His son Erwin Planck wis executit in 1945 bi the Gestapo for his part in the assassination attempt on Adolf Hitler Julie 20 plot.

Planck made mony contreibutions tae theoretical pheesics, but his fame as a pheesicist rests primarily on his role as the oreeginator o quantum theory, that revolutionised human unnerstaundin o atomic an subatomic processes. In 1948 the German scienteefic institution the Kaiser Wilhelm Society (o that Planck wis twice preses), wis renamed the Max Planck Society (MPS). The MPS nou includes 83 institutions representin a wide range o scienteefic directions.
