Gustave-Adolphe Hirn (21 August 1815 – 14 January 1890) was a French physicist, astronomer, mathematician, and engineer who made important measurements of the mechanical equivalent of heat and contributions to the early development of thermodynamics. He further applied his science in the practical development of steam engines.

Ferdinand Philippe Edouard Carré (11 March 1824 – 11 January 1900) was a French engineer, born at Moislains (Somme) on 11 March 1824. Carré is best known as the inventor of refrigeration equipment used to produce ice. He died on 11 January 1900 at Pommeuse (Seine-et-Marne).

Louis François René Panhard (27 May 1841 – 16 July 1908) was a French engineer, merchant and a pioneer of the automobile industry in France.
Born in Paris, he studied engineering at the Collège Sainte-Barbe and then graduated from École Centrale Paris in 1864. He was then employed by Jean-Louis Périn in a firm that produced wood-working machines. It was there that Panhard met Émile Levassor. In 1878, he was named Chevalier of the Legion of Honour.
In 1889 after the death of Jean-Louis Perin, Panhard partnered with Levassor and Edouard Sarazin (and his widow Louise) to enlarge Avenue d'Ivry in the 13th arrondissement of Paris, develop the French engine manufacturing licenses for Gottlieb Daimler internal combustion engine and found the Panhard & Levassor car company. The company produced its first automobile in 1890.
In 1891, Panhard and Levassor designed and produced the first Daimler car engine, the twin V. Panhard also participated in and won many automobile races including the Paris-Rouen, 1894, the first major motor race in the world, Paris-Bordeaux-Paris in 1895 and the Tour de France Automobile of 1899. Panhard cars dominated racing everywhere until 1900.
In 1897, Levassor died as the result of a racing accident. Panhard then joined with his son, Hippolytus, to continue with developing and producing automobiles including, by 1900, a wide range of luxury cars.
In 1904, Panhard won a grand prize at the St. Louis Exposition.
Panhard was also a mayor of Thiais in the département Val-de-Marne. In Paris, a street in the 13th arrondissement is named after him.
René Panhard died in 1908 in La Bourboule and was buried in the Père Lachaise Cemetery in Paris.

Émile Étienne Guimet (2 June 1836 – 12 August 1918) was a French industrialist, traveler and connoisseur.
He was born at Lyon and succeeded his father Jean-Baptiste Guimet in the direction of his "artificial ultramarine" factory. He also founded the Musée Guimet, which was first located at Lyon in 1879 and was handed over to the state and transferred to Paris in 1885.In Lyon he also established a library and a school for Oriental languages. Guimet aimed at spreading knowledge of Oriental civilizations, and facilitating religious studies, through sacred images and religious objects.Devoted to travel, he was in 1876 commissioned by the minister of public instruction to study the religions of the Far East, and the museum contains many of the fruits of this expedition, including a fine collection of Japanese and Chinese porcelain and many objects relating not merely to the religions of the East but also to those of Ancient Egypt, Greece and Rome.In 1945 Georges Salles, director of the Museums of France, redistributed the collections of national museum. The great collections of Asian arts of the Louvre Museum were transferred to the Musee Guimet. As a result, the Guimet became one of the greatest museums of Asian art in the world. It provides the most comprehensive panorama of Asian arts under one umbrella.Mata Hari was his long-time mistress.
In 1880 he started publishing Annales du Musee Guimet, in which original articles appear on Oriental Religions.
He wrote Lettres sur l'Algerie (1877) and Promenades japonaises (1880), and also some musical compositions, including a grand opera, Tai-Tsoung (1894)The Émile Guimet Prize for Asian Literature was created in his honour in 2017.

Jean-Baptiste Guimet (20 July 1795 – 8 April 1871), French industrial chemist, and inventor of synthetic colors, was born at Voiron, Isère.
He studied at the École Polytechnique in Paris, and in 1817 entered the Administration des Poudres et Salpêtres. As natural lazurite was expensive and inaccessible, different options for its artificial production were explored in Europe. Jean Baptiste Guimet discovered a synthetic route in 1826. He finally prepared the synthetic lazurite, called ultramarine in 1828. It was also called as French ultramarine.
In 1828 he was awarded the prize offered by the Société d’encouragement pour l’industrie nationale for a process of making artificial ultramarine with all the properties of the substance prepared from expensive natural source lapis lazuli; and six years later he resigned his official position in order to devote himself to the commercial production of that material, a factory for which he established at Fleurieu-sur-Saône.His son Émile Étienne Guimet succeeded him in the direction of the factory.
