Rhodes Scholar, historian, and bestselling author Walter Isaacson began his distinguished career as a journalist -- first for London's Sunday Times, then for The Times-Picayune/States-Item, published in his hometown of New Orleans. He joined Time magazine in 1978, working his way up from political correspondent to managing editor in a little less than two decades. He served for two years as chairman and CEO of the cable TV news network CNN; then, in 2003, he became president of the Aspen Institute, an international nonprofit organization "dedicated to fostering enlightened leadership and open-minded dialogue." In the wake of Hurricane Katrina, he was appointed vice-chairman of the Louisiana Recovery Authority, and he serves on a number of policy-making boards and councils.

In literary circles, Isaacson is best known as the writer of magisterial biographies, scholarly and meticulously researched, yet immensely entertaining. His first book, however, was a collaborative effort. Co-written with award-winning journalist Evan Thomas, and published in 1986, The Wise Men: Six Friends and the World They Made explores the lives of six men who shaped government and public policy in the years following WWII. Examining an era too recent to be called history and too distant to qualify as current affairs, the book received mixed reviews but was universally praised for its ambitious scope and elegant style.

Isaacson's subsequent biographies, all solo efforts (and all critically acclaimed), have chronicled the lives of such disparate figures as Henry Kissinger, Benjamin Franklin, and Albert Einstein. He explains what has drawn him to such widely divergent subjects -- men, who on the surface would appear to have very little in common: "I like writing about people with interesting minds. I try to explore the various aspects of intelligence: common sense, wisdom, creativity, imagination, mental processing power, emotional understanding, and moral values. Which of these traits are the most important? How do they make someone an influential or significant or good person?"
