-
J.J. Thomson was born
-
Marie Curie and Pierre Curie, discovered and isolated radium and polonium (1898). Studied radioactivity of uranium. And won the Nobel Prize in 1903 (with Becquerel) in physics; in chemistry 1911.
-
Marie Curie was born
-
Ernest Rutherford discovered that uranium radiation is composed of positively charged 'alpha' particles and negatively charged 'beta' particles (1989/1899). First to prove radioactive decay of heavy elements and to perform a transmutation reaction (1919).

-
Erwin Schrödinger was born
-
Discovered radioactivity of uranium (1896) and deflection of electrons by magnetic fields and gamma rays. And won the Nobel Prize in 1903 (with the Curies).
-
J.J. Thomson discovered the electron. Used a cathode ray tube to experimentally determine the charge to mass ratio of an electron. Found that 'canal rays' were associated with the proton H+.

Werner Heisenberg developed the orbital theory of chemical bonding. Described atoms using a formula related to the frequencies of spectral lines. Stated the Uncertainity Principle (1927). And won the Nobel Prize in 1932.
