The James B. Macelwane Medal is given annually to three to five early career scientists in recognition of their significant contributions to Earth and space science. Nominees are selected for the medal based on their depth and breadth of research, impact, creativity, as well as service, outreach, and diversity.

 

The Macelwane Medal was named in honor of former AGU president James B. Macelwane (1953-1956) who was renowned for his contributions to geophysics. Macelwane was also deeply interested in teaching and encouraging scientists, founding the Department of Geophysics at St. Louis University and serving as Dean of the Graduate School, along with various other roles, all while always committing to teach at least one course.
