Bio
Edna Ferber (August 15, 1885 - April 16, 1968) was an American novelist, short story writer and playwright. Her novels include the Pulitzer Prize-winning So Big (1924), Show Boat (1926; made into the celebrated 1927 musical), Cimarron (1930; adapted into the 1931 film which won the Academy Award for Best Picture), Giant (1952; made into the 1956 film of the same name) and Ice Palace (1958), which also received a film adaptation in 1960.

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, ethnic or otherwise.
Ferber's works often concerned small subsets of American culture, and sometimes took place in exotic locations she had visited but was not intimately familiar with, such as Texas or Alaska. She thus helped to highlight the diversity of American culture to those who did not have the opportunity to experience it. Some novels are set in places she had not visited. (wikipedia.org)
