In 1889 he was awarded a degree to teach math and sciences at [[Gymnasium (Germany)|gymnasiums]] (high schools). Later he earned a [[PhD]] in mathematics from the [[Martin Luther University of Halle-Wittenberg|University of Halle]] for a thesis on [[elliptic integral]]s (''Zur Darstellung des elliptischen Integrales erster Gattung''), his advisor was [[Lazarus Fuchs]].Menso Folkerts: [https://www.math.berlin/mathematiker/johannes-tropfke.html ''Johannes Tropfke (1866-1939)''] at the websites of the ''Berliner Mathematische Gesellschaft'' (Berlin mathematical society), retrieved 2019-01-25 (German)[http://www.genealogy.ams.org/id.php?id=53025 ''Johannes Tropfke''] at the [[Mathematics Genealogy Project]] (retrieved 2019-01-25)
