Thermometer high coefficient of expansion) for the first time and the quality of his production could provide a finer scale and greater reproducibility, leading to its general adoption. In 1742, Anders Celsius (1701–1744) proposed a scale with zero at the boiling point and 100 degrees at the freezing point of water, though the scale which now bears his name has them the other way around. French entomologist René Antoine Ferchault de Réaumur invented an alcohol thermometer and temperature scale in 1730 that ultimately proved to be less reliable than Fahrenheit's mercury thermometer. The first physician that put thermometer measurements to clinical
Delisle scale of Linnaeus thermometers, Daniel Ekström. The Delisle thermometer remained in use for almost 100 years in Russia. One of its users was Mikhail Lomonosov, who reversed it, as Jean-Pierre Christin did with Celsius' scale, making the freezing point of water 0 °D and the boiling point 150 °D. Delisle scale The Delisle scale (°D) is a temperature scale invented in 1732 by the French astronomer Joseph-Nicolas Delisle (1688–1768). Delisle was the author of "Mémoires pour servir à l'histoire et aux progrès de l'Astronomie, de la Géographie et de la Physique" (1738). In 1732, Delisle built a thermometer that used mercury
