Hans Cornelius

Johannes Wilhelm Cornelius (27 September 1863 - 23 August 1947) was a German neo-Kantian philosopher and psychologist.

Born in Munich, Kingdom of Bavaria on 27 September 1863, he originally studied mathematics, physics, and chemistry, graduating with a Ph.D. in 1886, before turning to philosophy.

In 1910, Cornelius moved as a full professor to the Akademie für Sozialwissenschaften, which four years later would become a department of the newly founded University of Frankfurt.

[2] Cornelius, who was a consistent opponent of World War I, joined the Social Democratic Party of Germany (SPD) in 1918 and in the 1920s, he promoted the plan of a European confederation.

Hans Cornelius married Emilie (Mia) von Dessauer (1862–1946), a daughter of Heinrich von Dessauer (1830–1879), a physician and founder of the German hospital in Valparaiso, in 1887; Ingeborg Karlson (1894–1924), from Liljeholmen near Stockholm, in 1915, in his second marriage; and Friedrike Rosenthal, widowed Reissner (1886–1939), in 1925, in his third marriage.
