Hans Joachim Dominik, undated

The engineer and scientist Hans Dominik joined the "Department of Lighting and Power" at Siemens & Halske in 1900. Following a comprehensive project on electrification in mining for the Paris World Exhibition, he was made manager of the Literary Department (public relations), a post he held for around a year. From 1917 Dominik worked as an engineer in the area of telegraphy. He was also a writer, and from 1922 published a series of technological utopian novels. The most important works of this author, who was also hailed as the "German Jules Verne", include the novels "Die Macht der Drei" (1922), "Die Spur des Dschingis-Khan" (1923), "Der Brand der Cheopspyramide" (1926), "Befehl aus dem Dunkel" (1933), "Der Wettflug der Nationen" (1934), "Atomgewicht 500" (1935), "Himmelskraft" (1937), "Treibstoff SR" (1940) and his memoires "Vom Schraubstock zum Schreibtisch" (1942).

Hans Domizlaff, in Spain 1930

After studying painting, Hans Domizlaff was initially involved in the visual and performing arts before he produced his first work as a commercial artist in 1920. He subsequently became an advertising consultant for various firms, which from 1933 also included Siemens. Two years later he was appointed head of the newly established Hauptwerbeabteilung at Siemens (HWA, Main Advertising Department). Domizlaff developed a new, uniform corporate style for Siemens based on the principle that the successful advertising of a brand name is based on establishing the brand as a symbol of justified confidence in genuine achievement. For Siemens he created the Rapid vacuum cleaner brand, the "Kammermusikgerät" (a tube radio) and a type of button telephone and for Deutsche Grammophon the word and picture logo. In 1954 he founded the Institute for Brand Technique in Hamburg, which existed until his death in 1971.

Hans Hertlein, 1927

Hans Hertlein joined the Building Department of the Siemens Werke in 1912 and succeeded Karl Janisch as its director in 1915. Initially he continued to work along the lsame lines as Janisch, but at the end of the 1920s developed his own characteristic building style. Under Hertlein (until 1951), industrial buildings and other constructions of a high architectural and artistic standard were created that were highly praised both in Germany and abroad, including, in Berlin-Siemensstadt, the Wernerwerk M with its tower, the Blockwerk II, the high-rise building of the Schaltwerk, the residential estate on the Rohrdamm, the Protestant and Catholic church and the VDE administrative building in the Bismarckstraße. In 1931 the Technical College of Hanover awarded Hertlein an honorary doctorate (Dr.-Ing. E.h.), and in 1946 he became a full professor at the Technical University of Berlin.

Karl Janisch, undated

After working in the elevated and underground railway department of Siemens & Halske, the government architect Karl Janisch took over as director of the Siemens Building Department in 1902. Until 1914 Janisch had a major role in the building of the Berlin district of Siemensstadt, where he was responsible for both the architecture and the urban development aspect. The design of this district with its industrial and residential buildings, communal and social facilities, was his life's work, for which he was awarded the title "Royal Architect" in 1913. In addition, at the request of Wilhelm von Siemens in 1910, Janisch constructed the Siemens-Schuckert Airship Hall in Biesdorf near Berlin, which could be rotated around its own axis, making the airship easier to bring in and protecting it from damage.
