Stanley G. Weinbaum was born on April 4, 1902 and died of lung cancer on December 14, 1935, only 17 months after publishing his first story. During that time, he made an indelible mark on the field. Weinbaum Crater on Mars is named in his honor and in 2008, he received the Cordwainer Smith Rediscovery Award.
Weinbaum’s “The Worlds of If” was first published in the August 1935 issue of Wonder Stories, edited by Hugo Gernsback. Following Weinbaum’s death, it was included in Dawn of Flame: The Weinbaum Memorial Volume. Mort Weisinger reprinted the story in the March 1941 issue of Startling Stories and it was included in issue 1 of Fantasy, edited by Walter Gillings.
When Fantasy Press published A Martian Odyssey and Others, a collection of Weinbaum’s stories, “The Worlds of If” was included. Robert Silverberg selected it for Other Dimensions: Ten Stories of Science Fiction. Julie Davis included it in Science Fiction Monthly, in the July 1975 issue of the paperback series. When Ballantine published The Best of Stanley Weinbaum, the story was reprinted again.
