William Hoskins (1862–1934)[1][2][3] was an American inventor, chemist, electrical engineer, and entrepreneur in the late 19th and early 20th centuries, most active in Chicago, Illinois. He became the co-inventor in 1897 of modern billiard chalk with professional carom billiards player William A. Spinks.[4][5] He is, however, best known for the invention of the electric heating coil – the basis for numerous ubiquitous household and industrial appliances, including electric stoves, space heaters, and toasters – and the invention of the first electric toaster.[6][7]

Career

Early life

William Hoskins was born in 1862 to parents John and Mary Ann Hoskins, in Chicago.[3] Hoskins would complete just two of three years of Chicago High School;[1][3] despite having an interest in chemistry, he would gain no formal education in chemistry throughout his early years.[1] Hoskins, however, received "private instruction" in the field,[3] before joining (at age thirteen), the Illinois State Microscopical Society. Four years later, at 17, the society elected him secretary.[2]

After leaving high school in 1880 at age 17, Hoskins prepared chemical analysis samples[1] for Chicago-based consulting and analytical chemist Guy A. Mariner in the latter's commercial laboratory,[2] starting in February.[3] Beginning in 1880, Mariner was one of only three completely commercial chemists in Chicago.[1] Five years after joining the laboratory, Hoskins became Mariner's partner; the firm was renamed Mariner and Hoskins.[1][2][3] Shortly before becoming the partner, Hoskins married Mariner's daughter,[1] Ada Mae,[a] in December 18, 1883.[3] In 1890, Hoskins became sole proprietor of the laboratory.[2][3] The couple subsequently had four children: Minna, Edward, William and Florence.[3]

Later career

In 1897, Hoskins began working with William A. Spinks before becoming a partner in William A. Spinks & Co.[2][3] In the early 1900s, Hoskins would also become the director of Hoskins Manufacturing Co., based in Detroit, creating electric heating appliances and pyrometers.[2][3] He was made a fellow of the American Association for the Advancement of Science (AAAS),[3] and was also a charter member of the Chicago section of the American Chemical Society (ACS),[1][8] of which he was the chairman in 1897,[8] later becoming the national ACS's vice-president,[3]. Hoskins Manufacturing eventually become Hoskins Process Development Co., of which he was the president.[2] Hoskins became a recognized scientific expert witness in lawsuits,[1] took out 37 US patents,[1] and in Hoskins's lab, Albert L. Marsh developed nichrome under supervision of Hoskins.[1][9] Hoskins's own innovations include a superior billiard chalk, materials used to construct race tracks (including the Washington Park Race Tracks in Chicago), safety paper for bank checks, a method for destroying weeds, and a gasoline blowtorch.[2][10]
