Final answer:
L. Frank Baum, the author of The Wizard of Oz, operated a newspaper in South Dakota known as The Aberdeen Saturday Pioneer before he found success as a writer.
Step-by-step explanation:
Before his success with The Wizard of Oz, Lyman Frank Baum, better known as L. Frank Baum, dabbled in the world of journalism in South Dakota. While living in South Dakota, Baum owned and ran a newspaper known as The Aberdeen Saturday Pioneer. This journalistic venture occurred well before he wrote his famous story that introduced readers to the magical land of Oz.
Baum's work in South Dakota as a journalist, including his ownership of The Aberdeen Saturday Pioneer, was a formative experience that occurred during the time period when the profession was undergoing significant changes nationwide, and publishers like Baum contributed to the vibrant local newspaper culture of the late nineteenth century.
