William Smith (January 2, 1924 in Blythe, California - October 1, 1980; age 56) was an American-born farmer who came to Hopper Island with his wife Madeleine in 1948. A failed farmer, Smith was desperate to leave the United States after World War II and to start over again somewhere else. Joshua Hunter invited him to Hopper Island.

Madeleine and William remained childless. She died in 1876; William died four years later.
