Frederick Orlin Tremaine (January 7, 1899 – October 22, 1956) was an American science fiction magazine editor, most notably of the influential Astounding Stories. He edited a number of other magazines, headed several publishing companies, and sporadically wrote fiction. Biography F. Orlin Tremaine was part of an old Cornish American family. He had two brothers, DeWitt Carlton (1900–65) and Nelson Dowd Tremaine (1907–71), and one sister, Alice Leila M. Tremaine (1912–1998). He was a veteran of World War I. In 1921, he graduated with a B.O. degree from the College of Arts and Sciences, Valparaiso University, Indiana. At Valparaiso, he was active in his fraternity, participated in drama, and worked on the weekly school newspaper, The Torch. In 1932, he married Vera Evangeline Kurtz (1905–92). They were no longer together by 1940. He was a member of the Mystery Writers of America, the Washington (D.C.) Press Club and of the Sons of the American Revolution. He died at Westmount Sanatorium, Glen Falls, New York, after a long illness, age 57, survived by two brothers and a sister. Writing, editing, and publishing career During his junior year at Valparaiso, in the spring term, 1920, Tremaine was News Editor of the weekly school newspaper, The Torch. He served as Editor-in-Chief during his senior year of 1920–21. His first job, post-graduation, was on the staff of a New York City newspaper. In late 1922, he was associate editor for The Eastern Underwriter in NYC. He moved on to the Macfadden magazine conglomerate. In May 1923, he was the managing editor of Macfadden's Brain Power and Beautiful Womanhood. On June 1, 1923, he became editor of the prestigious Metropolitan Magazine (retitled Macfadden Fiction-Lover's Magazine for the October 1924 issue). In early 1924, he became editor of the flagship title True Story Magazine. He also claimed credit for laying out the first issues of True Romances, True Detective, and True Experiences. Tremaine later credited John R. Coryell as a strong influence: "Coryell, approaching eighty of years of age, was fiction or story editor of the Macfadden Publications a quarter of a century ago when I first became an editor of a national magazine, and he taught me more about stories, simplicity of approach, and the technique of modern writing than any other person, before or since." Later in 1924, he departed to become editor of The Smart Set, a tenure that lasted until mid-1926. A
