Before the 19th century ended, Bosch expanded his operations beyond Germany. The company established a sales office in the UK in 1898, and other European countries soon after. The first sales office and the first factory in the U.S. were opened in 1906 and 1910 respectively. By 1913, the company had branch operations in America, Asia, Africa, and Australia, and was generating 88% of its sales outside Germany. In rapid succession in the years following the First World War, Bosch launched innovations for the motor vehicle, including diesel fuel injection in 1927. In the 1920s the global economic crisis caused Bosch to begin a rigorous program of modernization and diversification in his company. In only a few years’ time, he succeeded in turning his company from a small automotive supplier into a multinational electronics group.
From the beginning, Bosch was greatly concerned about promoting occupational training. Prompted by his awareness of social responsibility, he was one of the first industrialists in Germany to introduce the eight-hour work day, followed by other social benefits for his associates. Robert Bosch did not wish to profit from the armaments contracts awarded to his company during WWI. Instead, he donated several million German marks to charitable causes. A hospital that he gave to the city of Stuttgart opened in 1940.
In the 1920s and 1930s, Robert Bosch was politically active. As a liberal businessman, he sat on a number of economic committees. He devoted a great deal of energy and money to the cause of bringing about reconciliation between Germany and France. He hoped this reconciliation would bring about lasting peace in Europe, and lead to the creation of a European economic area.
The Nazi (National Socialist) regime in Germany brought Bosch’s peacemaking efforts to an abrupt end. The company accepted armaments contracts, and employed forced laborers during the war. At the same time, Robert Bosch supported the resistance against Adolf Hitler: together with his closest associates, he saved victims of Nazi persecution from deportation.
Robert Bosch was keenly interested in agricultural issues, and owned a farm south of Munich. He was also a passionate hunter. When he died in 1942, he was survived by four children from two marriages. A son from his first marriage died in 1921 following a protracted illness.
In 1937, Robert Bosch had restructured his company as a private limited company (close corporation). He had established his last will and testament, in which he stipulated that the earnings of the company should be allocated to charitable causes. At the same time, his will sketched the outlines of the corporate constitution which was formulated by his successors in 1964 and is still valid today.
