Charles Franklin Kettering (August 29, 1876 – November 25, 1958) sometimes known asCharles Fredrick Kettering[1] was an American inventor, engineer, businessman, and the holder of 186 patents.[2] He was a founder ofDelco, and was head of research atGeneral Motors from 1920 to 1947. Among his most widely used automotive developments were theelectrical starting motor[3] andleaded gasoline.[4] In association with theDuPont Chemical Company, he was also responsible for the invention ofFreon refrigerant forrefrigeration andair conditioning systems. At DuPont he also was responsible for the development ofDuco lacquers and enamels, the first practical colored paints formass-produced automobiles. While working with theDayton-Wright Company he developed the "Bug" aerial torpedo, considered the world's first aerial missile.[5] He led the advancement of practical, lightweighttwo-stroke diesel engines, revolutionizing thelocomotive andheavy equipment industries. In 1927, he founded theKettering Foundation, a non-partisan research foundation, and was featured on the cover ofTime magazine in January 1933.

Early life

[edit]

Charles was born inLoudonville, 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 theCollege of Wooster, before transferring toOhio State University. He was a member of theDelta 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 anelectrical engineering degree.[citation needed]

Career

[edit]

NCR

[edit]

Kettering was hired directly out of school to head the research laboratory atNational 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]

The Barn Gang

[edit]

Beginning in 1907, his NCR colleagueEdward A. Deeds convinced Kettering to develop improvements for the automobile.[10] Deeds and Kettering invited other NCR engineers, includingHarold 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 themagneto.[11]

Delco

[edit]

In 1909, Kettering resigned from NCR to work full-time on automotive developments, and the group incorporated asDayton Engineering Laboratories Company, or Delco.[citation needed]

The self-starter

[edit]

The hand crank used to start early automobiles could kick back under some circumstances.Byron Carter, founder ofCartercar, died from complications after such an accident in Detroit's Belle Isle park.[citation needed][dubiousdiscuss]Henry M. Leland – the head ofCadillac – 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]

Automobile electrical system

[edit]

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 aDewar Trophy in 1913.[16]

Kettering helped found theEngineers Club of Dayton in 1914.[17]

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), toUnited Motors Company for $2.5 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.

General Motors

[edit]

Delco was sold toGeneral Motors in 1918, as part of United Motors. Delco became the foundation for the General Motors Research Corporation andDelco 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 commercializeair-cooled engines for cars and trucks.[18] TheGM "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 theVolkswagen Beetle and many generations ofPorsche sports cars.

Leaded gas

[edit]

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 mixethanol with gasoline, while his "low percentage solution" looked for additives that would be added in small quantities to increase what later would be called theoctane rating of gasoline.[19]Thomas Midgley Jr. and Kettering identifiedtetraethyllead (TEL) in December 1921 as an additive that would eliminateengine 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 foundedEthyl Corporation that started to produce TEL in 1923.[21] One year later, he hiredRobert 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 globallead contamination was not acknowledged until many decades later.[20]

Personal life

[edit]

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 joinedWinton Engine in 1930, which was acquired by General Motors and was eventually incorporated into theGeneral Motors Electro-Motive Division (EMD). He became a central figure in the development of theEMD 567 locomotive engine and theDetroit 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 atWoodland Cemetery, Dayton, Ohio.[citation needed]

Legacy

[edit]

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 theEngineers 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, andlighting system for automobiles. Electric starters replaced crank (manual) starting of automobiles. First incorporated in the 1912Cadillac, 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 anincubator for premature infants. His engine-drivengenerator was combined with storage batteries to form a "Delco Plant", providing electrical power for farmsteads and other locations far from thepower grid.

In 1918 Kettering designed the "aerial torpedo", nicknamed theKettering Bug.[5]

Kettering and colleagues' development ofleaded 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 theneurotoxic effects of lead, leaded gasoline has been widely banned since the late 1990s. The development ofFreon[28] using CFCs has been implicated in thedepletion of the ozone layer.

He developed the idea ofDuco paint and helped developdiesel engines and ways to harnesssolar energy. He was a pioneer in the application ofmagnetism to medicaldiagnostic techniques.

His inventions, especially the electric automobile starter, made him wealthy. In 1945, he helped found what became theMemorial 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.

On January 1, 1998, the formerGeneral Motors Institute changed its name toKettering University to honor Kettering as a founder.[29]

In 1998, GMI Engineering and Management Institute (formerly General Motors Institute), ofFlint, Michigan, changed its name toKettering University in honor of Kettering. His ideals, prowess, and belief inco-operative education continue there. Kettering is also remembered through theMemorial Sloan-Kettering Cancer Center, a cancer research and treatment center in New York City, and through theKettering Health Network, which includes several hospitals and medical center campuses as well asKettering College inKettering, Ohio.

The city ofKettering, Ohio, a suburb of Dayton, was named after him when it was incorporated in 1955.

The formerU.S. Army Air Service testing field,McCook Field, is now a Dayton park called Kettering Field.

Several U.S. public schools are named after him:

The endowed Olive Williams Kettering Chair ofThe College of Wooster Department of Music is named in honor of his wife.

TheUniversity of Dayton's engineering building, Kettering Labs, is named after him.

The Kettering Science center on theAshland University campus in Ohio is named for him.

Kettering Hall atWilmington College is named for him, alsoKettering Hall of Science atOberlin College.[32]

AtAntioch 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 stationWYSO),[35] while the college'sOlive Kettering Library was named after his wife.[36]
