Davenport, Iowa is not a hotbed of celebrity activity. In fact, it's probably best known as the birthplace of John Deere and as a stop on the Mississippi River. However, one famous person did die in Davenport: Wyatt Earp.
Earp was born in Illinois in 1848, but moved to Iowa as a young child. He grew up in Pella and then spent some time in Kansas before moving to Davenport in 1874. He worked as a riverboat gambler and also operated a faro game at the Davenport House Hotel.
While Earp is most famous for his involvement in the gunfight at the O.K. Corral, he actually died of natural causes in 1929 while living in Los Angeles. He was 80 years old.
