Émile Hilaire Amagat (2 January 1841 in Saint-Satur – 15 February 1915) was a French physicist. 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. 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. He continued to publish data on isotherms for a number of different gases between 1879 and 1882, and invented the hydraulic manometer, which was able to withstand up to 3200 atmospheres, as opposed to 400 atmospheres using a glass apparatus. In 1880 he published his law of partial volumes, now known as Amagat's law.
For his studies, he developed many original piezometer devices. His originality went so far as to use the depth of a mine shaft being drilled to reach high pressures of 430 atmospheres in order to study the equations of state of certain gases. His expertise led him to collaborate with the physicist Peter Tait in the development of a piezometer suitable for measuring the compressibility of liquids.Amagat was elected a member of the French Academy of Sciences on 9 June 1902. A unit of number density, amagat, was named after him. He was elected a foreign member of the Royal Society of London in 1897.The French Academy of Sciences gave him the posthumous award of the Prix Jean Reynaud for 1915.

Elizabeth of the Trinity, OCD (French: Élisabeth de la Trinité), born Élisabeth Catez (18 July 1880 – 9 November 1906), was a French Discalced Carmelite, a mystic, and a spiritual writer. She was known for the depth of her spiritual growth as a Carmelite as well as bleak periods in which her religious calling was perceived to be unsure according to those around her; she however was acknowledged for her persistence in pursuing the will of God and in devoting herself to the charism of the Carmelites.Elizabeth was a gifted pianist and had strong feelings for the Carmelite charism. Of that experience as a professed religious she wrote in a letter: "I can't find words to express my happiness. Here there is no longer anything but God. He is All; He suffices and we live by Him alone" (Letter 91).Pope John Paul II celebrated her beatification in Paris on 25 November 1984; Pope Francis approved her canonization on 3 March 2016. The date was decided at a gathering of cardinals on 20 June 2016 and she was canonized as a saint on 16 October 2016.

Théophile Moreux (20 November 1867 – 13 July 1954) was a French astronomer and meteorologist.

Jean Marie Julien Balland (26 July 1934 in Bué, Cher, France – 1 March 1998 in Lyon) was a Catholic Cardinal and Archbishop of Lyon.
