He was a very soft spoken Professor and was in the senior staff when we joined NED. It was hard to hear him at the back of the room, so whenever he entered the class he would close the door in this way he discouraged not only late comers but kept the outside noisy away. He would silently enter the class without a sound and most of the time we would not know that he is present until the door closed and lights turned on.
He made sure that girl student sit in front bench alone , so the whole bench was reserved for the only girl student while boys had to crammed together, If any boy was brave enough to sit on the edge of this bench he would ask him to move, no one dared to sit on that particular bench in his class.
He was a very knowledgeable lecturer and knew his subject well, He had a funny way of looking at the students by bending his neck and looking over his glasses .,,,a deep look enough to chill your blood.
Prof A T Khan was one of the best teachers we had. He taught us Surveying in the first year. Later we took Soil Mechanics course from him. In the final year he taught Transportation Engineering. I beieve he had pursued graduate studies in Soil Mechanics and particularly enjoyed teaching this course. I still recall some of the key concepts he had taught in the Soil Mechanics course. He later became the Chancellor of the NED Univerity.
Prof Khan was a very soft-spoken person and sometimes he was barely audible to the back of the room. The soft mannerism occasionally gave way to cutting words. I recall that during the first year we had to prepare a survey map of a field survey we had done. We were all queued up to get our work assessed by Prof Khan. Ahead of me was Nawal Rai (C70). As I looked at his drawing I envied the beautiful work visible. He had taken the title block and decorated it in quite an ornamental way. When his turn came, he laid the drawing before the professor who took one look, stood up, held the drawing up pointing to the title block and said: "We are engineers, not artists". I felt so embarrassed for Nawal Rai.
In 1966, ours was the third batch where girls were admitted. There was a group of conservative teachers who remained opposed to the idea of including girls. While Prof Khan never openly expressed his opposition, there were subtle signs that he had reservations the girls being admitted. Perhaps Jamila (C70), Naheed (C69), or Asifia (C68) might want to comment on this?
