1831 – 1879
James Clerk Maxwell (1831–1879) was a Scottish physicist and mathematician whose formulation of classical electromagnetic theory unified electricity, magnetism, and light into a single theoretical framework. His work laid the foundation for modern physics and directly influenced Einstein's development of special relativity. Maxwell also made foundational contributions to the kinetic theory of gases and statistical mechanics.
Formulated Maxwell's equations, unifying electricity, magnetism, and optics
Predicted the existence of electromagnetic waves and identified light as one
Developed the Maxwell-Boltzmann distribution in statistical mechanics
Produced the first durable color photograph (1861)
Introduced Maxwell's demon thought experiment, challenging the second law of thermodynamics
