Sincere condolences to the Family I’m not positive I have the right Mr Knauff. Did Mr Knauff teach at Mark West Union Elementary in Fulton CA? If so he was my teacher for a year or so 1952/1953. I believe he was also the principal. He did indeed have red hair. Great teacher. I remember him and Mrs Lee from Mark West Union. Again, my sincerest condolences. Sharon Cooper
