It was Thurgood Marshall who ended legal segregation in the United States. He won Supreme Court victories breaking the color line in housing, transportation and voting, all of which overturned the 'Separate-but-Equal' apartheid of American life in the first half of the century. It was Marshall who won the most important legal case of the century, Brown v. Board of Education, ending the legal separation of black and white children in public schools. The success of the Brown case sparked the 1960s civil rights movement, led to the increased number of black high school and college graduates and the incredible rise of the black middle-class in both numbers and political power in the second half of the century.
