Latimar made improvents to the carbon filaments in the lightbulb. This made it more durable and cost efficient and is the bases of the type of lightbulbs we use now.
So no, he never invented the lightbulb, that was Edison.
Biden is clearly pandering and didn’t even think to mention Lewis Latimar by name, instead of calling him a “Black man”.
Latimar was a brilliant man and was also in the Navy, pity men like him aren’t discussed in the History class. It seems the curriculum mentions Slavery, Jim Crowe and MLK and concludes “Black history” right after. That needs to change.
