What white people were important during the civil rights movement?

Some of the prominent whites who I learned about were Viola Liuzzo who died in Alabama driving civil rights activists throughout the state and was murdered by the Klan. Ann Braden in Kentucky dedicated her life to the work of Civil Rights and has left a legacy behind to continue that work. I also know of a white man from Michigan who had only one leg and marched the whole distance of the Selma to Birmingham March in 1966, Jim Letherer.

Presidents Kennedy and Johnson were very important during the Civil Rights movement.
