Timeline of Nuclear Physics

The reader must understand that this is not a total outline of the development of physics but what I deem is the line of discoveries that leads directly to the development of atomic energy. As an example I offer thermodynamics. For this, I could develop a separate trail with some similar names such as Maxwell who besides work on electrodynamics did fundamental work on the kinetic energy of gasses. But in addition to Maxwell, that line would also include a large number of developments in the late 19th century, many with French names associated with them that do not appear here.
