Joseph Shaw (editor)

Joseph T. "Cap" Shaw (May 8, 1874 – August 2, 1952) was the editor of Black Mask magazine from 1926 to 1936.

Before becoming the editor of Black Mask, Shaw had worked as a newspaper reporter and as a soldier in World War I, attaining the rank of captain (Shaw's friends gave him the nickname "Cap"). Shaw was also a professional fencer, and even won an Olympic medal for fencing. Under his editorship, Black Mask published many works of crime fiction now recognised as classics of the genre, by authors such as Dashiell Hammett, Raymond Chandler, and Erle Stanley Gardner. Chandler greatly admired Shaw's ability to encourage Black Mask writers, claiming in a letter, "We wrote better for him than we could have written for anybody else."

Despite the critical and commercial success of Black Mask, Shaw was eventually fired from the magazine, succeeded by Fanny Ellsworth. Shaw then worked as a literary agent, though without notable success.

Shaw was a writer himself, producing short stories, novels, and articles.
