Pascual Jordan

<p>Ernst Pascual Jordan (German: [ˈɛʁnst pasˈku̯al ˈjɔʁdaːn]; 18 October 1902 – 31 July 1980) was a German theoretical and mathematical <a href="/facts/Physicist/cQcgvSIm">physicist</a> who made significant contributions to <a href="/facts/Quantum_mechanics/BRc3Mzgr">quantum mechanics</a> and <a href="/facts/Quantum_field_theory/VoewsNJV">quantum field theory</a>. He contributed much to the mathematical form of <a href="/facts/Matrix_mechanics/nJxC4pKP">matrix mechanics</a>, and developed <a href="/facts/Quantum_field_theory/VoewsNJV">canonical anticommutation relations</a> for <a href="/facts/Fermion/LEckdDsR">fermions</a>. He introduced <a href="/facts/Jordan_algebra/4BBGsQd9">Jordan algebras</a> in an effort to formalize quantum field theory; the algebras have since found numerous applications within mathematics.
</p><p>Jordan joined the <a href="/facts/Nazi_Party/qQCramHd">Nazi Party</a> in 1933, but did not follow the <a href="/facts/Deutsche_Physik/8ux3V9kS">Deutsche Physik</a> movement, which at the time rejected quantum physics developed by <a href="/facts/Albert_Einstein/CNTet8qu">Albert Einstein</a> and other Jewish physicists. After the <a href="/facts/World_War_II/2efV5L1U">Second World War</a>, he entered politics for the conservative party <a href="/facts/CDU/CSU/e75o7Dyj">CDU</a> and served as a member of parliament from 1957 to 1961.
