One of the best Marines I ever knew was one Corporal Butler who came from Watts and nearly all of his family was in jail or on probation while he served in the Corps. He defied the stereotypes. He was my brother. We were one color when it counted — Green. You will never hear about him in the history books, nor will you see him on TV, but he was an outstanding American and a true patriot.
One of the BYU campuses has a course where they include the study of Frederick Douglass...so, hey...at least a few BYU students -- had they been interviewed...would have included him.
You'd think others could have named somebody like George Washington Carver...or at least Jackie Robinson...
FYI: Lesser known but mentionables could include contributors like...
...Dr. Daniel Hale Williams, who performed the first successful open heart surgery back in 1893!
...Or James West, who netted 200 patents...one leading to about 90% of microphones in use today being based upon an invention of his...
...many others...
