One of the most important contributors to the development of electronic music, as he worked at Bell Labs in the 1950s and was one of the first people to get sound out of a computer. He also helped develop the technology that went into the Yamaha DX7 - probably the most famous synthesizer of all time. The Max/MSP software is named after him and Miller Puckette (one of my crowning achievements was when Puckette briefly used a composition of mine as required listening in one of his classes).
