Christian Friedrich Samuel Hahnemann (10 April 1755 – 2 July 1843) was a German physician, known for creating an alternative form of medicine called homeopathy.

Christian Friedrich Samuel Hahnemann was born in Meissen, Saxony near Dresden. His father, along with many other family members, was a painter and designer of porcelain, for which the town of Meissen is famous.

As a young man, Hahnemann became proficient in a number of languages, including English, French, Italian, Greek and Latin. He eventually made a living as a translator and teacher of languages, gaining further proficiency in "Arabic, Syriac, Chaldaic and Hebrew".

Hahnemann studied medicine for two years at Leipzig. Citing Leipzig's lack of clinical facilities, he moved to Vienna, where he studied for ten months. After one term of further study, he graduated MD at the University of Erlangen on 10 August 1779, qualifying with honors. His poverty may have forced him to choose Erlangen, as the school's fees were lower. Hahnemann's thesis was titled Conspectus adfectuum spasmodicorum aetiologicus et therapeuticus.
