Dr. Samuel Hall, who helped found the first state-wide poison control center in Minnesota, took action when he saw a need in the community.
Hall, 64, served at Regions Hospital in St. Paul and the Veterans Medical Center in Minneapolis.
He died July 19 at his Shoreview home. He had been recuperating from a stroke suffered in December.
New ideas in medicine often encounter resistance from professionals who claimed it was "impossible" to do, said Dr. Wesley Miller, interim chairman of medicine at the University of Minnesota Medical School.
"Sam would see something" others did not, said Miller. "If it was a good idea, he would find a way to do it."
Cofounding the former Minnesota Regional Poison Control Center was an example.
"He forged the legislation to allow it to happen," said Miller.
Hall grew up in Illinois and graduated from Northwestern University's Medical School in 1970. He served as a Navy doctor for a few years and came to the University of Minnesota for a residency in internal medicine, completing it in 1976.
