The In-N-Out founders

Harry Snyder (September 9, 1913 – December 14, 1976) was a Canadian businessman. He co-founded In-N-Out Burger along with his wife Esther Snyder. 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. Born in Vancouver to Dutch immigrants Hendrick and Mary Snyder, Harry Snyder grew up in Seattle and Santa Monica. He would work odd jobs to support his family. During World War II, he worked several desk jobs for the U.S. Navy due to his perforated ear drum. After the war ended, he worked as a caterer in Fort Lawton where he met his wife Esther Johnson.[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. In-N-Out is described as California's first drive-through. By the mid-1950s, the chain had expanded to six stores in the Los Angeles area. By the time of Snyder's death in 1976, the company had expanded to 18 stores.[2]

Snyder was born and raised in Sorento, Illinois, as the fifth of eight children (seven daughters, one son) to parents Orla and Mabel Johnson. She attended Greenville College and graduated from Seattle Pacific University with a bachelor's degree in zoology.During In-N-Out's early years, Snyder managed all of the company bookkeeping herself, creating thousands of pages of handwritten notes and accounts.

From January 2000 until her August 2006 death, Snyder served as the company's president

She met Harry Snyder in 1947, while working at a restaurant in Seattle; the two were married the following year and moved to Baldwin Park, California.[2] By the late 1950s, the couple had moved to a larger house in the nearby city of San Dimas, California.

Esther and Harry Snyder had two sons: Guy (1951-1999) and Rich Snyder (1952-1993) and one granddaughter from their first son Guy: Lynsi (born 1982). Esther outlived her husband, who died in 1976 from lung cancer and both of their sons, one of whom died in a plane crash and the other of a drug overdose.
