No, the air conditioner was not invented by a Black man. Willis Carrier, a white American engineer, is credited with inventing the modern air conditioner in 1902.
The modern incandescent light bulb was invented by Thomas Edison in 1879. While there were earlier versions of electric lights developed before Edison's, his design was the first practical and commercially successful one.
Yes, Frederick Jones, a black inventor, patented an air conditioning unit for refrigeration systems in 1949. His invention revolutionized the transportation of perishable goods and improved the comfort of buildings, vehicles, and more.

Nope. It was a white guy. Martin Cooper in 1973. Nor did a black man invent the air conditioner, peanut butter, ice cream, traffic light, and a host of other poorly researched self esteem building myths that pop up in schools and local news pieces every February!

HE WAS THE FIRST BLACK MAN THE INVENT NEW FLAVORS OF ICE CREAM.
