The Hamburger Bun is a soft bread roll. By adding meat, lettuce, tomato and condiments to the sliced in half bun, you get a “hamburger”. The first person to serve a hamburger on a bun was most likely Oscar Weber Bilby, who served a ground meat patty on buns baked by his wife, but they were more similar to a roll and not necessarily a true Hamburger Bun. It is generally accepted that the modern Hamburger Bun was invented in 1916 by a cook named Walter Anderson. He is credited with creating the modern grill. Hamburger Buns are designed to be round yet flat. They are typically wider than they are tall, and can therefore more easily hold the hamburger patty and toppings, without adding too much extra height.
