James M. Bardeen is an American theoretical physicist renowned for his contributions to the fields of cosmology and general relativity. He is particularly well-known for his work on black holes, including the formulation of the "no-hair theorem," which suggests that black holes can be fully described by just three observable properties: mass, electric charge, and angular momentum. Bardeen also made significant contributions to the understanding of the early universe and the inflationary theory of cosmology.

James M. Bardeen developed methods for interpreting motion near rotating black holes. His 1972 paper with William H. Press and Saul Teukolsky introduced a practical local-frame treatment for particle orbits and radiation in the Kerr metric.
Locally nonrotating observers provide an orthonormal frame tied to the rotating geometry. Expressing measurable quantities in that frame clarifies which effects reflect local motion and which involve frame dragging.[ref]
