Max Karl Ernst Ludwig Planck was a German physicist who discovered quantum physics. He was the founder of quantum theory, for which he received  the  Nobel  Prize  in  Physics in 1918. Planck’s life was dotted with tragic occurrences. His first wife died  early.  His  younger  son  died  in World War I. He had twin daughters, one of which died during childbirth. The other twin married the husband of the first twin sister. They married and after two years she also died during childbirth. In 1944, when Planck was eighty-five, during World War II, a bomb fell on his house destroying all his documents and a lifetime of accumulations. The next year, his only surviving son was executed after being caught in a conspiracy to assassinate Hitler.
