Jack Warner Schaefer (November 19, 1907 – January 24, 1991) was an American writer known for his Westerns. His best-known work is Shane, which was made into the film Shane, and the short story "Stubby Pringle's Christmas" (1964).
Jack Schaefer was born in Cleveland, Ohio, and was the son of a German American attorney. In 1929 he graduated from Oberlin College with a major in English. From 1929-1930 he attended graduate school at Columbia University, but left without completing his Master of Arts degree. He then went to work for the United Press. In his long career as a journalist, he would hold editorial positions at many eastern publications.
Schaefer's first success as a novelist came in 1946 with his novel Shane, set in Wyoming. Though Schaefer himself had never been in the western United States, he continued writing westerns, selling his home in Connecticut and moving to Santa Fe, New Mexico in 1955.
In 1975 Schaefer received the Western Literature Association's Distinguished Achievement award.
He died of heart failure in Santa Fe in 1991. Schaefer was married twice, his second wife moving to Santa Fe with him.
