Stanley Owen Green , known as Protein Man, became a well-known figure in central London, England, during the latter half of the 20th century.
Every day for 25 years, from 1968 until his death, Green paraded up and down Oxford Street in the central shopping district, carrying a placard that famously recommended "Less Passion from Less Protein: Less Fish Meat Bird Cheese Egg; Peas Beans; Nuts and Sitting."
