E.J. Rath was the pseudonym of J. Chauncey Corey Brainerd and his wife Edith Rathbone Brainerd. Chauncey and Edith, who were both writers, went on to collaborate on a number of stories together under the pen name E.J. Rath. Chauncey was a veteran of the Spanish-American War. At the time of his death he had been the Washington bureau chief for the Brooklyn Eagle for over ten years. They were married on June 4, 1903.
While watching a movie one snowy night in Washington, DC, Chauncey Corey Brainerd and his wife Edith were killed when the flat roof of Crandall's Knickerbocker Theatre collapsed under the weight of over two feet of heavy snow. More than 200 other moviegoers and theater employees were killed or injured on that night during what became known as The Great Knickerbocker Storm of 1922.
