萨克森-迈宁根
Schönfeld was born at Hildburghausen, in the Duchy of Saxe-Meiningen, where he had a distinguished career at the gymnasium. On leaving the gymnasium, he desired to devote himself to astronomy, but abandoned the idea in deference to his father's wishes. He went first to Hanover, and afterwards to Kassel to study architecture, for which he seems to have had little inclination. 1849 found him studying chemistry under Bunsen at Marburg, where his love for astronomy was revived by Gerling's lectures.
