famous people

Overheard in the hallway outside my classroom:
Student, referring to pictures on a bulletin board: "Look, there's Obama!"
Teacher: "President Obama. Do you recognize anyone else?"
Student: "...................................."
Teacher: "This is Martin Luther King, Jr. And this is George Washington Carver, who gave us peanut butter. Isn't that great? And this is a nurse."

I'm glad that there is a bulletin board in the hallway depicting famous African Americans during Black History Month. But aren't there individuals that impacted our world in more important ways than creating peanut butter and a nameless nurse? Who would be on a bulletin board celebrating European Americans? Or Asian? Or Hispanic?
