Indiana limestone is used in buildings and monuments throughout the country. The Pentagon, the United States Holocaust Memorial Museum, and the Empire State Building were all built with Indiana limestone.
Add the tower of The University of Texas at Austin's Main Building to that list. Completed in 1937, the famous tower is entirely faced with Indiana limestone.
Other famous Hoosiers include: Michael Jackson (Gary), Janet Jackson (Gary), James Dean (Marion), Florence Henderson (Dale), John Mellencamp (Seymour), Shelley Long (Fort Wayne), Jim Davis/Garfield the cat (Muncie), David Letterman (Indianapolis), Steve McQueen (Beech Grove), violinist Joshua Bell (Bloomington), Red Skelton (Vincennes) and Colonel Sanders, the founder of Kentucky Fried Chicken (Henryville).
I'd like to add Curt McDowell and Melinda McDowell (both born and raised in Lafayette) to your venerable list!
