Wilbur Scoville Wilbur Scoville Wilbur Lincoln Scoville (January 22, 1865 – March 10, 1942) was an American pharmacist best known for his creation of the "Scoville Organoleptic Test", now standardized as the Scoville scale. He devised the test and scale in 1912 while working at the Parke-Davis pharmaceutical company to measure pungency, "spiciness" or "heat", of various chili peppers. Scoville was born in Bridgeport, Connecticut. He married Cora B. Upham on September 1, 1891 in Wollaston (Quincy, Massachusetts). They had two children: Amy Augusta, born August 21, 1892 and Ruth Upham, born October 21, 1897. Scoville wrote "The Art of Compounding", which
Scale of temperature Scale of temperature Scale of temperature is a way to measure temperature quantitatively. Empirical scales measure the quantity of heat in a system in relation to a fixed parameter, a thermometer. They are not absolute measures, that is why scales vary. Absolute temperature is thermodynamic temperature because it is directly related to thermodynamics. It is the Zeroth Law of Thermodynamics that leads to a formal definition of thermodynamic temperature. According to the zeroth law of thermodynamics, being in thermal equilibrium is an equivalence relation. Thus all thermal systems may be divided into a quotient set by this equivalence relation, denoted
