Guillaume Amontons

Born 31 Aug 1663; died 11 Oct 1705 at age 42.French physicist who developed the air thermometer - which relies on increase in volume of a gas (rather than a liquid) with temperature - and used it (1702) to measure change in temperature in terms of a proportional change in pressure. This observation led to the concept of absolute zero in the19th century. Deaf since childhood, Amontons worked on inventions for the deaf, such as the first telegraph, which relied on a telescope, light, and several stations to transmit information over large distances. Amontons' laws of friction, relied upon by engineers for 300 years, state that the frictional force on a body sliding over a surface is proportional to the load that presses them together and is also independent of the areas of the surfaces.
