Steinbeck was born on February 27, 1902, in Salinas, California. He was of German, English, and Irish descent. Johann Adolf Großsteinbeck (1828–1913), Steinbeck's paternal grandfather, was a founder of Mount Hope, a short-lived farming colony in Palestine that disbanded after Arab attackers killed his brother and raped his brother's wife and mother-in-law. He arrived in the United States in 1858, shortening the family name to Steinbeck. The family farm in Heiligenhaus, Mettmann, Germany, is still named "Großsteinbeck".
His father, John Ernst Steinbeck (1862–1935), served as Monterey County treasurer. John's mother, Olive Hamilton (1867–1934), a former school teacher, shared Steinbeck's passion for reading and writing. The Steinbecks were members of the Episcopal Church, although Steinbeck later became agnostic. Steinbeck lived in a small rural valley (no more than a frontier settlement) set in fertile soil, about 25 miles from the Pacific Coast. Both valley and coast would serve as settings for some of his best fiction. He spent his summers working on nearby ranches including the Post Ranch in Big Sur. He later labored with migrant workers on Spreckels sugar beet farms. There he learned of the harsher aspects of the migrant life and the darker side of human nature, which supplied him with material expressed in Of Mice and Men. He explored his surroundings, walking across local forests, fields, and farms. While working at Spreckels Sugar Company, he sometimes worked in their laboratory, which gave him time to write. He had considerable mechanical aptitude and fondness for repairing things he owned.
Steinbeck graduated from Salinas High School in 1919 and went on to study English literature at Stanford University near Palo Alto, leaving without a degree in 1925. He traveled to New York City where he took odd jobs while trying to write. When he failed to publish his work, he returned to California and worked in 1928 as a tour guide and caretaker at Lake Tahoe, where he met Carol Henning, his first wife. They married in January 1930 in Los Angeles, where, with friends, he attempted to make money by manufacturing plaster mannequins.
When their money ran out six months later due to a slow market, Steinbeck and Carol moved back to Pacific Grove, California, to a cottage owned by his father, on the Monterey Peninsula a few blocks outside the Monterey city limits. The elder Steinbecks gave John free housing, paper for his manuscripts, and from 1928, loans that allowed him to write without looking for work. During the Great Depression, Steinbeck bought a small boat, and later claimed that he was able to live on the fish and crabs that he gathered from the sea, and fresh vegetables from his garden and local farms. When those sources failed, Steinbeck and his wife accepted welfare, and on rare occasions, stole bacon from the local produce market. Whatever food they had, they shared with their friends. Carol became the model for Mary Talbot in Steinbeck's novel Cannery Row.
In 1930, Steinbeck met the marine biologist Ed Ricketts, who became a close friend and mentor to Steinbeck during the following decade, teaching him a great deal about philosophy and biology. Ricketts, usually very quiet, yet likable, with an inner self-sufficiency and an encyclopedic knowledge of diverse subjects, became a focus of Steinbeck's attention. Ricketts had taken a college class from Warder Clyde Allee, a biologist and ecological theorist, who would go on to write a classic early textbook on ecology. Ricketts became a proponent of ecological thinking, in which man was only one part of a great chain of being, caught in a web of life too large for him to control or understand. Meanwhile, Ricketts operated a biological lab on the coast of Monterey, selling biological samples of small animals, fish, rays, starfish, turtles, and other marine forms to schools and colleges.
Between 1930 and 1936, Steinbeck and Ricketts became close friends. Steinbeck's wife began working at the lab as secretary-bookkeeper. Steinbeck helped on an informal basis. They formed a common bond based on their love of music and art, and John learned biology and Ricketts's ecological philosophy. When Steinbeck became emotionally upset, Ricketts sometimes played music for him.
