Alfred Pérot
Jean-Baptiste Alfred Perot (; 3 November 1863 – 28 November 1925) was a French physicist. Together with his colleague Charles Fabry he developed the Fabry–Pérot interferometer in 1899. The French Academy of Sciences awarded him the Janssen Medal for 1912. The Royal Society awarded Fabry and Perot the Rumford medal in 1918. Spelling There is some confusion about the spelling of Perot's last name. Perot himself used the spelling ''Pérot'' in scientific publications, but according to the French civil registry, his family name In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community.

Eugène Pirou
Louis Eugène Pirou (26 September 1841 – 30 September 1909) was a French photographer and filmmaker, known primarily for his portraits of celebrities and scenes from the Paris Commune. He was awarded a gold medal at the Exposition Universelle of 1889. Life and work He owned numerous studios in Paris, mostly on the Boulevard Saint-Germain, but he also operated one at an old evangelical mission on the Rue Royale. That one was sold to a photographer named Arthur Herbert, in 1889, with permission to use Pirou's name. In 1898, Herbert sold the studio to the brothers Georges and Oscar Mascré (1865-1943), who continued to use Pirou's name without his permission. Pirou lost a complicated lawsuit against the brothers, who compounded the fraud by referring to the studio as "Otto-Pirou", in reference to Otto Wegener, a Swedish-born photographer who was also not associated with them.Camille Blot-Wellens, "Eugène Pirou, portraitiste de la Belle Époque", in ''Revue de la Bibliothèqu ...

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ...

Family Name
In some cultures, a surname, family name, or last name is the portion of one's personal name that indicates one's family, tribe or community. Practices vary by culture. The family name may be placed at either the start of a person's full name, as the forename, or at the end; the number of surnames given to an individual also varies. As the surname indicates genetic inheritance, all members of a family unit may have identical surnames or there may be variations; for example, a woman might marry and have a child, but later remarry and have another child by a different father, and as such both children could have different surnames. It is common to see two or more words in a surname, such as in compound surnames. Compound surnames can be composed of separate names, such as in traditional Spanish culture, they can be hyphenated together, or may contain prefixes. Using names has been documented in even the oldest historical records. Examples of surnames are documented in the 11th c ...

Civil Registry
Civil registration is the system by which a government records the vital events (births, marriages, and deaths) of its citizens and residents. The resulting repository or database has different names in different countries and even in different US states. It can be called a civil registry, civil register (but this is also an official term for an individual file of a vital event), vital records, and other terms, and the office responsible for receiving the registrations can be called a bureau of vital statistics, registry of vital records and statistics, registrar, registry, register, registry office (officially register office), or population registry. The primary purpose of civil registration is to create a legal document (usually called a ''certificate'') that can be used to establish and protect the rights of individuals. A secondary purpose is to create a data source for the compilation of vital statistics. The United Nations General Assembly in 1979 adopted the Convent ...

Rumford Medal
The Rumford Medal is an award bestowed by Britain's Royal Society every alternating year for "an outstandingly important recent discovery in the field of thermal or optical properties of matter made by a scientist working in Europe". First awarded during 1800, it was created after a 1796 donation of $5000 by the scientist Benjamin Thompson, known as Count Rumford, and is accompanied by a gift of £1000. Since its inception, the award has been granted to 104 scientists, including Rumford himself during 1800. It has been awarded to citizens of the United Kingdom sixty-one times, France fourteen times, Germany eight times, the Netherlands seven times, Sweden four times, the United States three times, Italy twice and once each to citizens of Australia, Hungary, Belgium, Luxembourg and New Zealand.

Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by King Charles II as The Royal Society and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the Society's President, according to a set of statutes and standing orders. The members of Council and the President are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS (Fellow of the ...

Charles Fabry
Maurice Paul Auguste Charles Fabry (; 11 June 1867 – 11 December 1945) was a French physicist. Life Fabry graduated from the École Polytechnique in Paris and received his doctorate from the University of Paris in 1892, for his work on interference fringes, which established him as an authority in the field of optics and spectroscopy. In 1904, he was appointed Professor of Physics at the University of Marseille, where he spent 16 years. Career In optics, he discovered an explanation for the phenomenon of interference fringes. Together with his colleague Alfred Pérot he invented the Fabry–Pérot interferometer in 1899. He and Henri Buisson discovered the ozone layer in 1913. In 1921, Fabry was appointed Professor of General Physics at the Sorbonne and the first director of the new Institute of Optics. In 1926 he also became professor at the École Polytechnique. He was the first general director of the Institut d'optique théorique et appliquée and director of "gra ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of phenomena, and usually frame their understanding in mathematical terms. Physicists work across a wide range of research fields, spanning all length scales: from sub-atomic and particle physics, through biological physics, to cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their knowledge towards solving practical problems or to developing new technologies (also known as applie ...
