Art was Robert Paul's passion; teaching was his life. He merged the two as a reserve teacher at Minnetonka High School.
But as a reserve teacher for 20 years, he was just as likely to teach AP calculus, history or English. And for thousands of Minnetonka High School students, Paul became known as the "Trusty Reserve."
"It was his life," said his wife, Lizz. He quit teaching only when health issues sidelined him last fall, shortly after he turned 80 years old, she said.
On Tuesday, Paul died of natural causes in his Minnetonka home.
Growing up in South Dakota, Paul began teaching in Sioux Falls, S.D.
The Army put his career on hold while he served in Korea from 1951 to 1953. Once back in the United States, Paul earned his graduate degree from the University of Iowa and began work on a doctorate.
But as a father of one young child and with another on the way, Paul took his professor's advice to get out into the field and teach. He never looked back, his wife said.
Paul taught junior high school for seven years in Newton, Iowa, before moving to Minnetonka in 1964 to develop and coordinate a K-12 program to help teachers bring art into the classroom.
