Today is the birthday (1861) of Robert Bosch, a German industrialist, engineer and inventor, founder of Robert Bosch GmbH, whose most famous invention, the spark plug, revolutionized the internal combustion engine. He was also a vocal advocate for humane industrial working conditions, and social conditions in general.

Bosch was born in Albeck, a village to the northeast of Ulm in southern Germany. He was the 11th of 12 children. His parents came from a class of well-to-do farmers from the region. His father, well-educated man, placed special importance on a good education for his children. As a child, Robert liked to try to invent. He tinkered with little electric or mechanical toys hoping to improve them or make something different out of them.

From 1869 to 1876, Bosch attended the Realschule (secondary-technical school) in Ulm, and then took an apprenticeship as a precision mechanic. After his school and practical education, Bosch spent a further 7 years working at diverse companies in Germany, the United States (for Thomas Edison in New York), and the UK (for the German firm Siemens). On 15th November 1886, he opened his own “Workshop for Precision Mechanics and Electrical Engineering” in Stuttgart. A year later, he made a decisive improvement to an unpatented magneto ignition device made by the engine manufacturer Deutz, providing his first business success. The purpose of the device was to generate an electric spark to ignite the air–fuel mixture in a stationary engine. In 1897, Bosch was the first to adapt a magneto to a vehicle engine. In doing so, he solved one of the greatest technical problems faced by the nascent automotive industry. The invention of the first commercially viable high-voltage spark plug as part of a magneto-based ignition system by Robert Bosch’s engineer Gottlob Honold in 1902 was a key stage in the development of the internal combustion engine.

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 North 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. 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 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, Bosch supported the resistance against Adolf Hitler and together with his closest associates saved victims of Nazi persecution from deportation.

In 1937, 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.

Bosch was granted a state funeral by the Third Reich when he died in 1942. He was inducted into the Automotive Hall of Fame in 1984.

Bosch came from an area of Germany where Swabian cuisine dominates, and tripe is popular in a region where meat was expensive. So, once again, I get to indulge my tripe fetish – this time with veal tripe, which you might find hard to get. Ox tripe will also work. If you are faint hearted, you can substitute chicken. The key to the dish is Trollinger, a red wine from the region.

Schwäbische Kalbskutteln (Swabian Veal Tripe):


1 kg cooked veal tripe, cut in strips
300 ml meat stock
60 ml sherry vinegar
50 gm flour
2 tbsp tomato paste
1 bottle Trollinger wine
1 onion, peeled and diced small
chopped fresh parsley
cooking oil


Sauté the onion in a little oil until transparent, add the sliced tripe and fry for a few minutes without letting it brown. Add the tomato paste, dust with flour and brown to make a dark roux. Stir in the Trolling and the meat stock. Simmer for around 30 minutes and season to taste with the sherry vinegar, salt and pepper.

Sprinkle with parsley and serve with fried potatoes.
