Marc-Auguste Pictet was a scientific journalist and an experimental natural philosopher born in Geneva, Republic of Geneva. Pictet's main contribution to learning was his editing of the Bibliothèque britannique, devoted to the diffusion on the Continent of scientific knowledge produced in Great Britain, his own scientific research was leaning towards physical sciences calorimetry, but astronomy, geology and technology chronometry and the manufacture of fine earthenware. He was born on 23 July 1752, the son of Charles Pictet, a military officer serving in the mercenary troops of Netherlands, hjis wife, Marie Dunant. Marc-Auguste studied natural philosophy and law at the Geneva Academy and qualified as a lawyer in 1774. After one year in England, he became assistant to Jacques-André Mallet at the Geneva Observatory and took an interest in meteorology and map-making. In 1778, he made his first trip around the Mont-Blanc with his master Horace-Bénédict de Saussure. In 1786, he would succeed him as professor of natural philosophy at the Academy of Geneva.
By this time, he assisted Horace-Benedict de Saussure with an experiment which demonstrated that infra-red radiation exists, in a follow up experiment, named Pictet's experiment by Count Rumford, demonstrated that cold can be reflected by focussing the radiation from a flask of ice onto a thermometer using two concave mirrors. The result of his experiments on heat was published in 1790 as Essai sur le feu. At this time he had converted to Lavoisier's chemistry. In 1791, Pictet was one of the twelve founding members of the Geneva Society of Physics and Natural History. In 1796, he, his younger brother Charles, his friend Frédéric-Guillaume Maurice began editing a monthly periodical entitled Bibliothèque Britannique, which carried translations of significant scientific papers published in English by scholars such as Davy, Herschel, Playfair, Rumford or Wollaston, it therefore covered a wide range of scientific and technical topics, as well as extracts of British literature and articles on agriculture.
After 1815, this periodical included other European materials and took from on the name of Bibliothèque Universelle de Genève. Between 1790 and 1819, Pictet was the director of the Geneva Observatory; as such, he oversaw the installation of a meteorological station, before setting up another one on Great St. Bernard mountain in the Alps. In 1815, the year Geneva adhered to the Swiss Confederation, Henri-Albert Gosse and Jakob Samuel Wyttenbach were the main agents in the creation of the Swiss Society of Natural Sciences. Pictet was a Fellow of the Royal Society of London and an "associé libre" of the Académie des Sciences, his expertise and correspondence network extended throughout Western Europe and as far as the United States, Thomas Jefferson. It included hundreds of scholars, he was elected a Fellow of the Royal Society of Edinburgh in 1796. The Geneva Society of Physics and Natural History offers a yearly award in history of science called the Marc-Auguste Pictet Prize, it awards a yearly medal to "a scholar whose work is recognized as an authority in the history of science".
Winners are chosen by a panel of University of field experts. In 1766 he married Susanne Francoise Turrettini.

Benedict Pictet was a Genevan Reformed theologian. He was born at Geneva on 19 May 1655. After receiving a university education there, he made an extensive tour of Europe, he assumed pastoral duties at Geneva, in 1686 was appointed professor of theology. He died there on 10 January 1724, at the age of 68. In the area of systematic theology, Pictet published two major works: Theologia Christiana, he sought to revive the old orthodox theology, but was unable to prevent the Genevan Company of Pastors from adopting a new formula of subscription in 1706. Pictet was known as Christian poet, some of his hymns being included in French hymnals. Other works were Huit sermons sur Vexamen des religions and Dialogue entre un catholique et un protestant.

Adolphe Pictet was a Swiss linguist and ethnologist. Pictet, the cousin of the biologist Francois Jules Pictet, is well known for his research in the field of comparative linguistics, he played a crucial formative role in the development of Ferdinand de Saussure. But he was "a dedicated champion of German Romanticism and idealist philosophy":Like French and Russian Romantics since the beginning of the century, he made a journey to Germany, where he became acquainted with A. W. Schlegel, Hegel and Schelling.... In the spirit of earlier wars between “romantics” and “classics”, Pictet envisioned Romanticism, with its embrace of pluralism and freedom of invention, as standing in sharp opposition to Classicism, the embodiment of systemic compactness and uniformity. Pictet "represented the first, Romantic generation of historical linguists, for whom the history of language went hand in hand with the history of the material and spiritual being of the people who spoke it", he was born in Geneva on 11 September 1799 the son of Charles Pictet de Rochamont.

Pic-Pic was a Swiss automobile manufactured in Geneva from 1906 to 1924. They were produced by the Piccard-Pictet Company until 1920, by Gnome et Rhône from 1920 until the demise of the marque in 1924. At the beginning of the 20th century two brothers and Frederic Dufaux, set about building their own race car; the design called for a straight-8 12-liter engine with about 80 horsepower. To produce the automobile, the two brothers contacted the Piccard-Pictet Company, which had the capability to manufacture such a vehicle; the elderly Paul Piccard did not think of the new invention of the automobile. On the other hand, Lucien Pictet thought; this friction led to the founding of the Société d’Automobiles, Geneva in 1905. This was a marketing company that contracted with Piccard-Pictet Company to manufacture the automobiles. In fact, the cars were known as SAGs until 1910. Lucien Pictet was appointed managing director. Léon Dufour was appointed chief designer, added technical director to his job titles.
Pictet traveled to Barcelona in early 1905, while there met with fellow Swiss Marc Birkigt of Hispano-Suiza. Pictet was so enamored of the Hispano-Suizas that he negotiated a licence agreement in August 1905. At the second annual International Geneva Motor Show in 1906, Piccard-Pictet/S. A. G. Displayed a 20/24 horsepower licensed Hispano-Suiza. In 1907, a 6-cylinder 28/32 horsepower car was introduced. In 1910, a 14/16 horsepower 2.4 liter 4-cylinder car was added. During World War I, the Swiss Army ordered a large number of Pic-Pics, which were known for their robustness. Indeed, these cars were in use until the late 1930s; the two post-war models used either a 2.9 liter 4-cylinder or a 5.9 liter V8. Sales of the cars declined after the war due to competition from imported brands; this led Piccard-Pictet Company to file for bankruptcy in 1920. Henceforth, Gnome et Rhône produced Pic-Pic cars, the last one being presented at the 1924 International Geneva Motor Show. In 1916 Commandant Yves le Prieur, a naval officer, used a Pic-Pic to demonstrate the safety and effectiveness of the Le Prieur rocket.
The Pic-Pic's ability to travel up to 80 Mph simulated the speed of the aircraft of the time. The successful test led to the use of LePrieur's rockets on Nieuport fighter aircraft against German balloon aircraft. Pic-Pics competed in a number of motorsports in their short existence. Two Pic-Pics with 4.5 liter engines and front wheel brakes competed in the 1914 Grand Prix, but both cars were withdrawn. In hillclimbing events, Pic-Pics competed more successfully. Pic-Pic cars came in first place in Vosges in 1909, Bern in 1911, Jaunpass in 1912, 1913, 1914.

Raoul-Pierre Pictet was a Swiss physicist. He was the first person to liquefy nitrogen. Pictet was born in Geneva, he served as professor in the university of that city. He devoted himself to problems involving the production of low temperatures and the liquefaction and solidification of gases. On December 22, 1877, the Academy of Sciences in Paris received a telegram from Pictet in Geneva reading as follows: Oxygen liquefied to-day under 320 atmospheres and 140 degrees of cold by combined use of sulfurous and carbonic acid; this announcement was simultaneous with that of Cailletet who had liquefied oxygen by a different process. Pictet died in Paris in 1929. Pictet, Raoul. Mémoire sur la liquefaction de l'oxygène, la liquefaction et la solidification de l'hydrogène: et sur les théories des changement des corps. J. Sandoz.

Pictet is a lunar impact crater located just to the east of the larger and more prominent impact crater Tycho. The high-albedo rays and ejecta from Tycho lie across Pictet and spread far to the east and in other directions. Pictet is somewhat worn by past impacts; the smaller crater Pictet A intrudes into the southwest rim. The larger crater Pictet E is nearly joined to the north rim. To the east is Saussure, to the northeast is the larger, worn formation Orontius. Swiss physicist Marc-Auguste Pictet was the student and colleague and friend of Horace-Bénédict de Saussure. By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint, closest to Pictet
