Charles S. Lewis Baker (Charles S. L. Baker) is an African American inventor who’s ingenuity led to the perfection of home heating systems via the radiator. He was born on August 3rd, 1859, in Savannah, Missouri. While he may or may not have invented the the radiator itself, Baker worked over the span of decades on his product, attempting several different forms of friction, including rubbing two bricks together mechanically, as well as using various types of metals. After twenty-three years, the invention was perfected in the form of two metal cylinders, one inside of the other, with a spinning core in the center made of wood, that produced the friction. Baker started a business with several other men manufacturing heaters. The Friction Heat & Boiler Company was established in 1904.
