By Rick HowlettPulitizer Prize winning author T.J. Stiles will speak this week at the Louisville Free Public Library.Stiles won the 2010 Pulitzer for his biography of industry tycoon Cornelius Vanderbilt. He says he decided to pursue the project in part because there had never been a major biography written about Vanderbilt."The length of his life is just remarkable. He was born in 1794, during the presidency of George Washington. When he died in 1877, Grant was president, Reconstruction had come to an end and Vanderbilt had actually made deals personally with John D. Rockefeller," Stiles said last week in a WFPL interview. Stiles will speak and answer at the Louisville Free Public Library Wednesday at 7:00pm. The event is free but tickets must be obtained from the library.
