In Wiesbaden's south-east district, a street was named after the architect Hermann Jansen (1869-1945) by resolution of the city council on October 11, 1956. In the immediate vicinity of Hermann-Jansen-Straße, other traffic areas were dedicated to architects. For example, Balthasar-Neumann-Straße, dedicated to the most important Baroque architect, is located in the immediate vicinity.

Hermann Jansen was born in Aachen on May 28, 1869. After attending the humanistic Kaiser-Karls-Gymnasium in his native city, Jansen studied architecture and urban planning at the Rheinisch-Westfälische Technische Hochschule Aachen. Jansen then moved to Berlin and worked for a year for the city council of Berlin.

From 1898, Jansen worked as an independent architect. His work focused on the field of urban planning. In 1909, he won first prize for his general development plan for Greater Berlin. His ideas for a dense rapid transit network, generously laid out and intersection-free main roads, parks and large green spaces that would connect the city center with the open countryside were particularly innovative. He planned closed residential and settlement areas for workers and employees, shielded from the major traffic arteries, instead of parade grounds with monumental buildings.

Following this success, Jansen was entrusted with further urban development projects (for example in Dresden, Plauen, Leipzig and Emden). He also drew up a partial development plan for the Sonnenberg housing estate for the city of Wiesbaden. Jansen also drew up a traffic and area plan for the city, which was published in 1929 together with the development plan for Sonnenberg in the magazine "Der Städtebau", issue 24. In 1920, Jansen was appointed as an associate professor at the Technische Hochschule Berlin and in 1923 was made a full professor. Due to his outstanding work in the field of urban planning, Jansen received an honorary doctorate from the Technical University of Stuttgart in 1919.

His most important work was done in Turkey. In 1929, Jansen won a competition organized by the Turkish government for the development planning of the new capital Ankara. This was followed by further projects in Izmir, Adana, Tarsus and Mersin.

In 1930, he was appointed professor of urban planning at the University of Berlin. In 1939, he was awarded the Goethe Medal for Art and Science by Adolf Hitler. Hermann Jansen was a member of numerous associations and organizations, including being a full member of the Prussian Academy of Arts and the Academy of Architecture. The urban planner had been a member of the Reichskammer der bildenden Künste since 1941.

Hermann Jansen worked on urban planning with the Nazi regime, in particular with Albert Speer. As general building inspector for the Reich capital, Speer was responsible for redesigning Berlin in the National Socialist spirit. Speer's commissions to Jansen have survived, which prove that the urban planner was responsible for the design of the Gatow-Kladow and Selchow-Rotberg estates. Jansen received a fee of 15,000 RM for his design. Hermann Jansen died in Berlin shortly before the end of the Second World War on February 20, 1945.
