The Oh Henry Bar is a straightforward, delicious candy bar with a somewhat less-than-straightforward history....
Unlike Snickers, which was named after Forrest Mars' beloved racehorse, no one is 100% certain where the name "Oh Henry" came from.
Theories abound, but one thing that almost everyone agrees upon is that this is a delicious candy bar and has been for close to 100 years. And no, this candy bar is not named after the baseball great Hank Aaron.

Lore has it that the name was derived from that of a randy young man who made frequent visits to the original manufacturers – the Williamson company – less for sugary sweets and more to flirt with the eye candy who worked on the assembly line.
This leaves us to assume that the young man’s name was -- you guessed it -- HENRY!
But certain proof eludes us.
Perhaps a more credible theory is that the candy bar was named after the owner of the now-defunct Peerless Candy company.
The owner's name was Tom Henry, and in a vainglorious move, he created the Tom Henry Bar.
It was a short-lived venture as he sold the rights to the candy bar in 1920 to Williamson Candy, which changed the name to Oh Henry. 
O' Henry was also one of the first examples of “guerrilla marketing” as an employee of Williamson Candy Company, who was determined to make the Oh Henry Bar famous.
Lacking the funds to launch a full frontal Madison Avenue advertising campaign, this wily salesman had bumper stickers printed with only two words – Oh Henry.
Curiosity didn’t kill the cat, and this candy bar quickly made a name for itself.
The candy bar is also sold in Canada, with the difference being a "chocolately" coating rather than milk chocolate.
Things remained much the same for close to 65 years until 1984, when Nestle acquired the rights to distribute Oh Henry in the United States, but, alas, not everything lasts forever.
In 2018, Nestle sold the rights to Ferrara Pan, and the candy bar has curiously disappeared from the shelves.
As of October 2019, rumor had it that this beloved candy bar was discontinued, but, alas, it was only short-lived as they are now available and still using their almost 100-year-old time-tested formula!
