John Wanamaker (1838-1922) was an American merchant and religious leader, considered a pioneer in marketing and advertising. He is best known for founding Wanamaker's department store in Philadelphia, which was one of the first modern department stores. Wanamaker revolutionized retail by introducing fixed prices, money-back guarantees, and window displays. Imagine him as the Elon Musk of 19th-century retail.
