Charles Franklin Kettering (August 29, 1876 – November 25, 1958) sometimes known as Charles Fredrick Kettering[1] was an American inventor, engineer, businessman, and the holder of 186 patents.[2] He was a founder of Delco, and was head of research at General Motors from 1920 to 1947. Among his most widely used automotive developments were the electrical starting motor[3] and leaded gasoline.[4] In association with the DuPont Chemical Company, he was also responsible for the invention of Freon refrigerant for refrigeration and air conditioning systems. At DuPont he also was responsible for the development of Duco lacquers and enamels, the first practical colored paints for mass-produced automobiles. While working with the Dayton-Wright Company he developed the "Bug" aerial torpedo, considered the world's first aerial missile.[5] He led the advancement of practical, lightweight two-stroke diesel engines, revolutionizing the locomotive and heavy equipment industries. In 1927, he founded the Kettering Foundation, a non-partisan research foundation, and was featured on the cover of Time magazine in January 1933.
Charles was born in Loudonville, Ohio, United States, the fourth of five children of Jacob Henry Kettering and Martha (Hunter) Kettering. Poor eyesight gave him headaches in school. After graduation he followed his sister Emma into a teaching position at Bunker Hill School. By all accounts he was an engaging and innovative teacher. He attracted students to evening scientific demonstrations on electricity, heat, magnetism, and gravity.[6]
He took classes at the College of Wooster, before transferring to Ohio State University. He was a member of the Delta Upsilon fraternity. Eye problems forced him to withdraw, and he took a job as foreman of a telephone line crew. At first, the termination of his studies caused him to be depressed.[7] Then he found ways to apply his electrical engineering skills on the job, and his spirits revived. He also met his future wife, Olive Williams. When his eye condition improved, he was able to return to his studies and graduated from OSU in 1904 with an electrical engineering degree.[citation needed]
Kettering was hired directly out of school to head the research laboratory at National Cash Register (later known as NCR Corporation). Kettering invented an easy credit approval system, a precursor to today's credit cards, and the electric cash register in 1906, which made ringing up sales physically much easier for sales clerks. Kettering distinguished himself as a practical inventor. As he said, "I didn't hang around much with other inventors and the executive fellows. I lived with the sales gang. They had some real notion of what people wanted."[8] During his five years at NCR, from 1904 to 1909, Kettering secured 23 patents for NCR. He attributed his success to a good amount of luck but added, "I notice the harder I work, the luckier I get."[9]
Beginning in 1907, his NCR colleague Edward A. Deeds convinced Kettering to develop improvements for the automobile.[10] Deeds and Kettering invited other NCR engineers, including Harold E. Talbott, to join them nights and weekends in their tinkering at Deeds's barn. They became known as the "Barn Gang," and Kettering was called Boss Ket. Their first goal was to find a replacement for the magneto.[11]
The hand crank used to start early automobiles could kick back under some circumstances. Byron Carter, founder of Cartercar, died from complications after such an accident in Detroit's Belle Isle park. Henry M. Leland – the head of Cadillac – became determined to develop an electric self-starting device.[12]
When Leland's engineers failed to develop a self-starter small enough to be practical[13] he consulted Kettering, and Delco developed a practical model by February 1911.[14]
Kettering's key insight lay in devising an electrical system performing the three functions it still serves in modern cars: starter; producer of spark for ignition; and source of current for lighting.[15] Leland ordered 12,000 self-starters for his 1912 models; Delco had to then transition from its research and development activities to production.
The invention won a Dewar Trophy in 1913.[16]
In 1914, Flxible Sidecar Company was incorporated with the help of Kettering, who then became president of the company and joined the board of directors. Kettering provided significant funding for the company in its early years, particularly after 1916, when Kettering sold his firm, the Dayton Engineering Laboratories Company (Delco), to United Motors Company for 2ドル.5 million. Kettering continued to serve as president of Flxible until he became chairman of the board in 1940, a position that he held until his death in 1958.
Delco was sold to General Motors in 1918, as part of United Motors. Delco became the foundation for the General Motors Research Corporation and Delco Electronics. Kettering became vice-president of General Motors Research Corporation in 1920 and held the position for 27 years.[citation needed]
Between 1918 and 1923, he led the research and development at GM's Dayton research laboratories to commercialize air-cooled engines for cars and trucks.[18] The GM "copper-cooled" automotive engine used fans forcing air across copper fins for heat dissipation. The commercialization, attempted between 1921 and 1923, was unsuccessful due to a combination of factors, nontechnical and technical.[18] Air-cooled engines have had commercial success before and since, used widely in such applications as lawnmowers, small aircraft, and automobiles - notably the Volkswagen Beetle and many generations of Porsche sports cars.
Kettering's research in fuel was based on his belief that oil would be in short supply and additives would allow more efficient engines with higher compression.[19] His "high percentage" solution was to mix ethanol with gasoline, while his "low percentage solution" looked for additives that would be added in small quantities to increase what later would be called the octane rating of gasoline.[19]Thomas Midgley Jr. and Kettering identified tetraethyllead (TEL) in December 1921 as an additive that would eliminate engine knocking at a dilution of one thousand to one.[19] While use of ethanol could not be patented, TEL's use as an additive could. Kettering and Midgley secured its patent and proceeded to promote the use of TEL as an additive instead of other options.[20] Kettering became the first president of the newly founded Ethyl Corporation that started to produce TEL in 1923.[21] One year later, he hired Robert A. Kehoe as the medical expert to proclaim that leaded gasoline was safe for humans. That its use was an ecological disaster leading to a global lead contamination was not acknowledged until many decades later.[20]
Kettering married Olive Williams of Ashland, Ohio, on August 1, 1905.[22] Their only child, Eugene Williams Kettering, was born on April 20, 1908. Eugene joined Winton Engine in 1930, which was acquired by General Motors and was eventually incorporated into the General Motors Electro-Motive Division (EMD). He became a central figure in the development of the EMD 567 locomotive engine and the Detroit Diesel 6-71 engine, serving at EMD until his retirement in 1960.[23]
Charles Kettering built a house, "Ridgeleigh Terrace", in 1914. According to local sources, it was the first in the United States to have electric air conditioning using freon.[24] Ridgeleigh Terrace was the home of his son, Eugene, until his death. Eugene's wife, Virginia, lived in the house for many years, restoring and redecorating it. In the late 1990s, the house largely destroyed in a fire, and was rebuilt with serious deviation from the original blueprints to accommodate its current use as a conference center.
Some of Charles' memorable quotations are: "It doesn't matter if you try and try and try again, and fail. It does matter if you try and fail, and fail to try again.", "Failures are finger posts on the road to achievement.", "My interest is in the future because I am going to spend the rest of my life there." .[25]
Kettering died on November 25, 1958. After his death, his body lay in honor at the Engineers Club and then was interred in the mausoleum at Woodland Cemetery, Dayton, Ohio.[citation needed]
Max D. Liston, one of Kettering's co-workers at GM, described him "one of the gods of the automotive field, particularly from an inventive standpoint."[26]: 4 Liston quoted Kettering as advising him, "People won't ever remember how many failures you've had, but they will remember how well it worked the last time you tried it."[26]: 7
Kettering and Deeds had a lifelong business, professional and personal relationship. In 1914, recognizing that Dayton was among the leading industrial cities in the US because of the skilled engineers and technicians in the city, they founded the Engineers Club of Dayton and the Foreman's Club of Dayton, which later on became the National Management Association.
Kettering held 186 U.S. patents. He invented the all-electric starting, ignition, and lighting system for automobiles. Electric starters replaced crank (manual) starting of automobiles. First incorporated in the 1912 Cadillac, all-electric starting aided in the growth of the US auto industry by making the automobile easy for anyone to start. Other patents included a portable lighting system and an incubator for premature infants. His engine-driven generator was combined with storage batteries to form a "Delco Plant", providing electrical power for farmsteads and other locations far from the power grid.
In 1918 Kettering designed the "aerial torpedo", nicknamed the Kettering Bug.[5]
Kettering and colleagues' development of leaded gasoline ultimately caused the release of large quantities of lead into the atmosphere as a result of the combustion of leaded gasoline all over the world.[27] Due to the neurotoxic effects of lead, leaded gasoline has been widely banned since the late 1990s. The development of Freon[28] using CFCs has been implicated in the depletion of the ozone layer.
His inventions, especially the electric automobile starter, made him wealthy. In 1945, he helped found what became the Memorial Sloan Kettering Cancer Center, based on the premise that American industrial research techniques could be applied to cancer research.[citation needed]. His son and daughter-in-law, Eugene and Virginia, created Kettering Medical Center in Ohio, as a tribute to Charles Kettering's life and his work in healthcare research.
At Antioch College, the 1929 Science Building he donated[33] was not named after him (it is now the Arts and Science Building),[34] but the school's 33.000-square-foot Charles F. Kettering Building was (the same being originally a research facility, now home to campus radio station WYSO),[35] while the college's Olive Kettering Library was named after his wife.[36]
