[Gens Rulandica-Hungarian connections of a famous German family of physicians].

The Ruland family of German origin played an important role both in Hungarian and European medical history. Being a rather numerous family, and moreover, due to their habit of preferring to give the same first names to their children and because they worked in a relatively short period (ca. between 1550 and 1650), researchers often confuse one Ruland with the other.
