Who wrote the book "My Life on the Plains"?

George Armstrong Custer, (born December 5, 1839, New Rumley, Ohio, U.S.—died June 25, 1876, Little Bighorn River, Montana Territory), was a U.S. cavalry officer who distinguished himself in the American Civil War (1861–65) but later led his men to death in one of the most controversial battles in U.S. history, the Battle of the Little Bighorn.

George Armstrong Custer has been called a "media personality", and he valued good public relations and used the print media of his era effectively. He frequently invited journalists to accompany his campaigns (one, Associated Press reporter Mark Kellogg, died at the Little Bighorn), and their favorable reporting contributed to his high reputation, which lasted well into the latter 20th century.

Custer enjoyed writing, often writing all night long. He wrote a series of magazine articles of his experiences on the frontier, which were published in book form as "My Life on the Plains" in 1874.
