Sgt. Philip Kahn was born in 1919 during the flu pandemic that killed 50 million people worldwide, including his twin brother weeks after birth. Kahn died last week at 100 years old due to the coronavirus. He served during World War II in the United States Army Air Force as an engineer and co-pilot, earning two Bronze Stars. He later became an electrical foreman and helped build the World Trade Center in his hometown of New York City. Sunday TODAY’s Willie Geist remembers a life well-lived.
