The company was founded by Dr. Hermann Schwarz and Dr. Lothar Rohde in Munich in 1933 after working together on a project in 1932. They met a few years earlier during their studies in Jena (Germany). In 1932 they built their first test instrument and in August 1933, they went in business together as Physikalisch-Technisches Entwicklungslabor Dr. Rohde & Dr. Schwarz, 1 which was often abbreviated to PTE [1]. In 1945 the name was changed to Rohde & Schwarz.
