Which family founded the U.S. fast-food chain In-N-Out Burger in Baldwin Park, California, in 1948?

The Snyder family founded In-N-Out Burger in Baldwin Park, California, in 1948.

Harry Snyder and his wife Esther opened the first In-N-Out restaurant on October 22, 1948. Harry introduced a two-way intercom system so customers could order from their cars, an early drive-through innovation in Southern California.

Their sons Rich and Guy Snyder later led the business. In-N-Out became known for a deliberately limited menu, fresh preparation, and company-owned restaurants rather than franchising. The chain expanded gradually across selected western U.S. states.

The company is often confused with McDonald's because both began in Southern California and became famous for hamburgers. In-N-Out's founders were Harry and Esther Snyder, while McDonald's was founded by Richard and Maurice McDonald and later expanded nationally under Ray Kroc.
