About this person

In one isolated paper he introduced the important concept of error diffusion for rendering images, also called Floyd-Steinberg dithering. He pioneered in the field of program verification using logical assertions with the 1967 paper Assigning Meanings to Programs. This was a contribution to what later became Hoare logic. Floyd received the Turing Award in 1978.
