H. Beam Piper

Henry Beam Piper (March 23, 1904 – ) was an American science fiction writer. He wrote many short stories and several novels. He is best known for his extensive Terro-Human Future History series of stories and a shorter series of "Paratime" alternate history tales.

He wrote under the name H. Beam Piper. Another source gives his name as "Horace Beam Piper" and a different date of death. His gravestone says "Henry Beam Piper". Piper himself may have been the source of part of the confusion; he told people the H stood for Horace, encouraging the assumption that he used the initial because he disliked his name. On a copy of ''Little Fuzzy'' given to Charles O. Piper, Beam's cousin and executor, he wrote "To Charles from Henry." Provided by Wikipedia
