John H. B. (John Hazlehurst Boneval) Latrobe

John Hazlehurst Boneval Latrobe was an American lawyer and inventor. He invented the Latrobe Stove, also known as the "Baltimore Heater", a coal fired parlor heater made of cast iron and that fit into fireplaces as an insert. He patented his design in 1846. The squat stoves were very popular by the 1870s and were much smaller than Benjamin Franklin's Franklin stove.
