Captain Lehmann's last book, "Zeppelin: The Story of Lighter-than-air Craft", was being translated by Leonhard Adelt, who was on board with Lehmann as a guest during the "Hindenburg"s last flight. The book had recently been published in German when the "Hindenburg" was destroyed. The English translation, completed by Jay Dratler, was published later in 1937 with a preface and closing chapter by the American airship captain Charles E. Rosendahl, who had interviewed Lehmann on his deathbed.
