When Husain Sattar, MD, took a leave of absence from medical school to study Arabic and Islamic spirituality in Islamabad, Pakistan, he spent his days in a classroom that had walls made of clay and would heat up to 120 degrees in the summer. In the winter, the unheated classrooms were freezing — Islamabad sits at the foothills of the Himalayas — and Sattar, who was born and raised in the Chicago suburbs, sat on the floor with the other students shivering and dreaming of summer.
It was a far cry from the University of Chicago, where he earned his undergraduate and medical degrees and later did his internship, residency and fellowship. Besides the lack of creature comforts, his instructors did not have fancy diplomas from prestigious universities. But there was a Pakistani teacher who made an impression on Sattar — one that planted the seed for Sattar’s wildly successful textbook and video series on pathology known as Pathoma.
“This teacher always came to class without notes,” Sattar said, recalling the instructor with the gray beard who smiled often and dressed in the traditional Pakistani garb of loose pants and tunic-like shirt. “He would say, ‘If I can’t tell you about it from the top of my head, then I shouldn’t be telling you about it at all.’” The man lectured passionately, as if there were 3,000 people in the room instead of eight, but what the young American medical student found most impressive was his skill distilling colossal amounts of material. “He had this ability to take vast amounts of information and summarize it in the most eloquent, simple, principle-based method,” Sattar said.
