With sadness I read that my old Chemistry teacher from Scotch College had passed away. Ken taught me in Form 5 and Form 6 back in 1984 and 1985. I had difficulty with Chemistry but Mr Mappin encouraged me greatly and he was a teacher that was always friendly and patient. Even though I failed HSC Chemistry by 1 mark, I went onto gain a credit in a chemistry subject for my viticulture degree.I think Ken would have been proud. My sincere condolences to Mr Ken Mappins family. Craig Mac Kenzie
