Sharp, Robert George

(1908-1987) UK author, initially of crime thrillers under his own name, two of these – The Cry from the Ether (1934) and Horror Castle (1936) – being of some genre interest. Most of his later work was relatively routine sf as by Jon J Deegan, (possibly a House Name, though Sharp may have used the name exclusively), initially for the Old Growler series, Reconnoitre Krellig II (1951), which comprises a one-story issue of Authentic Science Fiction (one-story issues are treated as books in this encyclopedia). The series, which is Space Opera, follows the adventures of a three-man survey team across the galaxy. Sharp was also the author of the Corridors of Time sequence, also as by Deegan. [JC]
