Hermann von Siemens

During the final years of World War II, numerous plants and factories in Berlin and other major cities were destroyed by Allied air raids.

Arrested on 5 December 1945 by Allied Forces, he temporarily ceded the chairmanships to his father's first cousin Friedrich Carl Siemens (1877–1952).

He was brought to the Nuremberg trials as a prisoner to deal with war crime charges, but finally no prosecution was filed, as there were no personal misdeeds traceable.

In 1950, Hermann von Siemens donated his parents' sumptuous residence at Wannsee in Berlin to the Baptist Church which converted it to a hospital.

Hermann von Siemens significantly contributed to the company's reconstruction and development after World War II.

Himself rather a silent, introverted and technical-oriented person, he took special interest in all matters of scientific research and enhanced it in many ways.

In the 1950s and from their new base in Bavaria, S&H started to manufacture computers, semiconductor devices, washing machines, and pacemakers.
