Cardiologist David Chomsky, MD, of Elkins Park, Pennsylvania, has died from cancer. He was 86 years old.

Chomsky began his career in healthcare after graduating from Temple University medical School in 1959. He made house calls until he was 85, only stopping in 2020 due to the COVID-19 pandemic.

According to the thorough obituary printed in the Philadelphia Inquirer, he was even asked once by the federal government to stop performing house calls for his own safety—but he refused.

Loved ones also remembered Chomsky’s love for dogs. He trained them to become therapy animals and would regularly take them along when he visited patients.

Chomsky’s older brother is Noam Chomsky, the famed philosopher, scholar and linguistics expert.

“My most salient and enduring memories of my little brother are from wonderful days of childhood, when we were almost always together,” Noam Chomsky said in a statement to the Inquirer.
