I have some interesting info on Dr.Stewart.
Ali Khan

I studied at Gordon College during 1957-59. At that time Mr Daskawie was the principal of the college and, I think, Dr R.R. Stewart was the vice-principal. I remember Dr Stewart as a short man with grey hair, sometimes moving around on his bike. He was a soft-spoken man. Some of my teachers I met there have had a lasting effect on my educational career. I would like to mention the names of Yusuf Jalil, Daniel, Rais Ahmad Khan, Nasrullah, Yunus Masih, Xavier, Siddiq Cheema. They were great teachers and I have never seen a place as Gordon College was again anywhere in Europe.

I shall be much obliged to anyone who can give me some information on any of the teachers I mentioned in my earlier comment. I can be contacted at my Website: http://nasir-khan.blogspot.com) or kh888n at hotmail dot com
