From M. Michael Brady
The first proposal for a communications satellite in geosynchronous orbit is customarily attributed to author Arthur C. Clarke (8 September, p 50). Clarke’s 1945 proposal was predated by Hermann Noordung, the pseudonym of Captain Herman Potocnik of the old Austrian imperial army. Potocnik’s small monograph, Das Problem der Befahrung des Weltraums (The Problem of Space Travel), was published in Berlin in 1929 and reprinted in 1993 in Vienna.
