In 1933 he became a Doctor of Jurisprudence. While working as a senior staff member in Albert Speer"s Ministry of Armaments, he saved the lives of many Jews. In 1945 Keller organized an anti-Nazi resistance group in Berlin which briefly ran a pirate radio station and which planned a rather foolhardy attempt on Hitler"s life.
He was caught and sentenced by the Nazi Volksgerichtshof ("People"s Court") to death by hanging.
There, Keller was at the end of April 1945 liberated by American troops of the 69th Infantry Division. After the Second World War Keller worked as a journalist and a science writer in Hamburg.
He has worked for Nordwestdeutscher Rundfunk (The North West German Broadcasting Corporation) and for such papers and magazines as Die Welt, Die Zeit, Stern, and Neue Illustrierte. He sometimes used the pseudonym Norman Alken.
In 1955 he published "The Bible as History", his best-known and most successful book, which correlated the text of the Bible with the results of archaeological diggings in the Middle East, providing, according to Keller, a confirmation for the Bible"s veracity which was not dependent on religious faith.
Among others, it was successfully translated into Hebrew at a time when cultural relations with Germany were far from taken for granted in Israel. The "Davar" Labour daily in Tel Aviv in 1958 distributed free copies of Keller"s book to its subscribers. Later books by Keller dealt with the history and culture of the Etruscans.
