[Albrecht von Graefe and internationality].

Not only the scientific successes but also his personality caused Albrecht von Graefe (1828-1870) to gain a worldwide reputation. His two foundations "Archive for Ophthalmology" in 1854 and the "(German) Ophthalmological Society" (DOG) in 1857 as well as his famous eye clinic in Berlin were important for his colleagues and patients from many countries and most continents. The 2017 DOG congress has the motto "German Ophthalmology internationally"; thus, it is worthwhile to be reminded of this great ophthalmologist.
