Jim Turner

Mamta Popat/Arizona Daily Star

Saturday is the city of Tucson's 236th birthday. To celebrate, the Arizona Daily Star has invited local historian Jim Turner to answer your questions about the Old Pueblo.

Turner moved to Tucson in 1951. As a child, his family visited many of Arizona's historical sites, and this is when his fascination with the state's history began. He is retired from the Arizona Historical Society and is now a freelance lecturer and "Roads Scholar" for the Arizona Humanities Council, writer of "Arizona: A Celebration of the Grand Canyon State" and an editor who teaches and gives tours for Pima Community College.

Get your questions ready and go to azstarnet.com at noon Friday for a live chat with Turner.

HOW MUCH DO YOU KNOW ABOUT TUCSON HISTORY?

Here are a few sample questions provided by Jim Turner to test your Tucson knowledge:

• Why does no one know when the first Spanish soldiers began to live in what is now Tucson?

• When the townspeople received a federal grant to build the University of Arizona, what did they want to spend the money on instead?

• Why did California Column troops duck to the side of their horses and shoot at the rooftops when they first arrived in Tucson in 1862?
