Mr Graham was my teacher for homeroom, Calculus, Advanced Algebra & Analytical Geometry my senior year at AHS (class of 1967). I have fond memories of him dancing around in front of the chalkboards with a twinkle in his eye, solving problems, saying "Isn't this fun!?" He was one of the outstanding teachers of my life. I'm confident my twin brother agrees. I regret I live too far away to attend his service. Condolences to his family and loved ones. Decades of appreciative students love math thanks to Mr Graham.
