James Murdoch MacGregor, (14 February 1925 – 2008) was a Scottish journalist and author best known for writing science fiction under the pen name J.T. McIntosh.
Born in Paisley, Renfrewshire, Scotland, but living largely in Aberdeen, MacGregor used the pseudonym McIntosh (along with its variants J. T. MacIntosh, and J. T. M'Intosh) as well as "H. J. Murdoch", "Gregory Francis" (with Frank H. Parnell), and "Stuart Winsor" (with Jeff Mason) for all his science fiction work, which was the majority of his literature, though he did publish books by his own name. His first story, "The Curfew Tolls", was published in the magazine Astounding Science Fiction during 1950, and his first novel, World Out of Mind, was published during 1953. He did not publish any work after 1980. He died during 2008.
Along with John Mather and Edith Dell, he is credited for the screenplay for the colour feature movie Satellite in the Sky (1956).
During 2010 the National Library of Scotland purchased his literary papers and correspondence.
John Clute writes that "McIntosh never lost the vivid narrative skills that made him an interesting figure of 1950s sf, but his failure to challenge himself or his readers in his later career led to results that verged on mediocrity. His early work warrants revival".
