Can you tell me why these names are important to our world?

Sir Henry Bessemer

William Kelly

Robert Forester Mushet

Sidney Gilchrist Thomas

"Steel" guessing?

They all contributed to the ability to mass produce steel and create other metals we use in manufacturing products used in everyday life. Yet, their names don't come up in everyday life. So many men and women of the past are not given enough credit for very important necessary inventions and work performed while so many men and women of the present are overly credited for unnecessary things like TikTok poses and rants making much ado about nothing. I still hope or dare it be said "steel" hope we can honor those who do important things more than those who do not. It's time to remember to be more thankful, thoughtful and true to what really matters as opposed to what does not.
