    Biographical / Historical

    George Eustace Amyot Hallett, an aviation pioneer, aircraft engine developer, and inventor, devoted the major part of his adult life to aviation. He was born in England on May 9, 1890. His parents came to America when he was six months old, locating in San Diego, California. After finishing school, he worked as an apprentice for the Baker Machine Company in San Diego, specializing in the maintenance and repair of boat and automobile engines, while also taking a home study course in engineering.
    He became acquainted with two amateur San Diego aviation enthusiasts, Bernard F. Roehrig and Charles Walsh, who were experimenting with airplanes and teaching themselves to fly at Imperial Beach. The Roehrig machine had been built at Baker Machine Company, and Hallett began to help the two aviators make repairs and tune their engines. In 1910, Hallett made Glenn H. Curtiss’ acquaintance when Curtiss began to adapt North Island for use as a training base. Curtiss had rented a boat from Baker Machine to transport men and equipment. Soon, Curtiss made arrangements to borrow Hallett, which proved to be the start of a long association.
    Hallett was a member of the small Curtiss group who succeeded in making the first successful flights off the water in 1911. He was also involved in attaching a retractable wheel landing gear to their aircraft, which they called the Triad, the first successful amphibian. The same year Hallett accepted a position as the mechanic for Charles C. Witmer and the Curtiss flight exhibition team, later also serving over the next several years as the mechanic for other Curtiss team pilots. In 1914, Hallett received flight training, in anticipation of his role as the co-pilot of the flying boat America, planned for a trans-Atlantic flight attempt. The flight was abandoned due to the impending war in Europe.
    Hallett returned to North Island in 1914, supporting the Curtiss Model N that was to enter the Army competition trials there. This airplane was later modified and became the well known Curtiss JN during and after World War I. Late that year he left Curtiss and accepted a government position as the Army’s aviation mechanic at North Island, supervising engine overhaul and serving as a consultant on engine matters. He then developed a course of study for engine mechanics and developed a new method for investigating engine problems and failures. This led to his preparation of a book on the topic, which became a standard part of aviation ground school instruction.
    In 1917, after the declaration of war, Hallett was called to Washington and placed in charge of organizing mechanic’s schools for the Army Air Service at large. He also assisted colleges in adding his coursework, which, by then, had achieved national prominence. In 1918, he was commissioned a Major in the Army Air Service and was sent to Wright Field in Dayton, where he established the power plant and aeronautical repair departments. After the War, he was transferred to McCook Field, where he was placed in charge of the power plant branch. There, he established an engineering department and an engine test and development facility, which led to a number of innovations, particularly with engine superchargers.
    In 1922, Hallett resigned from the Army to become a research engineer and section head of the General Motors Research Laboratory in Detroit. His work at General Motors included laying the foundation for their very successful diesel engine program. Of note, he was a prominent member of the group that arranged for the moving of the Wright residence and workshop from Dayton to Greenfield Village, to become a permanent part of the Ford Museum at Dearborn.
    George Hallett retired from General Motors in 1937, moving first to Tucson, Arizona, where he lived for four years, following which he returned to the San Diego area, where he made his final home in La Mesa. During World War II, he served as a special consultant for Reuben H. Fleet and Consolidated Aircraft in San Diego. He continued to fly whenever possible, never lost his interest in things mechanical, and also enjoyed small cars and photography. Major Hallett served as Chairman of the Prudden Historical Library and Archives at what is now the San Diego Air & Space Museum, a position he held for a number of years, initially in 1963.
