About this episode: June 8 would mark the 80th birthday of Dr. Levi Watkins, Jr., a cardiothoracic surgeon at Johns Hopkins known for being part of the first team to implant an automatic defibrillator in a human patient. But Dr. Watkins was so much more: a civil rights and political activist, a champion of Black and other people who are underrepresented in medicine, and a snappy dresser with a great sense of humor. Today, two people who knew and worked with Dr. Watkins share their memories as we celebrate his legacy.
Guests: Dr. Lisa Cooper is a public health physician, a Bloomberg Distinguished Professor, and a faculty member at the Johns Hopkins Bloomberg School of Public Health and School of Medicine.
