Douglas Brinkley

Historian Douglas Brinkley considers Ronald Reagan one of the top five American presidents of the 20th century. Brinkley is the editor of The Reagan Diaries.

Forced out of New Orleans after Katrina hit last year, historian Douglas Brinkley, a professor at Tulane University, soon returned. He helped with rescue efforts and immediately began the task of collecting oral histories of the catastrophe.

The result is his new book, The Great Deluge, which offers a multi-perspective account of the storm and its aftermath. Brinkley is the author of three other historical narratives, including Tour of Duty.

Historian and author Douglas Brinkley teaches at Tulane University and was displaced by Hurricane Katrina. He has since returned to New Orleans and begun to document the catastrophe by gathering oral histories -- he hopes to collect as many as 20,000 -- for a book, tentatively titled The Great Deluge.
