William Hoskins, with daughter Florence and wife Ada, ca. 1885-1890

William Hoskins (born 1862, Covington, Kentucky; died 1934, La Grange, Illinois)[1][2][3] was an American inventor, chemist, electrical engineer and entrepreneur in the late nineteenth and early twentieth 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 space heaters and toasters, and the invention of the first electric toaster.[citation needed]

Early life[edit]

  • Parents John and Mary Ann Hoskins[3]
  • completed 2 of 3 years of high school[1]
  • Conflicting source: Graduated class of 1879, Chicago High School[3]
  • no formal education in chemistry[1] but received "private instruction" in the field[3]
  • at age thirteen, joined the Illinois State Microscopical Society; at seventeen, the Society elected him secretary[2]

Work History:

  • 1880 (age seventeen) prepared chemical analysis samples[1] for Chicago-based consulting and analytical chemist Prof. Guy A. Mariner in the latter's commercial laboratory,[2] starting February 1880[3]
  • As of 1880, Mariner was one of the few completely commercial chemists in Chicago. (only 3)[1]
  • became Mariner's partner - firm renamed Mariner and Hoskins[1][2] (1885)[3]
  • After becoming a partner, Hoskins married Mariner's daughter,[1] Ada Mae[2]/May[3], December 18, 1883[3]
  • 1890 became sole proprietor[2][3]
  • Chilren: Minna, Edward, William, Florence[3]

Later...[edit]

  • became a partner in William A. Spinks & Co.[2][3] (1897)[2]
  • (1911 or earlier):
  • Hoskins was a charter member of the Chicago section of American Chemical Society (ACS)[1][6]). He served as chairman in 1897,[6] and also served as the national ACS's vice-president (1911 or earlier)[3]
  • 1917 became president of Hoskins Process Development Co.[2]

Hoskins became a recognized scientific expert witness in lawsuits[1], took out 37 US patents[1], and in his lab, Albert L. Marsh developed nichrome (Hoskins played a direct part).[1] Hoskins' 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]

Not surprisingly for a businessman, he was a Republican.[3]

Lived in La Grange.[3]

Billiard chalk[edit]

In the late 1800s, actual chalk (generally calcium carbonate, also known as calcite or carbonate of lime) was often used in cue sports on the leather tips of cue sticks to better grip the cue ball, but players experimented with other powdery, abrasive substances, since chalk itself was too abrasive, and over time damaged the game equipment.[7][8] In 1892,[8] The aforementioned straight rail billiards pro, William Spinks, was particularly impressed by a piece of natural chalk-like substance obtained in France, and presented it to Hoskins for analysis. Hoskins, having incidentally encountered such material before was able to quickly determine that it was volcanic ash (pumice) originally probably from Mount Etna, Sicily. Together, the two of them experimented with different formulations to achieve the cue ball "action" that Spinks sought.[4]

They settled on a mixture of Illinois-sourced[4] silica with small amounts of the abasive substance corundum or aloxite[5] (aluminum oxide, AL2O3),[9][10] founding the William A. Spinks Company in Chicago[4] after securing a patent on 9 March 1897[5]. Spinks later left the company, but it retained his name and was subsequently run by Hoskins, and later by Hoskins's cousin[4] Edmund F. Hoskin,[11] after Hoskins moved on to other projects.

The William A. Spinks Company product (which is still emulated by modern manufacturers today with slightly different, proprietary silicate compounds) effectively revolutionized billiards,[7][8] by providing a cue tip friction enhancer that allowed the tip to grip the cue ball briefly[5] and impart a previously unattainable amount of "english" (spin),[8] which consequently allowed more precise and more extreme cue ball control, made miscuing less likely, made curve and massé shots plausible, and ultimately spawned the new cue sport of artistic billiards. Even the basic draw and follow shots of pocket billiards (pool) depend heavily on the effects and properties of modern billiard "chalk".
