Ernst Ising’s analysis of the one-dimensional variant of his eponymous model (Z. Phys 31, 253–258; 1925) is an unusual paper in the history of early twentieth-century physics.

In 1924, Ernst Ising thought he showed a simple model for ferromagnetism couldn't work. 100 years later, that model, now named for him, is used across all of physics.

The two-dimensional square-lattice Ising model is one of the simplest statistical models to show a phase transition. [1] The Ising model was invented by the physicist Wilhelm Lenz (1920), who gave it as a problem to his student Ernst Ising.
