Albert Einstein is one of the most famous figures in history. He was a scientist known for his formula, E=MC(2).
Einstein was a vegetarian during the last year of his life, although he had supported the idea for a long time. In a letter to Max Kariel he said, "I have always eaten animal flesh with a somewhat guilty conscience," and soon after became a vegetarian.
Enstein's famous quote, "Nothing will benefit health or increase chances of survival on earth as the evolution to a vegetarian diet."
