Admiral Evelyn Fields
Evelyn Fields was not afraid to take risks—a characteristic that brought her a few “firsts” in her NOAA Corps career, including becoming the first woman and first African-American to hold the position of Director of the NOAA Corps and Office of Marine and Aviation Operations. She was also the first (and so far, only) woman to reach the rank of rear admiral in the NOAA Corps.
