Charles McGruder III

Charles H. McGruder III is an African-American astrophysicist, researcher and professor at Western Kentucky University, where he holds the William McCormack Endowed Chair in Physics and Astronomy. In 1961, McGruder enrolled as a California Institute of Technology freshman, and was the second African American undergraduate at Caltech. McGruder received his Bachelor of Science in Astronomy from the California Institute of Technology. Soon after completing his Bachelor's program, he received his Ph.D. in Astrophysics from the University of Heidelberg, Germany in 1972. After completing his doctoral studies in Germany, McGruder embarked on a journey across Africa. This adventure led him to a lectureship position at the University of Nigeria. He might have settled there for the long term, but a condition set by his future father-in-law altered his plans. McGruder had to return to the United States with his daughter if he wished to marry her. During his time, he was very involved in improving the physical condition of the African continent as president of the NSBP International Committee. He was a very important figure in the development of the African Astronomical Society.

McGruder III and Wieb VanDerMeer, B. wrote "The 1916 PhD Thesis of Johannes Droste and the Discovery of Gravitational Repulsion" which provides the translation of the concept of gravitational repulsion that was first introduced by Johannes Droste in his Ph.D. thesis submitted to H.A. Lorentz in 1916.

Personal and social impact

In a reflective interview at the California Institute of Technology, Charles McGruder III discussed the impact of various factors, including integration, on his life and career. McGruder, raised in Bristol Township, shared insights into his upbringing influenced by his parents—a doctor and a sociology student—who met at Howard University. He recounted experiences navigating racial dynamics both in the North and South, citing his father's prominence as a physician. McGruder also highlighted his academic journey, mentioning early exposure to science through books and an astronomy club, which fueled his passion for exploration and discovery despite facing biases from some instructors.

In another part of the interview, McGruder discussed the role of the National Society of Black Physicists (NSBP) in his professional development. He described his initial encounter with a Black physicist while traveling through Africa, which led to his involvement with NSBP in 1990. McGruder emphasized the importance of NSBP in fostering a sense of community and support for Black physicists, comparing it to his involvement with the American Physical Society (APS) Committee of Minorities. He reflected on NSBP's evolution, highlighting its focus on mentorship and the development of the next generation of physicists. McGruder stressed the significance of inclusivity and representation, particularly through role modeling and mentoring, in empowering aspiring physicists of color.
