There are many people who have earned more than one PhD, but the person with the most PhDs is Dr. David Lewis Anderson. As of 2018, he has earned 23 degrees, the majority of which are in engineering and science. He also has a law degree and several honorary doctorates.
Dr. Anderson's love of learning began at a young age. He started college at just 16 years old and went on to earn his first PhD by the time he was 22. Since then, he has continued to add to his impressive list of credentials, including degrees from such prestigious institutions as Harvard, MIT, and Yale.
While some may view having so many degrees as overkill, Dr. Anderson sees it as a way to continually expand his knowledge base and keep himself challenged intellectually. For him, there is no such thing as too much education!
