To distinguish myself from all the "presidential historians" out there, I have invented a new area of expertise: "presidential crisis historian." How a president confronts the gravest challenges of modern times, and how his decisions affect the rest of us, has been a recurring theme of my seven books.

One Minute to Midnight focused on possibly the gravest crisis ever, in October 1962, when John F. Kennedy stepped back from the nuclear brink at the last possible moment. The Unwanted looked at Franklin Roosevelt's handling of the Jewish refugee crisis that preceded the Holocaust. Six Months in 1945 examined how FDR and Truman negotiated the perilous transition from World War to Cold War. My latest book, King Richard: An American Tragedy, relates the Shakespearean tale of the self-made man who scrambled his way to the top only to see his dreams turn to nightmares because of tragic character flaws.

Before becoming an author, I was a journalist and foreign correspondent. After a stint in Rome as a correspondent for Reuters, and a tour of Africa, I lived in Yugoslavia during the twilight years of Marshal Tito. I moved to Poland for The Washington Post just in time to witness the extraordinary spectacle of workers rebelling against the "workers' state." I was the first western reporter to visit the Lenin shipyard in Gdansk in August 1980. As The Post's bureau chief in Moscow, I was standing in front of Boris Yeltsin in August 1991 when he climbed on a tank to face down Communist hardliners. In between these two events, I covered the imposition of martial law in Poland, the Chernobyl nuclear catastrophe, Gorbachev-Reagan summits, the Tiananmen uprising in China, and the 1989 revolution in Romania.

In addition to my work as a journalist and a historian, I have taught courses at the universities of Princeton, Michigan, and Georgetown, as well as American University. I also spent seven years at the United States Holocaust Memorial Museum where I organized conferences on the genocides in Rwanda and Bosnia, and researched and wrote The Unwanted. King Richard is my seventh book.
