On Dec. 23, 1919, inventor Alice H. Parker of Morristown, New Jersey, patented her design for the gas heating furnace. Parker’s design would help provide central heating in millions of homes and buildings around the world today.
Parker’s gas heating furnace revolutionized how people heat their homes. With her invention, people no longer needed to stock and burn wood in a traditional furnace, which presented a high fire risk when left unattended.
