Patrick Blanc (born June 3, 1953, Paris) is a French botanist who works at the French National Centre for Scientific Research, where he specializes in plants from tropical forests. He is the modern innovator of the green wall, specifically,
he invented the modern vertical hydroponics garden, which distinguishes it from its predecessors (aka. the Green Wall, Botanical Brick invented by Professor Stanley Hart White at the University of Illinois Urbana-Champaign in 1938).
Patrick Blancs contemporary patents are responsible for modernizing and popularizing the garden type. Blanc describes his vertical garden as follows:

On a load-bearing wall or structure is placed a metal frame that supports a PVC plate 10 millimetres (0.39 in) thick, on which are stapled two layers of polyamide felt each 3 millimetres (0.12 in) thick. These layers mimic cliff-growing mosses and support the roots of many plants. A network of pipes controlled by valves provides a nutrient solution containing dissolved minerals needed for plant growth. The felt is soaked by capillary action with this nutrient solution, which flows down the wall by gravity. The roots of the plants take up the nutrients they need, and excess water is collected at the bottom of the wall by a gutter, before being re-injected into the network of pipes: the system works in a closed circuit. Plants are chosen for their ability to grow on this type of environment and depending on available light.
This system exemplifies Blanc's ideas as a scientist and also the 15th target of the Haute Qualité Environnementale ("High Quality Environment") project, although the latter gives particular stress to use of more local species, at least outdoors.
In 2009 he was awarded an Honorary Fellow of the Royal Institute of British Architects.

Jean-Gaspard-Félix Laché Ravaisson-Mollien (French: [ʁavɛsɔ̃ mɔljɛ̃]; 23 October 1813 – 18 May 1900) was a French philosopher, 'perhaps France's most influential philosopher in the second half of the nineteenth century'. He was originally and remains more commonly known as Félix Ravaisson.His 'seminal' 'key' work was De l’habitude (1838), translated in English as Of Habit. Ravaisson's philosophy is in the tradition of French Spiritualism, which was initiated by Pierre Maine de Biran (1766–1824) with the essay "The Influence of Habit on the Faculty of Thinking" (1802). However, Ravaisson developed his doctrine as what he called 'spiritualist realism' and 'spiritualist positivism', and – according to Ravaisson scholar Mark Sinclair – can be thought of as founding 'the school of contingency'. His most well known and influential successor was Henri Bergson, with whom the tradition can be seen to end during the 1930s; although the 'lineage' of this 'philosophy of life' can be seen to return in the late twentieth century with Gilles Deleuze. Ravaisson never worked in the French state university system, in his late 20s declining a position at the University of Rennes. In 1838 he was employed as the principle private secretary to the Minister of Public Instruction, going on to secure high-ranking positions such as Inspector General of Libraries, and then the Curator of Classical Antiquities at the Louvre. Later in his life he was appointed as the President of the Jury of the Aggregation of philosophy in France, 'a position of considerable influence'. Ravaisson, was not only a philosopher, classicist, archivist, and educational administrator, but also a painter exhibiting under the name Laché.

Ernesto Schiaparelli (Italian pronunciation: [erˈnɛsto skjapaˈrɛlli]; July 12, 1856 – February 14, 1928) was an Italian Egyptologist.

Wilhelm Dörpfeld (26 December 1853 – 25 April 1940) was a German architect and archaeologist, a pioneer of stratigraphic excavation and precise graphical documentation of archaeological projects. He is famous for his work on Bronze Age sites around the Mediterranean, such as Tiryns and Hisarlik (the site of the legendary city of Troy), where he continued Heinrich Schliemann's excavations. Like Schliemann, Dörpfeld was an advocate of the historical reality of places mentioned in the works of Homer. While the details of his claims regarding locations mentioned in Homer's writings are not considered accurate by later archaeologists, his fundamental idea that they correspond to real places is accepted. Thus, his work greatly contributed to not only scientific techniques and study of these historically significant sites but also a renewed public interest in the culture and the mythology of Ancient Greece.

Carl Ritter (August 7, 1779 – September 28, 1859) was a German geographer. Along with Alexander von Humboldt, he is considered one of the founders of modern geography. From 1825 until his death, he occupied the first chair in geography at the University of Berlin.

Hermann Flohn (19 February 1912 – 23 June 1997) was a climatologist. Flohn was professor at the University of Bonn and head of the department at the Institute of Meteorology of Bonn University. He produced about 360 publications. Flohn was member in numerous scientific societies such as the Bavarian Academy, the Academy of Sciences Leopoldina, the New York Academy of Sciences, and the Royal Academy of Belgium.

André Briend is a French pediatric nutritionist best known for his 1996 co-formulation of Plumpy'nut, a Ready-to-Use Therapeutic Food (RUTF), with Dr. Mark Manary. Starting in 1994, Briend, who at the time worked at Institut de recherche pour le développement, worked with Michel Lescanne to develop variants of renutrition products in solid form. At the time, the WHO-recommended diet for the treatment of severe malnutrition required clean water, a commodity only available in hospitals in most developing countries. These trial products were ultimately discarded for not meeting the requirements of good shelf-life, pleasant taste, or logistic simplicity. In 1996, inspired by a jar of chocolate spread which had a similar composition of proteins, energy, and lipids as the diet recommended by the WHO, Briend came up with the idea of replacing part of the dry skim milk in the existing recipe with peanut butter and eventually created Plumpy'nut. Briend also served as a medical officer for the Department of Child & Adolescent Health and Development at the World Health Organization.
