Jack Brownstein was more than just a teacher. He was a friend to many of his students at the University of St. Thomas.
Polar explorer Will Steger, of Ely, Minn., was one of them.
"He was an inspiration as a teacher and became a personal friend throughout my life," said Steger, who is known for his expeditions to the North Pole and Antarctica.
Brownstein, who was named professor of the year in 1998 and credited with starting many programs at the university, died Sunday of cancer at his home in St. Paul. He was 62.
Steger said he changed his major to geology because of Brownstein.
"I'm a person who loves the outdoors, so the way Jack taught it had a lot to do with it, especially with a man like this at the head of the department," he said.
Paul Lane, a physics professor and longtime friend, credited Brownstein with starting the Geology Department. "He was a force at the University of St. Thomas," he said. "He built up the program to be a success."
In his 38 years at the university, he taught more than 7,000 students, 135 of whom were geology majors. Of the 135, 60 percent went on to earn graduate degrees, and 70 percent work in geology.
