Summary from Wikipedia

Leopold Sonnemann was born to Jewish parents in Höchberg, Bavaria, in 1831.[2] Well-educated in his youth, he became an astute businessman and organizer. He built upon his family business and amassed enough wealth by 1856 to purchase a Bavarian market publication, the Neue Frankfurter Zeitung. Rechristening it to simply Frankfurter Zeitung, Sonnemann devoted himself wholeheartedly to the paper as owner, editor, and contributing writer.[2] The paper developed an influential position in the business community of southern Germany.[3]
