In early 1811Bradford, p. 76\. Hahnemann moved his family back to [Leipzig](/wiki/Leipzig "Leipzig") with the intention of teaching his new medical system at the [University of Leipzig](/wiki/University_of_Leipzig "University of Leipzig"). As required by the university statutes, to become a faculty member he was required to submit and defend a thesis on a medical topic of his choice. On 26 June 1812, Hahnemann presented a [Latin](/wiki/Latin "Latin") thesis, entitled *"A Medical Historical Dissertation on the Helleborism of the Ancients."*Bradford, p. 93\. His thesis very thoroughly examined the historical literature and sought to differentiate between the ancient use of *[Helleborus niger](/wiki/Helleborus_niger "Helleborus niger")*, or black hellebore, and the medicinal uses of the "white hellebore", botanically *[Veratrum album](/wiki/Veratrum_album "Veratrum album")*, both of which are poisonous plants.Haehl, Vol. 2, p. 96\.

Hahnemann continued practicing and researching homeopathy, as well as writing and lecturing for the rest of his life. He died in 1843 in Paris, at 88 years of age, and is entombed in a mausoleum at Paris's [Père Lachaise Cemetery](/wiki/P%C3%A8re_Lachaise_Cemetery "Père Lachaise Cemetery").
