An extract from Amazon.com about the author:
Emil Ludwig was born Emil Cohn in Breslau on 25 January 1881. Ludwig was apparently a pen name. His work on Napoleon was a best seller and made him famous. It secured his livelihood as a professional writer. He wrote many other books. Among others, he wrote biographies on Goethe, Bismarck, Lincoln, Hindenburg, Beethoven, Jesus, Cleopatra, Mussolini and Roosevelt, but he never hit another home run like he did with his book on Napoleon. He wrote his books in German but, due to the success of his book on Napoleon, they were translated almost immediately into English. In 1940, Ludwig moved to America, where he was able to live off the royalties to his works. After the war, he returned to Europe as a journalist and died there in Ascona, Switzerland on 17 September 1948.
