Erwin Rudolf Josef Alexander Schrödinger (German:[ˈɛɐ̯viːn ˈʃʁøːdɪŋɐ]; 12 August 1887–4 January 1961), sometimes written as Erwin Schrodinger or Erwin Schroedinger, was a Nobel Prize-winning Austrianphysicist 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.
