Arthur Groenouw

Arthur Groenouw (27 March 1862 – 1945) was a German ophthalmologist born in Bosatz, a village near Ratibor. 
He studied medicine in Breslau, and was an assistant to physiologist Rudolf Heidenhain (1834–1897) and ophthalmologist Wilhelm Uhthoff (1853–1927). In 1892 he was habilitated for ophthalmology in Breslau, and in 1899 attained the title of professor.

At the time, he believed that the two types were variations of the same disease. Later on, his findings on corneal dystrophy were classified as two separate syndromes:
