Since 1973, the Tyler Prize for Environmental Achievement has been bestowed upon people who have made a significant impact in the fight for a sustainable planet. In 2019, we spoke with that year's Tyler Prize Laureate, Warren Washington, to learn about the beginnings of his groundbreaking career as an atmospheric scientist. This week on Sea Change Radio, we pay tribute to Dr. Washington, who recently passed away at the age of 88. He was the second African American to receive a PhD in meteorology, a former chair of the National Science Board, and a senior scientist at the National Center for Atmospheric Research in Boulder, Colorado. Then, we revisit part of our conversation with physicist Hattie Carwell to learn about her long, illustrious career in the atomic energy space as well as her work at the Museum of African American Technology.
