Which black man invented the fountain pen?

The fountain pen was invented by Lewis Waterman, an African American inventor, in the late 19th century. While Waterman is often credited with improving the design and functionality of fountain pens, it is important to note that he was not the sole inventor of the fountain pen concept, which had earlier iterations. His design, patented in 1884, incorporated a more reliable ink flow mechanism, which made fountain pens more popular and practical.
