Morgan Andrew Robertson (September 30, 1861 – March 24, 1915) was a well-known American author of short stories and novels and the self-claimed inventor of the periscope. He was the son of Andrew Robertson, a ship captain on the Great Lakes, and Amelia (Glassford) Robertson.
Morgan went to sea as a cabin boy and was in the merchant service from 1866 to 1877, rising to first mate. Tiring of life at sea, he studied jewelry making at Cooper Union in New York City and worked for 10 years as a diamond setter. When that work began to impair his vision, he turned to writing sea stories, placing his work in such popular magazines as McClure's and the Saturday Evening Post.
