing Thesis, and the Lambda Calculus. His work was of major importance in mathematical logic, recursion theory, theoretical computer science, and functional programming languages in general. Professor Church's creation of lambda calculus was the foundation for the LISP programming language and provided the semantic model for ALGOL. Church was first to demonstrate that David Hilbert's Entscheidungsproblem was unsolvable. It was Church who coined the phrase "Turing machine" for Alan Turing's hypothetical universal computing machine. He was elected to the National Academy of Sciences, British Academy, and the American Academy of Arts and Sciences. Church is regarded by many as the greatest American logician of the 20th century.
