Edna Ferber first gained success with these stories and later went on to write Show Boat, Giant and other well known books.

Edna Ferber (1885-1968) was an American novelist, short story writer and playwright. Her novels were especially popular and included the Pulitzer Prize-winning So Big (1924), Show Boat (1926; made into the celebrated 1927 musical), Cimarron (1929; made into the 1931 film which won the Academy Award for Best Picture), and Giant (1952; made into the 1956 Hollywood movie). 

Ferber's novels generally featured strong female protagonists, along with a rich and diverse collection of supporting characters. She usually highlighted at least one strong secondary character who faced discrimination ethnically or for other reasons; through this technique, Ferber demonstrated her belief that people are people and that the not-so-pretty people have the best character.
