William Seward Burroughs III (July 21, 1947 – March 3, 1981) was an American novelist, also known as William S. Burroughs Jr. and Billy Burroughs. He bears the name of both his father and his great-grandfather, William Seward Burroughs I, the original inventor of the Burroughs adding machine. He wrote three novels, two of which were published as Speed (1970) and Kentucky Ham (1973). His third novel, Prakriti Junction, begun in 1977, was never completed, although extracts from it were included in his third and final published work Cursed From Birth.
