Johan Hermann Wilhelm Rupe (October 9, 1866 in Basel – January 12, 1951) was a professor of organic chemistry at the University of Basel. His main field of interest was terpenes and campher as well as optical activity.
Rupe was born on October 9th, 1866 in Basel to Johannes Rupe and Mathilde Rupe (born Fischer) and went to school in Basel. He passed his "Maturität" in 1885 and then went on to study in Basel under Julius Piccard. He continued his studies at the University of Strasbourg under Rudolf Fittig and then in 1887 in Munich under Adolf von Baeyer. Rupe received his PhD in 1889 in Munich for his dissertation "Über die Reduktionsprodukte der Dichloromuconsäure".
In 1894 he went to Mulhouse to become head of the "Chemieschule" in the organic division. Rupe habilitated in 1895 in Basel, where he moved in 1899. In 1903, he became extraordinary professor for organic chemistry at the University of Basel. In 1911 or 1912 , he was promoted to ordinary professor for organic chemistry (while his colleague Friedrich Fichter became professor for inorganic chemistry). During his time as a professor, he supervised nearly 150 students and published over 250 scientific articles.
In 1907, he married Margrit Hagenback, daughter of Eduard Hagenbach-Bischoff with whom he had three children. His wife died in 1926 and in 1933 his youngest son died. In 1936 he married Marguerite Lutz.
Rupe retired in 1937 and died on January 12th, 1951.
