Émile Hilaire Amagat (2 January 1841 – 15 February 1915) was a French physicist.[1] His doctoral thesis, published in 1872, expanded on the work of Thomas Andrews, and included plots of the isotherms of carbon dioxide at high pressures.[2] Amagat published a paper in 1877 that contradicted the current understanding at the time, concluding that the coefficient of compressibility of fluids decreased with increasing pressure.[2] He continued to publish data on isotherms for a number of different gases between 1879 and 1882,[2] and invented the hydraulic manometer, which was able to withstand up to 3200 atmospheres, as opposed to 400 atmospheres using a glass apparatus.[3] In 1880 he published his Law of Partial Volumes.
Amagat was elected a member of the French Academy of Sciences on 9 June 1902.[4] A unit of number density, amagat, was named after him.
The French Academy of Sciences gave him the posthumous award of the Prix Jean Reynaud for 1915.[5]
