Шаблон:Short description Шаблон:Infobox scientist Elise (aka E'Lise) Frances Harmon (3 September 1909 – 6 March 1985 in Santa Clara County, California) was an American chemist and biologist by education and engineer by practice who invented several technologies in the emerging printed circuit board industry in the 1950s that allowed efficient printing of circuit elements on plastic substrate and continued making significant engineering innovations in circuit miniaturization into the 1970s.  She also conducted critical research on the performance of electrical equipment in aircraft under extreme conditions that enhanced aircraft performance in World War II.

Early life and education

Harmon graduated from Marshall High School in Marshall, Texas in 1927.

She earned a Bachelor of Science in chemistry in 1931 from North Texas State College (now University of North Texas) in Denton TX, a Master of Science in biology from the University of Texas in 1938, and took advanced coursework at several institutions. Harmon did post-graduate work at several institutions. Subjects she pursued included engineering at George Washington University, and polymer chemistry, mathematics, and mechanical engineering at the University of Maryland, College Park.

In June 1930, while a student, she was elected president of the W.N. Masters Chemical Society, a student organization she joined as a freshman in 1927, sponsored by Wallace Newton Masters (1864–1943), founder of the chemistry department in 1910.

Career highlights

Research and Development

From 1942–51, Harmon worked first in the United States Naval Research Laboratory's Aircraft and Electrical Division, then in the Heat and Power and Ordnance Divisions at the National Bureau of Standards in Washington, D.C. During World War II at the Naval Research Laboratory and later in the Heat and Power Division, she worked on engineering problems such as temperature range in aircraft electrical equipment, high altitude carbon brush performance in aircraft motors and generators and the action of lubricants in high-speed bearings.  Her work allowed aircraft motors and generators to operate safely at higher altitudes.   In the Ordnance Division she performed engineering research on proximity fuses and guided missiles.  She also designed, placed into operation, and tested equipment for the industrial production of printed circuits for military applications.

In 1952, she moved to the Aerovox Corporation, headquartered at Plant 2 in New Bedford, Massachusetts. In the 1970's, as head of Aerovox Corporations's printed circuit activities, she directed the research, development and pilot plan procedures for an entirely new method of printed circuitry and printed circuit components.  One of Harmon's major contributions to the field was the development of a hot die stamp method to create printed circuits in which silver conductors were infused on thermoplastics and thermosetting materials. She and Philip J. Franklin (né Philip Jacquins Franklin; 1909–1979) were awarded a patent in 1953 for this technological breakthrough. Harmon also researched the action of grease and lubricants in high speed ball bearings.

From 1957 to 1962, Harmon worked for the American Bosch Arma Corporation in Garden City, New York.  As senior engineer, she developed microminiaturization research and development programs related to advanced computers.  She liaised with the Manufacturing Department on Arma’s Inertial Guidance System for the Atlas ICBM and focused on microminiaturization in extraterrestrial vehicles and telemetry.

From 1962–1970, she was a senior engineer for Autonetics, a division of Rockwell International Corporation in Anaheim, California, where she was responsible for advanced technology for the fabrication of multilayer circuit boards for the Minuteman program.  This included developing and testing a specific micro-miniature circuit fabrication and packaging technology.

Consulting

She started Harmon Technical Consultants in 1970 and provided her expertise to numerous national and international corporations in the areas of printed circuits and multilayer board production problems.  Her clients included commercial printed circuit board producers such as Magnavox, aerospace companies Raytheon and Honeywell, and international clients such as Nippon Aviatronics.

Teaching

Harmon taught chemistry, physics, and biology at the Brownsville Junior High School from about 1934 to 1937. She later taught those subjects at Texas Junior College, the University of North Texas, and University of Texas at Austin.

Awards and honors

Harmon was awarded the 1956 Society of Women Engineers Achievement Award for her specialty in printed circuits. Harmon was awarded the 1968 IPC President's Award, honoring those who made the most significant contributions to IPC programs during the term of office of each departing IPC president

Death

Harmon died March 6, 1985, in Santa Clara County, California, while a resident of Redwood City, California. She is buried in Section P, Block 35, Grave 1 of the IOOF Cemetery, Denton, Texas, next to her mother, Geoffie Harmon (1887–1931), in Grave 2, and brother, Hamlett Stephen Harmon (1913–1997), in Grave 3. The three grave sites were purchased in 1931 by her father, George Herbert Harmon (1881–1957).

Family

Harmon had a brother and a sister. Her brother Ham Harmon, played professional football with the Chicago Cardinals in 1937 for one season. Her sister Ann Ferrari, participated in the Salk Polio Vaccine field trail, and served as Instructor of Physical Therapy at Stanford.
