 hopping pat- tern on demand. Although the subject of the patent is secrecy and privacy, Hutchinson has stated [3] that he was aware of the advantage his concept could have for avoiding interference. The patent application, which received official review [74], was held under secrecy order by the U.S. Patent Office until 1950. As will soon be seen, Hutchinson's landmark patent was preceded in time, and eclipsed in human interest, by another true SR-FH-SS patent applica- tion filed by a rising Hollywood star! 2.1.5 Remote Control and Missile Guidance Interest in radio guidance dates back to the turn of the century. Notable pioneering efforts took place at the Hammond radio research Laboratory, a privately organized research group. Its founder, John Hays Hammond, Jr., an inventor whose development of radio remote control served as the basis for modern missile guidance systems," also " developed tech- niques for preventing enemy jamming of remote control and invented a radio-controlled torpedo " [75]. By 1914, he was actively exploring means to greatly minimize the possibility of an enemy determining the wave lengths used in the control of the craft and thereupon interfering with the control thereof" [76]. In the radio guidance of remote vehicles, Hammond was following in the footsteps of Adm. Bradley A. Fiske and of Nikola Tesla [77,p.iii]. (Note: See [44, ch. XXIX] for more background on Hammond, Fiske, and Tesla.) The efforts against jamming were, initially, Emerging Concepts pursued by Benjamin F. Miessner, Hammond's sole coworker during 1912, who had invented a primitive form of SS signaling [77, p. 32] which was quite likely the earliest to be thus transmitted in a peculiar way" [77, p. 65]. The Miessner-Hammond carrier broadening was incorporated into a mil- itary transmitter, which with its associated receiver (that additionally intro- duced amplitude-limiting action) was delivered to the U.S. Army in France just before World War I ended. There, Maj. Edwin H. Armstrong verified the Hammond system's ability to
