This week's question was: What is the name of
the type of gun that Colonel Custer left behind when he set out for the Battle
of Little Big Horn? This gun is also where a common slang term for a gun came
from.
The answer is the Gatling gun, named
after Richard Jordan Gatling. The
question (and answer) were found on p. 105 of The New Dictionary of Eponyms by Morton
Freeman. The book was published by
Oxford University Press in 1997.
