Gabriel Bertrand (born 17 May 1867 in Paris, died 20 June 1962 in Paris) was a French pharmacologist, biochemist and bacteriologist.
Bertrand introduced into biochemistry both the term “oxidase” and the concept of trace elements.
The laccase, a polyphenol oxidase and an enzyme oxidating urishiol and laccol obtained from the lacquer tree, was first studied by Gabriel Bertrand in 1894.Bertrand's rule refers to the fact that the dose–response curve for many micronutrients is non-monotonic, having an initial stage of increasing benefits with increased intake, followed by increasing costs as excesses become toxic. In 2005, Raubenheimer et al. fed excess carbohydrates to Spodoptera littoralis and extended Bertrand's rule to macronutrients.In 1894, with Césaire Phisalix, he developed an antivenom for use against snake bites.Bertrand was made a member of the Académie Nationale de Médecine in 1931. In 1932 he became foreign member of the Royal Netherlands Academy of Arts and Sciences.

Marius Ely Joseph Sestier (8 September 1861 – 8 November 1928) was a French cinematographer. Sestier was best known for his work in Australia, where he shot some of the country's first films.
Born in Sauzet, Drôme, Sestier was a pharmacist by profession. He was employed by early filmmakers the Lumière brothers (Auguste and Louis Lumière) to demonstrate their cinématographe abroad. In this capacity he travelled to India in June 1896, where he held a showcase of six short films made by the Lumière brothers at Watson's Hotel, Bombay on 7 July 1896; this was the first time moving pictures had been shown in India. Sestier also shot his own films while in Bombay, but the Lumière brothers rejected these for their catalogue as they were not satisfied with the quality as French customs had opened the package of undeveloped film.After Sestier completed his work in India he travelled to Sydney where he met with Australian photographer Henry Walter Barnett, who had darkroom facilities to develop films locally.In September 1896 Sestier, Barnett and Charles Westmacott opened Australia's first cinema, the Salon Lumière in Pitt Street, Sydney. Sestier and Barnett began making their own films, starting with a short film of passengers disembarking from the ship PS Brighton in Manly, which was the first film shot and screened in Australia. Sestier and Barnett made approximately 19 films together in Sydney and Melbourne, most notably a film of the 1896 Melbourne Cup horse race. The feature, which consisted of 10 one-minute films shown in chronological order (separate films were required due to limitations of cameras of the time), was premiered at the Princess Theatre, Melbourne on 19 November 1896, with Sestier giving an accompanying lecture. It was covered in the Australian press, including The Age and The Bulletin, and has been cited as Australia's first film production.After his business partnership with Barnett ended Sestier continued to tour Australia, demonstrating the cinématographe and showcasing films until May 1897. After returning to France he went on to become director of the Lumière Patents Company.

Charlotte Jacobs (13 February 1847, Sappemeer - 31 October 1916, The Hague), was a Dutch feminist and pharmacist. She was the first of her gender in the Netherlands with a degree in pharmacology and also active within the women's movement. She was the sister of Aletta Jacobs.Charlotte Jacobs became the second female university student in the Netherlands when she started her studies in Amsterdam in 1877 and the first female pharmacist in 1879. She was a pharmacist at the Utrecht hospital in 1882–84.
In 1887–1912, she managed her own pharmacy in Batavia in the Dutch East Indies, and was as such the first female pharmacist in the Dutch East Indies.In 1908, she founded the first women's movement "Vereeniging voor Vrouwenkiesrecht" in the Dutch East Indies. She primarily fought for education opportunities for women in the colony, and not only for the Dutch women. She returned to the Netherlands in 1912, where she was active within woman suffrage and the peace movement.

The company grossed 1.972 billion euros in revenue in 2012. It employs approximately 10,000 people, with 6,700 of those jobs based in France. The success of the company placed Fabre as France's 43rd richest man at the time of his death in 2013.Fabre died in his home in Lavaur, Tarn department, on 20 July 2013, at the age of 87. The French employers' organisation, Mouvement des Entreprises de France, called his death "a huge loss." Castres Olympique's stadium was renamed as Stade Pierre-Fabre in memory of Fabre in 2017.

He was a founding member of the Left Radical Movement (MRG) in 1972 and served as the leader of the MRG until 1978. In this capacity, he became known as the "third man" - the third signatory of the Common Programme of the Union of the Left with François Mitterrand (PS) and Georges Marchais (PCF). He was himself excluded from the party in 1979 when he accepted a special research mission on work offered to him by right-wing President Valéry Giscard d'Estaing. He founded the Federation of Radical Democracy, but the party never achieved significant success.
He died in 2006, shortly after the death of Jean-Jacques Servan-Schreiber, his rival within the Radical-Socialist Party. Servan-Schreiber has been the leader of the right wing of the Radical Party.

Josef, Baron von Mering (28 February 1849, in Cologne – 5 January 1908, at Halle an der Saale, Germany) was a German physician.
Working at the University of Strasbourg, Mering was the first person to discover (in conjunction with Oskar Minkowski) that one of the pancreatic functions is the production of insulin, a hormone which controls blood sugar levels.
Mering was curious about the pancreas, a comma shaped organ, situated between the stomach and the small intestine. In an effort to discover its function, he removed the organ from a dog. The dog was then noticed frequently urinating on the floor, although it was house trained. Mering realised that this was a symptom of diabetes and tested the urine, which was found to be high in sugar, confirming his suspicion.
Josef von Mering helped to discover barbiturates, a class of sedative drugs used for insomnia, epilepsy, anxiety, and anesthesia. In 1903, he published observations that barbital (then known as diethyl-barbituric acid) has sedative properties in humans. In 1904, he helped to launch barbital under the brand name Veronal. Veronal was the first commercially available barbiturate sedative in any country. Von Mering collaborated with the chemist Emil Fischer, who was also involved in the discovery of barbital.
