Harald Ernst Malmsten Schering (November 25, 1880 – April 10, 1959) was a German physicist born in Göttingen. He is best known for his work in high voltage electricity and the Schering Bridge used in electrical engineering. Schering was the son of Ernst Schering, mathematician at the Göttingen Observatory. His mother came from a family of Swedish academics who worked with Ernst to translate works from French and Italian. Harald grew up with his two siblings in Göttingen and studied physics at the University of Göttingen. In 1903 he worked at the Geophysical Institute and obtained a Ph.D. in 1904 under Eduard Riecke with work on the Elster-Geitel dispersal apparatus. Beginning in 1905 he was a scientific assistant at the Physics and Technology Institute in Berlin Charlottenburg; today known as the Physikalisch-Technische Bundesanstalt (PTB). His work at the PTB under Emil Warburg primarily dealt with high voltage/high current research and development, and in 1914 he developed a measurement methodology for examining current transformers. In 1914 he was drafted into the First World War and was injured in 1916. In 1918 he became head of the high-voltage lab, succeeding Karl Willy Wagner. In 1919 he attained the title of professor at PTB with an annual salary of 4500 Marks and 1500 Marks as housing allowance. In 1924 he wrote a book on insulators in high voltage. A new institute was established in Hannover, buts construction was delayed by the war. Beginning in 1927, Schering was a professor of electrical engineering and high voltage technology at the Technical University of Hannover (today known as the Leibniz University Hannover). In 1933, he signed the Vow of allegiance of the Professors of the German Universities and High-Schools to Adolf Hitler and the National Socialistic State. He retired in 1949 but continued to work at the PTB until 1954 when Gerhard Pfestdorf took up a position to head the institution.Schering is remembered for invention of the Schering Bridge, which he developed along with Ernst Alberti is an AC bridge circuit used to measure capacitance and the dissipation factor of capacitors. Schering received a Golden Doctorate from the University of Göttingen in 1954 and an honorary doctorate from Braunschweig. He was awarded the Great Cross of Merit by the Federal Republic of Germany in 1957.

Evry Léon Schatzman (16 September 1920 – 25 April 2010) was a French scientist hailed as "the father of modern French astrophysics".

Antonio Rostagni (14 July 1903 – 5 December 1988) was an Italian physicist and academician.
He was a physicist involved in research in the fields of terrestrial physics, electromagnetic waves, and cosmic rays.
He was professor of physics at the University of Messina beginning in 1935 and at the University of Padua beginning in 1938. Among his students was Giuseppe Grioli.
Starting in 1950, he was a corresponding member of the Accademia dei Lincei of which he became a national member. He became a member of the Academy of Sciences of Turin in 1951.
Rostagni was vice-President of the Italian National Institute of Nuclear Physics from 1956 to 1958 and from 1958 to 1959 was director of the Research Division at the International Atomic Energy Agency (IAEA) at Vienna.

Vasco Ronchi (Italian: [ˈvasko ˈroŋki]; December 19, 1897 – October 31, 1988) was an Italian physicist known for his work in optics. He was born on 19 December 1897 in Florence, Italy. Along with Enrico Fermi, he was a student of Luigi Puccianti. He studied at the Faculty of Physics of the University of Pisa from 1915 to 1919.
In 1922 Ronchi published work describing testing methods for optics using simple equipment. The Ronchi test is widely used in amateur telescope making. The Ronchi ruling also bears his name.
He served numerous terms as the President of the 'Union Internationale d'Histoire des Sciences' within the UNESCO.
Ronchi authored 900 papers and 30 books.

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.

Eligio Perucca (28 March 1890 in Potenza – 5 January 1965 in Rome) was an Italian physics instructor and researcher at the University of Turin in Italy in the early decades of the twentieth century. He later served a professorship at the nearby Polytechnic University of Turin. He discovered an important principle in stereochemistry in 1919, but his contribution was overlooked and forgotten until recently.

Désiré Charles Emanuel van Monckhoven (1834–1882) was a Belgian chemist, physicist, and photographic researcher. He was also an inventor and author.
