Giovanni Sansone (24 May 1888 – 13 October 1979) was an Italian mathematician, known for his works on mathematical analysis, on the theory of orthogonal functions and on the theory of ordinary differential equations.He was an Invited Speaker of the ICM in Bologna in 1928.
Julius Ferdinand Ruska (9 February 1867, Bühl, Baden – 11 February 1949, Schramberg) was a German orientalist, historian of science and educator.
He was a critical scholar of alchemical literature, and of Islamic science, raising many issues on attributions and sources of the texts, and providing translations.

Max Robitzsch (2 February 1887 – 10 June 1952) was a German meteorological scientist and university professor. He invented the "Robitzsch Actinograph", a type of pyranometer and wrote numerous scientific books and articles.
He was born in Höxter, Province of Westphalia. He also undertook an expedition into the Scandinavian arctic to research atmospheric phenomena, spending the 1912/1913 winter in Spitsbergen, Norway. His mission, together with Kurt Wegener, brother of Alfred Wegener, was to set up a meteorological observatory for the German Geophysical Observatory, which they did at the Crossbai, Ebeltofthafen (Ebeltofthamna in Norwegian). During the long winter stay, they and two helpers performed 275 pilot balloon soundings, 98 tethered balloon soundings and 19 probe launches with the help of a hang glider. As of 2000, only some archeological remains of the obersvatory could be found.For much of his life (since at least 1917), he worked as a professor at the Meteorological Observatory Lindenberg (German Wikipedia) in Lindenberg, Brandenburg. During the Cold War, he there undertook numerous extensive radio sounding studies of the atmosphere with weather balloons, reputedly at the behalf of the Soviet occupation forces in East Germany.During January to May 1950, he was director of the Meteorologisches Observatorium Lindenberg, before later on becoming professor at (and possibly the director of) the Geophysical Institute of Leipzig, later subsumed in the University of Leipzig.
Franco Dino Rasetti (August 10, 1901 – December 5, 2001) was an Italian (later naturalized American) physicist, paleontologist and botanist. Together with Enrico Fermi, he discovered key processes leading to nuclear fission. Rasetti refused to work on the Manhattan Project on moral grounds.

John Paul Larkin (March 13, 1942 – December 3, 1999), known professionally as Scatman John, was an American musician.

He recorded five albums, which were released between 1986 and 2001.
In the United States and Europe, Larkin is recognized for his 1995 singles "Scatman (Ski-Ba-Bop-Ba-Dop-Bop)" and "Scatman's World". He achieved his greatest success in Japan, where his album Scatman's World (1995) sold over a million copies. Outside of his musical activities, he had deepened exchanges with stuttering organizations and established the Scatland Foundation in 1996 with the purpose of furthering research of and educating the public on stuttering. Larkin was a recipient of the American Speech–Language–Hearing Association's Annie Glenn Award for outstanding service to the stuttering community and a posthumous inductee to the National Stuttering Association Hall of Fame.
Harold Joe Waldrum (August 23, 1934 – December 13, 2003) was an American artist whose abstract works depict color studies especially of the old adobe churches of Northern New Mexico. He also used a Polaroid SX-70 camera to photograph many of the churches, initially as part of the process in creating his paintings. However, this collection of thousands of photographs became a body of work in and of itself and was exhibited at several galleries and museums.
Before pursuing an artistic career, Waldrum graduated from Western State College and became a public school teacher in Kansas, where he taught music and art for a decade-and-a-half. After receiving a graduate degree from Fort Hays State College in 1970, he became a full-time painter, moving to New Mexico, the focal point of much of his work.
In the later part of his career, Waldrum endeavored to preserve the historic churches that were the inspiration for his paintings. In 1985, he founded an organization to promote this goal and produced a series of documentaries about the deterioration and ultimately demolition of the churches. In the 1980s and 90s, he collaborated with a few printmakers to create a collection of aquatint etchings and linocuts in a style very similar to his paintings.
Waldrum died on December 13, 2003, and he is buried in Columbus, New Mexico, a village near the Mexico–United States border. His works are held in the collections of the Museum of New Mexico, the Palm Springs Art Museum, the Albuquerque Museum, and the Harwood Foundation of Taos, New Mexico.

In addition, from 1892 to 1903, he was director of studies at the École pratique des hautes études.In 1873 he described the bivalve genera Matheronia and Toucasia (family Requieniidae). With paleontologist Charles Schlumberger, he conducted important investigations on sexual dimorphism in Foraminifera.In 1891 he was appointed president of the Société géologique de France. He was elected to the mineralogical section of the French Académie des sciences on 5 May 1903.In 1895, botanist Hermann zu Solms-Laubach published Chalmasia, which is a genus of green algae in the family Polyphysaceae and name in Chalmas's honour.He died in retirement at Aix-les-Bains, Provence.
