Hubert Mack Thaxton (20 March 1909 – 3 January 1974) was an American nuclear physicist, mathematician, engineer, and the fourth African American person to earn a PhD in physics in the United States. Thaxton's research focused on proton scattering, which at the time was a largely unexplored area of study. [1] [2]
