September 19, 1895, marked the birth of Wilhelm Rudolf Alfred Klose in Görlitz, a figure whose academic trajectory spanned the volatile landscapes of twentieth-century German science. Throughout his career, he navigated complex shifts in applied mathematics, theoretical astronomy, and the structural pressures imposed by state-mandated research during the Second World War and its aftermath.
Academic Foundations and Early Research
Klose began his formal academic training at the University of Breslau and the University of Göttingen starting in 1916. By 1917, he secured a position as an assistant at the Breslau observatory. His doctoral research, supervised by Alexander Wilkens, focused on the movement of the planet 189 Phthia, which he completed in 1921. Subsequent efforts at the University of Greifswald led to his habilitation in 1922 and the appointment as a privatdozent. He further expanded his credentials with a habilitation at the Humboldt University of Berlin in 1923.

In 1924, Klose accepted a role as an associate professor of mechanics and theoretical astronomy at the University of Latvia in Riga. He returned to the Humboldt University of Berlin in 1929 as an associate professor of astronomy. In 1933, he succeeded Hilda Geiringer as assistant to Theodor Vahlen at the Institute for Applied Mathematics. Despite criticisms regarding his suitability due to his astronomical specialization, he became a full professor and director of the institute in 1937, bolstered by the support of Ludwig Bieberbach and Theodor Vahlen.
Wartime Activities and Institutional Decline
During the Second World War, the institute ceased productive mathematical output. Klose served as laboratory manager at a test center for the Army Weapons Office, conducting rocket research at Gottow and the Kummersdorf firing range near Luckenwalde. While external peer reviews from figures such as Ludwig Prandtl and Friedrich Pfeiffer characterized his expertise in applied mathematics as lacking, Klose maintained his professional standing within the national socialist framework until 1945.
Post-War Conscription and Final Years
Following the war, Klose worked at a GEMA successor company in Köpenick. From 1946 to 1952, he was conscripted into service under Operation Ossawakim and relocated to Gorodomlija near Ostashkov in the Soviet Union, joining a cohort of 169 German scientists, including Helmut Gröttrup and Fritz Karl Preikschat. He returned to academic life in 1952 as a full professor at the University of Rostock, where he focused on establishing an aeronautical engineering faculty. He died in Potsdam on February 21, 1953.
