Major Geoffrey Langlands. Favourite anecdotes:

So far, this is mine: "He promoted the poor of Chitral," Farhat Tamas, a professor of psychology at Peshawar University, said. "I clearly remember the first day I went to school. I was wearing old clothes and two different slippers on my feet because my parents had no money to buy me books or a school uniform. But Major Langlands encouraged me and taught me how to live a happy life." "When I got this teaching job at Peshawar University, I took sweets for Major Langlands. He distributed those sweets among girl students, saying he wanted every one of them to bring him sweets one day."

Isn't that amazing?
