Snyder was one of the first people to develop the idea of a drive-through hamburger restaurant, where customers could order their food via an intercom.
During World War II, he worked several desk jobs for the U.S. Navy due to his perforated ear drum.
[1] Snyder and his wife opened the first In-N-Out Burger on October 22, 1948, in the Los Angeles suburb of Baldwin Park, California.
Early in their marriage, the Snyders lived in Baldwin Park, across the street from the original In-N-Out hamburger stand.
By the late 1950s, the family had moved to a larger house in the nearby city of San Dimas, California, where Snyder would spend the rest of his life.
