- John Riordan
John Riordan (1902 –
August 28 ,1988 ) was an American mathematician and author of major early works incombinatorics , particularly "Introduction to Combinatorial Analysis" and "Combinatorial Identities". He worked most of his life at Bell Labs, from 1926 (a year after its foundation) until his retirement in 1968, when he was appointed professor emeritus at theRockefeller University .From [http://www.research.att.com/~njas/doc/interview.html 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. [ "The enumeration of rooted trees by total height," J. Australian Math. Soc. 10 (1969), 278-282.] "
