1868 – 1957
Gustav Mie (1868–1957) was a German physicist known primarily for his contributions to electromagnetic theory and early attempts to develop a unified field theory of matter. His work engaged deeply with the foundations of relativity, including philosophical questions about measurement and the ontological status of rigid bodies and clocks in spacetime physics.
Derived the Mie solution to Maxwell's equations describing light scattering by spherical particles
Developed an early nonlinear field theory of matter (Mie theory of matter, 1912-1913)
Contributed to foundational debates on measurement in general relativity
Advanced the concept that physical mensuration need not presuppose rigid bodies and clocks
Influenced Hilbert and Weyl in their work on unified field theories
