Walter Diemer was the first person to invent bubble gum even though he was an accountant by trade.
He played around with gum recipes in his spare time.
After discovering the candy, he sold it to mom and pop shops around the country and they sold out in a day.
However, he didn’t patent the invention, and copycats popped up all over the place, resulting in intense competition.
He never received royalties for the invention.
