Michael Francis Flynn (December 20, 1947^[1] – September 30, 2023) was an American science fiction author. Nearly all of Flynn's work falls under the category of hard science fiction, although his treatment of it can be unusual since he applied the rigor of hard science fiction to "softer" sciences such as sociology in works such as In the Country of the Blind. Much of his short fiction appeared in Analog Science Fiction and Fact.^[2]
