Before Marriott became synonymous with the hospitality industry, founder J. Willard Marriott owned and operated several root beer stands throughout the Washington D.C. area back in the 1920s. Decades later in 1957, the first Marriott hotel, the Twin Bridges Motor Hotel, opened in Arlington, Va. J. Willards’s eldest son Bill Jr. joined the company that same year, and became president in 1964, running more than 3,700 properties in 73 countries. His brother Richard took control of Host Marriott International – now Host Hotels and Resorts – in 1993, which owns more than 100 properties worldwide, including the Marriott Marquis New York and the Ritz-Carlton San Francisco. The Marriott brothers may have inherited a massive lodging operation, but together they have transformed their legacy into a multi-billion dollar hotel dynasty.
