Otto J. M. Smith (1917–2009) was an educator, inventor and author in the fields of engineering and electronics.
[3]" It was for this achievement that he was listed in InTech's "Leaders of the Pack" as one of the 50 most influential industry innovators since 1774.
Other notable early achievements of Dr. Smith were the purchase in 1951 of the rights to his sine-function generator, U.S. patent 2,748,278 by Hewlett Packard, and in 1958, the publication of a technical textbook on feed back control systems by McGraw-Hill.
More recently Smith developed methods of running three-phase induction motors on single-phase power.
That portion of the US patent database that is searchable by name (since 1975) lists 15 inventions by Smith in these fields.
