Con de Villiers died on 25 November 1978 at his nephew's house in Ceres.
To me Dr. Con was the perfect mentor. He gave a direction to my life by teaching me to look, listen and think.
(Hy) was a magtige gewer in my lewe. Nou eers verstaan ek wat hy bedoel het toe hy gesê het: "Die Afrikaner deug net in die woestyn ". Net woestynomstandighede, so lyk dit my vandag, kan die mens van sy hubris en opportunisme verlos.
