It's a sad day for Fast Food history enthusiasts. Herb Peterson, the genius behind the Egg McMuffin passed away today. The 89-year old former ad man dreamed up the sandwich as a way to open up a whole new area of business for Ray Kroc and company- breakfast! Before the McMuffin, McDonald's lived off of its lunch and dinnerÂ operation. Peterson was also the brains behind McDonald's original slogan "Where Quality Starts Fresh Every Day," and I'm sure his enthusiasm for the Golden Arches will certainly be missed.
