J T McIntosh (1925-2008)
J. T. McIntosh was the pseudonym used by Scottish writer and journalist James Murdoch MacGregor, under which all of his SF writing appeared (with the exception of a single story). Born in Paisley, Scotland, in 1925, he began publishing science fiction in 1950 with 'The Curfew Tolls', which appeared in John W. Campbell's Astounding Science Fiction magazine. His first novel, World Out of Mind, appeared three years later, and he continued to write novels of interest over the next decade and a half, but ceased publishing work after 1980. He died in 2008.
