I've always loved historic buildings. I marvel at the workmanship and wonder what it looked like in the first days of being built. 

When I found out that developers wanted to knock down one of the most iconic buildings in NYC, I was driven to write the story of how a First Lady was moved to save Grand Central Terminal. The case went all the way to the Supreme Court. Today there is a special lobby dedicated to Jackie at the terminal.

Read about what Jackie did after she was out of the White House in the name of historic preservation. (May is National Preservation Month) in When Jackie Saved Grand Central.

Here's a list of the top 15 First Ladies. Do you agree? Who else would you add and why?
