Light bulbs were around long before that, Edison's lab just made one that worked in a useful way. What I find funny about the whole Lewis Howard Latimer thing is woketards are willing to ignore actual accomplishments from black men so they can push agendas. Can't celebrate that some dude figured out how to make carbon filaments that made mass lightbulb production possible, we have to put up statues to a rapist that couldn't breef.
