Kohler Disease

 Köhler was among the first physicians to apply X-rays to orthopedic diagnosis. 

In 1908, he published findings on osteochondrosis of the tarsal navicular bone in children, later named Köhler disease.

Köhler disease was first described in 1908 by German radiologist Alban Köhler (1874-1947) in his MWW article 

Uber eine häufige, bisher anscheinend unbekannte Erkrankung einzelner kindlicher Knochen [About a common, so far apparently unknown disease of individual children’s bones]
