Jacob Brosius was a mechanic and an inventor who came directly to Belleville in 1849. His products reflect the hand of man. He held at least 7 patents for agricultural equipment improvements and 3 for radiators and steam conducting pipes. His foundry and machine shop was prosperous, and his castor, linseed and pecan oil business was even more so. In 1876, he built a very pretentious, palatial style home on a hill overlooking east Belleville. He called it “Kronthal”. In 1879, he built the works for heating the City. His “Electric Clock” located in his residential tower was connected with other public clocks in the City. He died in 1882, age 59.
