He began his medical studies at the Medical-Surgical College – Collegium medico-chirurgicum – in Berlin (1753-1754) and in 1755 enrolled at the University of Halle, where he graduated M.D. in 1759 and obtained his doctorate on November 28 that year with the famous dissertation Theoria generationis, In this work he presented his new theory of epigenesis that gave the death-blow to the entire theory of preformation.
