Fredrick Frances Gerard (1823 – 1913) was a frontiersman, army scout, and civilian interpreter for George Armstrong Custer's 7th U.S. Cavalry during the Little Bighorn Campaign. Fred Gerard was a trader at Fort Berthold in the Dakota Territory and was for a time married to an Indian woman, the sister of a warrior named Whistling Bear. Gerard was hired by Lieutenant Colonel Custer to serve at Fort Abraham Lincoln as an interpreter for his Arikara "Ree" scouts, as he was very familiar with the language from his years as a trader. He had lived in Indian country for 31 years at the time and had been involved in several battles.
