Audiology professor Frank Lassman left his office at the University of Minnesota each month to go to institutions such as a school for the deaf in Faribault in search of children whose hearing loss had been misdiagnosed.
He helped some get back to their families after rehabilitation. Others were obviously misdiagnosed.
"There were some examples where the patient would have been institutionalized because they thought there were insane. Instead, they had a hearing problem, and he helped them get back closer to a normal life," said Dr. Michael Paparella, chairman emeritus of the U's Department of Otolaryngology, Head and Neck Surgery.
Lassman, of Minneapolis, died April 24 at University of Minnesota Medical Center. He was 93.
He worked 62 years at the U, including as chief of audiology, a program within the Department of Otolaryngology, a specialty that pertains to the ear, nose and throat. Lassman taught and researched audiology — the science of measuring a person's hearing — and saw many patients.
Quiet and dignified, he also coordinated services for the mentally ill, handicapped and elderly.
"He was an advocate for the people who had not always been dealt the best hand in life," said longtime friend Rodney Loper, a retired U psychology professor. "He cared about people getting a chance in life, and he didn't want to see people sidelined due to age or disability."
For 21 years, Lassman served on the board of Tasks Unlimited, a Minneapolis nonprofit that provides housing and recovery services for those with mental illness.
