Abstract
Guillaume Amontons (1663-1705) was an experimentalist who devoted himself to the improvement of instruments employed in physical experiments, particularly the barometer, and the thermometer. Of special note are a folded barometer, a cisternless barometer to be used at sea, and a hygrometer of his invention. He experimented with an air-thermometer and pointed out that the extreme cold of such a thermometer would be that which reduced the spring of the air (pressure) to nothing, thus being the first to recognize that the use of air as a thermometric substance led to the inference of the existence of a zero of temperature. During his studies on the behavior of air he established that at constant volume the pressure varied inversely to the temperature. He devised an external-combustion machine and was among the first to study problems due to
