” Louis Sachar (/ˈsækər/ SAK-ər; born March 20, 1954) is an American writer of children’s books. He is best known for the Wayside School series and Holes. Holes won the 1998 U.S. National Book Award for Young People’s Literature and the 1999 Newbery Medal for the year’s “most distinguished contribution to American literature for children”. In 2012 it was ranked number six among all-time children’s novels in a survey published by School Library Journal.
After graduating high school, Sachar attended Antioch College for a semester before transferring to the University of California, Berkeley, during which time he began helping at an elementary school in return for college credit. Sachar later recalled,
Sachar graduated from UC Berkeley in 1976 with a degree in Economics and began working on Sideways Stories From Wayside School, a children’s book set at an elementary school with supernatural elements. Although the book’s students were named after children from Hillside and there is a presumably autobiographical character named “Louis the Yard Teacher,” Sachar has said that he draws very little from personal experience, explaining that “….my personal experiences are kind of boring. I have to make up what I put in my books.” https://en.wikipedia.org/wiki/Louis_Sachar
