Theodor Albrecht Edwin Klebs (6 February 1834 – 23 October 1913) was a German-Swiss microbiologist. He is mainly known for his work on infectious diseases. His works paved the way for the beginning of modern bacteriology, and inspired Louis Pasteur and Robert Koch. He was the first to identify a bacterium that causes diphtheria, which was called Klebs–Loeffler bacterium (now Corynebacterium diphtheriae). He was the father of physician Arnold Klebs.

Walther Kruse (September 8, 1864 – 1943) was a German bacteriologist who was a native of Berlin.
In 1888 he received his doctorate from Berlin, where he was a student of Rudolf Virchow (1821–1902). From 1889 until 1892 he worked as a bacteriologist in Naples, and in 1892 travelled to Egypt to perform research on dysentery. In 1893 he became an assistant to hygienist Carl Flügge (1847–1923) in Breslau, and in 1898 became an associate professor at the University of Bonn. Later he served as a full professor in Königsberg (1900), Bonn (1911) and Leipzig (1913).
Walther Kruse is remembered for his work in parasitology and his research of intestinal bacteria infections. He performed extensive studies of Shigella dysenteriae during an epidemic of dysentery in the Ruhr area of Germany. This organism is sometimes referred to as the "Shiga–Kruse bacillus", and its associated disease as "Shiga–Kruse dysentery". These eponyms are shared with Japanese bacteriologist Kiyoshi Shiga (1871–1957). Kruse documented his findings in a 1900 treatise titled Über die Ruhr als Volkskrankheit und ihren Erreger.
In 1914 he demonstrated that the common cold could be transmitted to healthy individuals via nasal secretions that were free of bacteria. The results of these experiments were published in a treatise called Die Erreger von Husten und Schnupfen (1914). A specialized tool used to spread material over the surface of a culture medium is called "Kruse's brush".

Christian Møller (22 December 1904 in Hundslev, Als – 14 January 1980 in Ordrup) was a Danish chemist and physicist who made fundamental contributions to the theory of relativity, theory of gravitation and quantum chemistry. He is known for Møller–Plesset perturbation theory and Møller scattering.
His suggestion in 1938 to Otto Frisch that the newly discovered process of nuclear fission might create surplus energy, led Frisch to conceive of the concept of the nuclear chain reaction, leading to the Frisch–Peierls memorandum, which kick-started the development of nuclear energy through the MAUD Committee and the Manhattan Project.Møller was the director of the European Organization for Nuclear Research (CERN)'s Theoretical Study Group between 1954 and 1957 and later a member of the same organization's Scientific Policy Committee (1959-1972).
