"She may not be here with us tonight, but you know ... I feel like she is here," Moll said.
Members of the class of 1967 were responsible for starting the first intensive care unit in Ottumwa.
"Before 1968, there were no ICUs in hospitals," said Susan Bay, who launched Ottumwa's ICU alongside Jeanie Morrison.
The pair was sent to Denver to learn how to take care of patients who had had heart attacks or been severely injured.
"We were there two weeks and worked at Colorado General Hospital," Morrison said. "We defibrillated a dog to learn how to do it."
They returned to Ottumwa, where they worked with the doctors to set up the ICU and a coronary care unit.
