Career and Contributions
Planetary Studies to Atmospheric Research His curiosity pushed him from planetary studies during the space race to deep investigations of Earth’s atmosphere.
Kitt Peak National Observatory Created a theory describing upper atmospheres, earning the 1968 James B. Macelwane Medal for early career researchers.
Harvard University Joined Harvard at age 31, becoming one of its youngest tenured professors.
Ozone Depletion Research Worked on ozone depletion, linking bromine and nitrous oxide to the rapid formation of Antarctica’s ozone hole. This research helped shape the Montreal Protocol, a global treaty that phased out harmful chemicals.
