James Rothenberger of Minneapolis, who served on the faculty of the University of Minnesota School of Public Health, was a popular teacher who taught a broad range of courses while facing serious illness for 23 years.
During his career, he endured two kidney transplants, but still taught more than 100,000 university students.
Rothenberger, 61, died Dec. 8 in Minneapolis of complications from kidney disease and an infection.
He grew up in Deephaven and graduated from high school in Rochester, N.Y. In 1969, he earned a bachelor's degree in political science at the University of Minnesota.
In the early 1970s, he served as a consultant on drug abuse prevention in the Nixon White House. He returned to the university, completing a master's degree in public health in 1979.
He was an innovative teacher and leader of public health programs on campus and off, said John Finnegan of St. Paul, dean of the University of Minnesota School of Public Health.
Finnegan called him an "amazing guy" and "a remarkable teacher," who taught more courses than most --15 a year.
"Jim was just a machine," he said. "He built an excellent cadre of teaching assistants."
