In 1828-29, Braunhart was teaching at the private houses of distinguished Jewish families in London. He was appointed principal of the Jewish school in Schubin in 1835. Two of his well known students included Moses Mielziner, who was born in Schubin and later became a well-known American Reform rabbi and author, and General von Wittich.
Later in life, Braunhart was awarded the German equivalent of knighthood by Emperor Wilhelm I, and became known as Ritter von Braunhart.
He married Minnie Zadek on February 3, 1836. There are 3 known children, and probably there are more. There were quite a few Braunharts in Schubin at the time; several of whom are not known as to their exact relationship. The three known children were Bernhard Braunhart, Sara Braunhart, and Samuel Braunhart. All emigrated to the United States. There is a fourth child, Alex Braunhart, who I am researching, but have as yet not confirmed.
Many thanks to my "cousin" Maxine Rudy, who provided the inspiration for the research for L. J. Braunhart. She claimed that his name was "Ritter von Braunhart". I was skeptical because I knew from his daughter's death certificate, his name was Jacob Braunhart. But she was right!
