Stanley Owen Green (22 February 1915 – 4 December 1993), known as the Protein Man, was a sandwich man who became a well-known figure in London, England, during the latter half of the 20th century.[1]<br />

For 25 years, Green patrolled Oxford Street in the West End, carrying a placard that advocated "Less Lust, By Less Protein: Meat Fish Bird; Egg Cheese; Peas Beans; Nuts. And Sitting," though the wording—and punctuation—changed slightly over the years. Arguing that protein made people lustful and aggressive, his solution was "protein wisdom," a low-protein diet for "better, kinder, happier people."[2] For a few pence, passers-by could buy his 14-page pamphlet, Eight Passion Proteins with Care, which reportedly sold 87,000 copies over 20 years, its front cover observing, "This booklet would benefit more, if it were read occasionally."[3]
