Dennis Ritchie September 9, 1941 (age 70)

K said if stranded on an island with only one programming language it would have to be C.

Ritchie is best known as the creator of the C programming language and a key developer of the Unix operating system, and as co-author of the definitive book on C, The C Programming Language, commonly referred to as K&R (in reference to the authors Kernighan and Ritchie).
