The Oh Henry! bar was first introduced in 1920 by the Williamson Candy Company of Chicago, Illinois. There are many stories about how the name originated, including a legend that the bar was originally named after a boy who frequented the Williamson company, flirting with the girls who made the candy. The name is also said to be a homage to American writer O. Henry.
