Myron Mathisson

Myron Mathisson (4 December 1897 – 13 September 1940) was a Polish theoretical physicist who made early contributions to the theory of general relativity, particularly in the motion of spinning bodies and the analysis of hyperbolic partial differential equations. His work on the equations of motion for extended bodies influenced later formulations such as the Mathisson–Papapetrou–Dixon equations, and he made progress on aspects of the Hadamard conjecture in specific cases.
