87 years old (Born on May 17, 1937)
Happy Birthday, Hazel R. O'Leary! You truly energized history as the first African American and woman to serve as U.S. Secretary of Energy—proving once and for all that your power source is unstoppable determination (and maybe a little caffeine). Your groundbreaking tenure from 1993-1997 illuminated pathways in energy policy we still follow today.And let's not forget your inspiring leadership at Fisk University from 2004–2012, where you charged up generations of students with wisdom brighter than any LED bulb could ever shine. May this birthday be filled with laughter, joy—and absolutely no talk about conserving cake calories!
