After 1900, he worked as a private scholar in Weimar.His primary work dealt with anatomical and pathological investigations of the cornea, as well as studies involving amyloid degeneration of conjunctiva and research of retinal detachment. In the Baltic states, he was at the forefront in the fight against trachoma. At Weimar, he conducted research of color perception and color photography.

Rudolf Albert Martin Boehm (Böhm) (19 May 1844, in Nördlingen – 19 August 1926, in Bad Kohlgrub) was a German pharmacologist, known for his work in the field of experimental pharmacology.

He conducted extensive studies on the actions of digitalis, muscarine (a product of certain mushrooms), choline and curare. In 1895 he classified curare into three groups; "calabash curares" (usually taken from the family Loganiaceae, Strychnos species), "tubo curares" (derived from the family Menispermaceae) and "pot curares" (mixed Menispermaceae and Loganiaceae substances). He also performed significant research of carbohydrate metabolism.

Regeneration und Transplantation (1917)
Methoden zur Erforschung der Regeneration bei Tieren (Methods for the Study of Regeneration in Animals) (1920)
