Anyone know who made the first V-twin engine for the motorcycle?

First correct answer gets the points. Please, no profanity and no links. Just short and sweet answers.
HINT: The guy made airplanes later in life. With that engine he set the world's record at the time.
Update: For information purposes. THIS IS NOT HOMEWORK. THIS IS TRIVIA TO SEE IF ANY ONE ELSE KNOWS THE NAME OF THE MAN WHO MADE THE ENGINE. DON'T BE A JERK AND A ***! Thank you!
Update 2: OOPS! It was not Harley or Davidson. The engine was made before they went into business.
