Dorothy McIlwraith (1891-1976) inherited Weird Tales in 1940 when Farnsworth Wright left and died shortly afterwards. McIlwraith was a graduate of McGill University in Ontario. After graduating in 1914, she moved to New York and worked for Doubleday. She became editor of Short Stories in 1936 after being an assistant on the magazine. Two years later Short Stories Inc. bought Weird Tales, and Dorothy was its editor until the magazine folded in 1954.
McIlwraith’s Weird Tales is not the Golden Age WT. The owners wanted a smaller scope of fiction so the Sword & Sorcery was dropped. Later on Weird Tales became almost a kind of Science Fiction magazine. Despite this, authors such as Ray Bradbury, Richard Matheson and Joseph Payne Brennan debuted their work. Some of the old gang, like Manly Wade Wellman, Robert Bloch, August Derleth and Seabury Quinn carried as before. The days of Lovecraft-Howard-Smith were gone but Margaret St. Clair, Dorothy Quick, Mary Elizabeth Counselman, Carl Jacobi and Fritz Leiber had arrived.
It shouldn’t be any surprise that the artists that illustrated Short Stories would appear in Weird Tales and vice versa, though to a lesser degree. Fred Humiston is a good example. For many years, he illustrated half of each issue of Short Stories along with Edgar Wittmack.
Going the other way, Boris Dolgov and Lee Brown Coye did a couple of covers for Short Stories.

A. R. Tilburne did some of the worst Weird Tales illos but his many covers for Short Stories are quite good, often featuring animals.
