Erwin Rudolf Josef Alexander Schrödinger (; 12 August 1887 – 4 January 1961), sometimes written as or , was a Nobel Prize-winning
Austrian physicist who developed a number of fundamental results in the field of
quantum theory, which formed the basis of wave mechanics: he formulated the
wave equation (stationary and time-dependent
Schrödinger equation) and revealed the identity of his development of the formalism and
matrix mechanics. Schrödinger proposed an original interpretation of the physical meaning of the
wave function.
