Many words have been written about Tom Watson, Jr., but perhaps none of them are better phrased or as significant as those written by the man himself. If you're interested in learning more about Watson -- his career, his thinking, his life -- two excellent sources are Watson's own:

A Business and its Beliefs: The Ideas That Helped Build IBM. New York: McGraw-Hill Book Co., Inc., 1963.

Father Son & Co.: My Life At IBM And Beyond. New York: Bantam Books, 1990. (Peter Petre, co-author)
