Paul Marie Oudin (1851–1923) was a French physician and medical researcher. He was born, and later died, in Épinal. He conducted research in the Victorian era medical field of high frequency electrotherapy, the application of radio frequency electric currents to the body, and collaborated with the founder of the field, pioneering physiologist and biophysicist Dr. Jacques Arsene d'Arsonval. In 1893 he modified d'Arsonval's electrotherapy equipment by the addition of a wire coil resonator to produce higher potentials, inventing the Oudin coil. This device, very similar to a Tesla coil, could produce very high voltages from several hundred thousand to a million volts. In use, the brush discharges from a pointed electrode attached to the high voltage terminal of the coil would be played over various parts of the body to treat a variety of medical conditions. The Oudin coil was used in electrotherapy and diathermy through the 1920s.

Carl Reinhold August Wunderlich (4 August 1815, Sulz am Neckar – 25 September 1877, Leipzig) was a German physician, pioneer psychiatrist, and medical professor. He is known for his measurement of mean normal human body temperature of 37 °C (98.6 °F), now known more accurately to be about 36.8 °C (98.2 °F).

Johann Friedrich Wilhelm Camerer (17 October 1842 – 25 March 1910) was a German physician born in Stuttgart. Camerer was a pioneer in the field of pediatric medicine.He studied medicine at the universities of Tübingen and Vienna. At Tübingen he was a student of physiologist Karl von Vierordt (1818–1884). From 1867 to 1876 he was a general practitioner in several communities throughout Württemberg, afterwards working as a physician in the town of Riedlingen (1876–1884). During the Austro-Prussian War (1866) and Franco-Prussian War (1870–71), he served as a military physician.
From 1884 onward, he was a physician based in Urach, where he was later appointed Oberamtsarzt (medical officer). In 1895 he received an honorary degree in natural sciences from the University of Tübingen.
Camerer is remembered for his studies of infant nutrition and psychophysics as well as research involving metabolism in children. In 1894 he published an influential work on childhood metabolism called "Der Stoffwechsel des Kindes", etc. His work in pediatrics included important research on the composition of breast milk.

Harold (Hal) Masursky (December 23, 1922* – August 24, 1990) was an American astrogeologist.After leaving Yale University without defending his dissertation, he started his career in the early 1950s as a field geologist in Wyoming and Colorado working for the United States Geological Survey (USGS). In the early 1960s, he moved to the Astrogeology division of the USGS and began working at NASA's Jet Propulsion Laboratory in Pasadena, California. In the mid-1960s, he moved to Flagstaff, Arizona as a founding planetary geologist at the newly constructed USGS Astrogeology Science Center. Throughout his professional career with the USGS, his work contributed to the mission of NASA in the areas of economic, structural, and planetary geology.
He was responsible for the investigation of planetary and lunar surfaces, especially in finding scientifically valuable landing places. This included for the Apollo program, where, in the 1960s, he played a major role in choosing landing sites and assisted in training astronauts in the basics of geology so they would know what to look for on the surface of the Moon. In the 1970s, he headed the team that mapped the surface of Mars and was once again involved in choosing landing sites, this time for the Mars Viking missions. In the 1980s, he worked with the Voyager program to explore the surfaces of Jupiter, Saturn, Uranus, and Neptune.
Masursky was a strong advocate for the exploration of Venus and he was a key member of Pioneer Venus Orbiter team. He worked on numerous other space missions and programs, including, for Moon exploration, Ranger, Surveyor, the Lunar Orbiter, and the mapping of Mars by Mariner 9, as well as contributing to the missions of the Galileo and Magellan spacecraft. He was often interviewed on television as his enthusiasm for the planetary discoveries of the space missions was both edifying and infectiousAn especially key role was his work as the president of the Working Group for Planetary System Nomenclature of the International Astronomical Union (IAU). He created a small stir in 1986, when he was required to reject a popular suggestion that new moons of Uranus, discovered earlier that year, be named for the seven astronauts lost in the Space Shuttle Challenger explosion - the IAU has strict guidelines that prohibit major bodies being named in honor of persons from a particular country.In 1985, Masursky was the recipient of the Distinguished Service Award, which is the highest honorary recognition an employee can receive within the Department of the Interior. Quoting from the award, the 1985 USGS Yearbook states: “Harold Masursky, Geologist, for his imaginative leadership in the field of astrogeology which has influenced almost every facet of lunar and planetary exploration since the beginning of the nation's space program.”The Masursky crater on Mars was chosen because it is effluvial, meaning "flow" (it looks like water ran through it), to honor his fervent belief that Mars once had flowing water on the surface. In 1981, the asteroid 2685 Masursky was discovered and named in his honor. The Masursky Award for Meritorius Service to Planetary Science, first awarded to Carl Sagan in 1991, and the Masursky Lecture, originating in 1992 and given during the annual Lunar and Planetary Science Conference (LPSC), are named for him as well.
*Note there is some confusion about the year of Harold Masursky's birth; in some places it is reported as 1922 and in some places is reported as 1923.

Nathan Zuntz (6 October 1847, in Bonn – 22 March 1920, in Berlin) was a German physiologist born in Bonn. He was a pioneer of modern altitude physiology and aviation medicine.

Reinhold Trautmann (16 January 1883 – 4 October 1951) was a German Slavist. He is best known for his translations of the works of Slavic literature, such as his 1931 translation of the Primary Chronicle into German. He also conducted research of Slavic languages spoken in Germany.

Paul Rostock (18 January 1892 – 17 June 1956) was a Nazi physician, official, and university professor. He was chief of the Office for Medical Science and Research (Amtschef der Dienststelle Medizinische Wissenschaft und Forschung) under Third Reich Commissioner and Nazi war criminal Karl Brandt and a full professor, medical doctorate, medical superintendent of the University of Berlin Surgical Clinic.
After the end of World War II, he was tried as a war criminal in the Doctors' Trial for his complicity in medical atrocities performed on concentration camp prisoners.
