If lifetime impact could be quantified by pages in The Cancer Letter, no person has been more revered than Waun Ki Hong: following Hong’s death in 2019, The Cancer Letter published no fewer than six obituaries. Now, you can hear his story in his own words. “Waun Ki Hong’s contributions to medicine changed the field as we know it,” wrote Fadlo R. Khuri, president of the American University of Beirut. Hong died Jan. 2, 2019. On Jan. 4, The Cancer Letter published three obituaries, but they kept coming.
