Reinhard Haupenthal
Reinhard Haupenthal was a German Esperantist, Volapükist, translator, and linguist. Donald J. Harlow described Haupenthal's personal style in a warning to potential readers of Haupenthal's translation of Goethe's Young Werther: "the vocabulary used by Haupenthal is far from standard, and at times the Esperanto verges on the incomprehensible."
