Edward Groff Conklin (September 6, 1904 – July 19, 1968) was an American science fiction anthologist. He edited 40 anthologies of science fiction, one of mystery stories (co-edited with physician Noah Fabricant), wrote books on home improvement and was a freelance writer on scientific subjects as well as a published poet. From 1950 to 1955, he was the book critic for Galaxy Science Fiction.
Born in Glen Ridge, New Jersey, Conklin was educated at Dartmouth College and Harvard University, and graduated from Columbia University in 1927. He drifted restlessly through a series of jobs in the 1930s and 1940s, working for several government agencies during WWII. He was a book editor for Robert M. McBride & Co. and did public relations work for the Federal Home Loan Bank, the Office of Strategic Services, the Department of Commerce, the National Cancer Institute and the American Diabetes Association. He was also a former scientific researcher for the N.W. Ayer & Son advertising agency.
It was as an editor of fiction that Conklin found his niche, beginning as early as 1930. At the age of 26, while employed as an assistant manager at New York's Doubleday Bookstore, he arranged for the hardcover publication of a story from The Smart Set Magazine (November 1913), reprinting "A Flood" by the Irish writer George Moore in a limited edition of 185 signed copies. Four years later, Conklin and Burton Rascoe published The Smart Set Anthology (1934, reissued as The Bachelor's Companion in 1944), the first collection of stories from that literary magazine.
Conklin's interest in short fiction continued with the 1936 publication of The New Republic Anthology: 1915-1935, edited with Bruce Bliven. The following year, he married the former Lucy Tempkin on October 1. During the next decade, he wrote books about subways, rental libraries and home construction, in addition to poetry and numerous magazine articles.
