Arthur Groenouw 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.
In 1890 Groenouw described two different types of corneal dystrophy
, of which he published in an article named Knötchenförmige Hornhauttrübungen (noduli corneae). At the time he believed that they were variations of the same disease. Subsequently, his findings on corneal dystrophy were classified as two separate syndromes:
