There are many legends in medicine, and Dr. Howard Tucker can easily be counted as one.
For 75 years, the Cleveland neurologist watched an evolution in medicine unfold, but he'll be the first to tell you we haven't even scratched the surface.
"There are oceans beyond our understanding," he says.
Tucker graduated from the Ohio State University College of Medicine in 1947, and later served as a Navy neurologist during the Korean War for the Pacific Fleet. When he began his practice, CT scans and MRIs were science fiction.
Tucker used his ears and brain to solve patient problems like a life-saving puzzle. Some cases earned him accolades.
"It's a delusion that I was infallible," he humbly told us. "Just because you saw one case doesn't mean you're a star."
These days, you can still find him in the halls of St. Vincent Charity Medical Center, teaching neurology residents the art he's not only mastered, but continues to learn. Asked what the most important thing he's taught his students is?
"Funny enough, how to take a history and come away with an answer before you examine the patient," he answered. "That's the critical part of neurology, or having fun in medicine."
