Erwin Schrödinger (1887-1961) was an Austrian theoretical physicist who developed wave mechanics, one of the central formulations of quantum mechanics.

Wave mechanics

Schrödinger introduced the wave equation that bears his name in 1926. The equation describes how quantum states evolve and became a foundation for atomic, molecular, and condensed matter physics.

His wave mechanics was soon shown to be equivalent to Heisenberg's matrix mechanics, giving quantum theory two complementary mathematical forms.

Foundations

Schrödinger also introduced the famous cat thought experiment to criticize simple readings of quantum superposition and measurement. The example remains important in discussions of measurement, decoherence, and macroscopic quantum states.
