Meet the Centenarian Neurologist, Dr. Howard Tucker

Dr. Howard Tucker, a Cleveland-based neurologist, has become an international symbol of healthy aging and professional purpose. Born on July 10, 1922, he was officially recognized by Guinness World Records as the oldest practicing doctor. His remarkable career began in 1947, and he continued to see patients for nearly eight decades before transitioning his role. Even after officially stopping patient visits around his 100th birthday, he has remained an active and contributing member of the medical and legal communities, frequently lecturing and consulting on cases well into his 102nd and 103rd years. His story is a powerful testament to the value of lifelong learning and engagement in one's profession.

He later established a long and successful career in Cleveland, where his expertise led him to solve a notable medical mystery involving two young girls who were in and out of comas. The case, which received national media attention in the 1960s, cemented his reputation in the medical field. His dedication to learning also led him to pursue a law degree at the age of 67, passing the Ohio bar in 1989.
