Samuel Klein (15 November 1923 – 20 November 2014) was a Polish-Brazilian business magnate and philanthropist who founded the Casas Bahia chain of department stores in Brazil, building them into the top retailer in the country. This along with his tendency to use massive warehouses for his goods, including the largest single warehouse in South America, led him to be known in the 1990s as the "Sam Walton of Brazil". Following his death in 2014 Klein has faced numerous accusations of sex trafficking, rape, and exploitation of minors.
