John Riordan
From Wikipedia, the free encyclopedia
John Riordan was an American mathematician and author of major early works in combinatorics, particularly Introduction to Combinatorial Analysis and Combinatorial Identities. He worked most of his life at Bell Labs.
From an interview with Neil Sloane published by Bell Labs:
- Even at the end of my first year as a graduate student at Cornell, in 1962, I managed to arrange a summer job at Bell Labs in Holmdel. This was still on minimal cost networks. During that summer I met another of my heroes, John Riordan, one of the great early workers in combinatorics. His book An Introduction to Combinatorial Analysis is a classic. He was working at Bell Labs in West Street in Manhattan at that time. One of my earliest papers, on a problem that came up in my thesis work, was a joint paper with him.
