“Before modern heating systems became commonplace, a Black inventor was imagining a better way to keep homes warm.
Her name was Alice H. Parker.
On December 23, 1919, Parker received a U.S. patent for an innovative gas-powered heating furnace. Her design featured multiple independently controlled heating units and a duct system that could distribute warm air to different rooms or floors.
At a time when many households relied on wood-burning stoves and fireplaces, her concept offered a different approach to heating homes. The ability to regulate heat in separate areas was especially forward-thinking.
Although Parker’s exact design never entered commercial production, her work is recognized as an important precursor to modern zoned heating systems.
Remarkably, much of Parker’s personal history remains undocumented. Her story is also a reminder of how easily the contributions of Black women inventors can be overlooked in the history of innovation.
She may not have built the heating systems we use today, but her patented design deserves its place in the conversation about the people who helped shape them.
Black history is also the history of innovation, ingenuity, and ideas that challenged the limits of their time.
