Dennis Ritchie (often referred to as dmr) was an influential American computer scientist, best known for his work on UNIX and the C programming language - both produced in collaboration with Ken Thompson.
He attended Harvard, where he received an undergraduate degree in 1963, and a doctoral degree in 1968. He went to work at Bell Labs in 1967, joining the Computing Sciences Research Center; he spent the rest of his career at the Labs, and its descendants. In 1968, he was part of the Bell team which joined the Multics project; after Bell pulled out of Multics, he and Thompson eventually fell into UNIX and C.
