Wikipedia page about the Oh Henry! candy bar
Oh Henry! is a candy bar containing peanuts, caramel, and fudge coated in chocolate. It was first introduced in 1920 by the Williamson Candy Company of Chicago.
Legend has it that, Oh Henry! was originally named after an electrician who frequented the Williamson Candy Company, flirting with the girls who made the candy. The name is also said to be a homage to American writer O. Henry. However, there is no definitive explanation as to the exact origin of the name.
Another theory is that the candy bar was invented by a man named Tom Henry of Arkansas City, Kansas. Tom Henry ran a candy company called the Peerless Candy Factory, and in 1919 he started making the Tom Henry candy bar. He sold the candy bar to Williamson Candy Company in 1920, where they later changed the name to "Oh Henry!". Henry's family now runs a candy factory in Dexter, Kansas, and they sell "momma henry" bars, which are nearly identical to the original candy bar.
