He studied medicine and natural sciences in Jena and in Wurzburg. According to a memoir written by Koch's wife, Therese Koch (T.

Koch had broad interests including zoology, geology and geography, anthropology, archeology and history but his main interest was with botany, especially horticulture, dendrology and the origin of fruit trees (Edmundson & Lack, 1977).
