Robert Conroy is the author of three alternate history novels, 1901, 1862, and 1945.

His first novel, 1901, deals with a German invasion of Long Island. His second novel, 1862, is based on what would have happened had England entered into the American Civil War on the side of the Confederacy. His most recent novel, 1945, deals with what would have occurred if the Japanese had not surrendered at the end of World War Two and a land invasion of the Japanese Home Islands was required.

Conroy has earned praise for his meticulous research and the historical accuracy he brings to his work. While many of the characters in his novels are historical figures, the character development for these as well as the fictional characters is also quite remarkable.

Conroy is a semi-retired business and economic history teacher living in suburban Detroit. He and his wife, Maureen, have one daughter, Maura.
