Alice H. Parker Invented The Central Heating System

Alice H. Parker was an African American inventor known for her patent for a gas furnace. She grew up in New Jersey, where winters are cold. It was said that because the fireplace didn’t provide enough warmth, she was inspired to search for a better heating solution. While many people at that time were using wood and coal, Parker thought of a gas furnace using air ducts to distribute the heat to all parts of the house. The patent was issued in 1919 and although it was not the first gas furnace design, it was the first to contain individually controlled air ducts to transfer heat to different parts of the building. The invention was never implemented due to safety concerns, because you couldn’t control the heat flow, but it led the way to modern central heating systems.
