Of the attack, Williams was quoted as saying, "I was deemed 100 percent disabled by the military and required a cane to walk. My wounds had earned me a Purple Heart. The war had just ended and I was "still in my uniform" for god's sake! But on my way home, to the brink of death, they beat me like a common dog. The very same people whose freedoms and liberties I had fought and suffered to secure in the horrors of war ... they beat me like a dog ... merely because I wanted a drink of water." He went on to say, "I had watched my best buddies tortured, murdered, and bodies blown to pieces. The French battlefields had literally been stained with my blood and fertilized with the rot of my loins. So at that moment, I truly felt as if I had fought on the wrong side. Then, and not until then, did I realize why God, time after time, had taken me to death's door, then spared my life ... to be a general in the war for human rights and personal dignity." After the war, he earned a high school diploma at the age of 23, then a bachelor's degree and a master's degree (both in chemistry) from Atlanta's Morris Brown College and Atlanta University (present-day Clark Atlanta University). Williams was a member of Phi Beta Sigma fraternity. Williams' birthday coincided with the anniversary of the death of one of that organization's most prominent members, George Washington Carver. After college, Williams worked for the United States Department of Agriculture as a research scientist.
