Roland Paskoff (20 March 1933 – 14 September 2005) was a French geologist expert in coastal geomorphology including Holocene tectonics and sea level change. While he was active studying the coast of the countries where he held university positions—that is Chile, France and Tunisia— he also conducted studies in Bahrain, Malta, the Seychelles and the Mascarene Islands.

Venceslas Victor Jacquemont (8 August 1801 – 7 December 1832) was a French botanist and geologist known for his travels in India.
Born in Paris on August 8, 1801, Victor Jacquemont was the youngest of four sons of Frédéric François Venceslas Jacquemont de Moreau (1757-1836) and Rose Laisné. He studied medicine and later took an interest in botany. His early travels took him around Europe. He was lightly built and capable of living on a very frugal diet.
After being invited by the Jardin des Plantes to collect plant and animal specimens from a country of his choice for 240 pounds a year, Jacquemont traveled to India leaving Brest in August 1828. He arrived at Calcutta on 5 May 1829. He went to Delhi on 5 March 1830 and went onwards towards the western Himalayas. He visited Amber in Rajputana, met with the Sikh Emperor Ranjit Singh at his capital of Lahore, and visited the kingdom of Ladakh in the Himalaya. He also visited Bardhaman (Burdwan) in Bengal in November 1829. He died of cholera in Bombay on 7 December 1832. The standard author abbreviation Jacquem. is used to indicate this person as the author when citing a botanical name.Several plants are named for him, including Vachellia jacquemontii, the Himalayan White Birch (Betula jacquemontii), the Indian Tree Hazel (Corylus jacquemontii), Afghan Cherry (Prunus jacquemontii), and the cobra lily or Jack in the pulpit (Arisaema jacquemontii).

Pierre-Roland Giot (September 23, 1919 – January 4, 2002) was a French anthropologist, archaeologist and geologist.

David Harker (October 19, 1906 – February 27, 1991) was an American medical researcher who according to The New York Times was "a pioneer in the use of X-rays to decipher the structure of critical substances in the life process of cells".He is also well known for Harker–Kasper inequalities (statistical relationships between the phases of structure factors), which he devised in collaboration with John S. Kasper.
Harker made seminal discoveries in the field of chemical crystallography.His lab solved the structure of the pancreatic enzyme ribonuclease A, the third protein structure ever solved by protein crystallography.
Harker was a member of the National Academy of Sciences,
director of the protein structure program at the Polytechnic Institute of Brooklyn, director of the Center for Crystallographic Research at Roswell Park Comprehensive Cancer Center, and the head of the crystallography division of General Electric. After retirement from Roswell Park in 1976, he joined the Hauptman-Woodward Medical Research Institute (HWI), then known as the Medical Foundation of Buffalo. He remained there until his death in 1991. His research interests while at HWI turned towards mathematical aspects of crystallography, including color space groups and infinite polyhedra.Harker was awarded the Gregori Aminoff Prize from the Swedish Academy in 1984.

Leon Knopoff (July 1, 1925 – January 20, 2011) was an American geophysicist and musicologist. He received his education at Caltech, graduating in 1949 with a PhD in physics, and came to UCLA the following year. He served on the UCLA faculty for 60 years. His research interests spanned a wide variety of fields and included the physics and statistics of earthquakes, earthquake prediction, the interior structure of the Earth, plate tectonics, pattern recognition, non-linear earthquake dynamics and several other areas of solid Earth geophysics. He also made contributions to the fields of musical perception and archaeology.

Charles Friedel (French: [fʁidɛl]; 12 March 1832 – 20 April 1899) was a French chemist and mineralogist.

Catherine Joséphine "Katia" Krafft (née Conrad; 17 April 1942 – 3 June 1991) and her husband, Maurice Paul Krafft (25 March 1946 – 3 June 1991) were French volcanologists and filmmakers who died in a pyroclastic flow on Mount Unzen, Nagasaki, Japan, on 3 June 1991. The Kraffts became well known as pioneers in the filming, photographing, and recording of volcanoes, often coming within feet of lava flows. Their obituary appeared in the Bulletin of Volcanology. Since their deaths, their work has been featured in two documentary films by Werner Herzog, Into the Inferno (2016) and The Fire Within: A Requiem for Katia and Maurice Krafft (2022), and a further film, Fire of Love (2022), depicted their lives, relationship and careers using their archived footage.

Antoine François Alfred Lacroix (4 February 1863 – 12 March 1948) was a French mineralogist and geologist. He was born in Mâcon, Saône-et-Loire.

Paul Vidal de La Blache (French pronunciation: [pɔl vidal də la blaʃ], Pézenas, Hérault, 22 January 1845 – Tamaris-sur-Mer, Provence-Alpes-Côte d'Azur, 5 April 1918) was a French geographer. He is considered to be the founder of modern French geography and also the founder of the French School of Geopolitics. He conceived the idea of genre de vie, which is the belief that the lifestyle of a particular region reflects the economic, social, ideological and psychological identities imprinted on the landscape.
