Dr. Dvorak, along with Dealey, Nellie Merrick, and Gertrude Ford, wrote the book Typewriting Behavior, which was published in 1936. The book, which has been out of print since then, is an in-depth report on the psychology and physiology of typing.
Dr. Dvorak was distantly related to the Czech composer Antonin Dvorak. It is worth noting that while the composer's name is pronounced /dvOrZAk/ (in SAMPA), August Dvorak's family in the U.S pronounces it as /dvOr{k/.
