What did Herb Peterson invent?

Herbert Ralph "Herb" Peterson (January 5, 1919 – March 25, 2008) was an American fast food advertising executive and food scientist most known for being the inventor of the McDonald's Egg McMuffin in 1972. The breakfast business that he pioneered with this item had grown to an estimated $4–5 billion in annual revenues for the fast food restaurant chain McDonald's by 1993.

McMuffin is a family of breakfast sandwiches sold by the international fast food restaurant chain McDonald's. The Egg McMuffin is the signature sandwich, which was invented in 1972 by Herb Peterson to resemble eggs Benedict, a traditional American breakfast dish with English muffins, ham, eggs and hollandaise sauce.

The first McDonald's corporate-authorized Egg McMuffin was served at the Belleville, New Jersey, McDonald's in 1972.
