Franz Hoffmann (architect, 1884)

from Wikipedia, the free encyclopedia
Franz Hoffmann around 1935

Franz Hoffmann (born June 13, 1884 in Charlottenburg ; † July 15, 1951 Berlin-Westend ) was a German architect whose main activity was in the Berlin area. From 1909 and 1912 until his death in 1951, Hoffmann was a partner of the brothers Bruno and Max Taut , but his work was always overshadowed by the more famous. Many of the buildings planned and implemented together have been preserved, 14 have been included as architectural monuments in the Berlin State Monument List .

Life

Family and education

Franz Hoffmann was the son of the master builder and carpenter Friedrich Hoffmann, whose parents came from Lausitz . The mother, Marie Rudlof, came from an arable family in Nauen . The father owned many houses in Berlin-Schöneberg and was very wealthy. Franz had two older sisters - Elsbeth, who later worked as an accountant in his office, and Anna, who married the son of the laundry owner Erwin Reibedanz around 1910 .

Franz attended the community school until 1895, after which he switched to the 6th Higher Citizens School, which he successfully completed in the summer of 1902. He then completed a school education up to secondary school in Bad Sachsa . In 1905 Hoffmann finally acquired a journeyman's certificate as a carpenter at the Berlin building trade school . He broke off a subsequent study of architecture at the Technical University of Charlottenburg in 1907, completed a second apprenticeship as a bricklayer and passed an examination as a master builder.

Service as a one-year volunteer and foundation of the Taut & Hoffmann office

After completing his basic technical training, Franz Hoffmann began his service as a one-year volunteer with the Uhlans in Salzwedel . Back in his hometown Schöneberg , Hoffmann got a job in Heinz Lassen's architecture office . Here he worked until July 1909, met Bruno Taut while working together and they decided to set up their own office. Until the business license was granted on August 9, 1909 for the Taut & Hoffmann architects' association , both of them gained their first own experience in and outside of Berlin as independent construction specialists. As start-up capital for the new “master builder community”, Franz received an amount of 5,000 marks from his grandmother . They rented a small office at Linkstrasse 20 (later Potsdamer Strasse 119) near Potsdamer Platz in Berlin-Mitte.

After minor tasks and numerous participation in competitions, they received two important commissions in 1910: They won the competitions for the construction of workers' housing estates in Magdeburg ( Garden City Colony Reform ) and in Falkenberg near Grünau . - During the implementation of these projects, Hoffmann clearly recognized the responsibility of building owners and architects for future apartment users and formulated his credo in later years:

“Since 1910, I have been working very closely with Professor Bruno Taut and later also with Professor Max Taut on building workers' apartments. [...] For the economically weak population, this social housing means building on the basis of the cost calculation, renouncing any profit with strict rent calculation. [...] It will be ensured that the apartments have good floor plans and are solidly built. Bad housing and bad building without quality not only spoil the character, but are extremely questionable for purely economic considerations and inhibit the healthy development of the nation as a whole. "

The now established office community Taut & Hoffmann joined in 1912 (according to another source 1913) Max Taut , the younger brother of Bruno Taut. Franz Hoffmann became a member of the SPD in 1912, probably due to his experience in building workers' housing and the numerous conversations he had with future residents . The socialist ideas of this party represented at the time came closest to his ideas of a better society.

The large residential complexes, which became known through the media, led to numerous other building projects by private individuals, building associations and municipal institutions in Charlottenburg and the later neighboring districts of Berlin. Until the beginning of the First World War , Franz Hoffmann was able to hire more and more talented civil engineers. He and his partners preferred building trade school graduates to academics.

From the First World War to the end of the Weimar Republic

In 1914 there was an interruption in Hoffmann's professional career, he had to start his military service on October 14th . As a cavalryman he was used on the German Eastern Front. After the end of the war, he returned from the mission on February 1, 1919. His office partners had meanwhile continued to work and their good reputation always brought them new jobs. So Franz Hoffmann was able to work as an architect again together with them.

On June 5, 1924 Hoffmann married the singer Charlotte ("Lotte") Hennig, they raised their daughter Sigrid ("Isi"; married Fischer-Sperling) together. Through the marriage, Hoffmann got in touch with the Quaker organization , resigned from the Protestant Church and became a member of the Quakers. He remained associated with this aid organization for a lifetime. In 1932, for example, he had made a name for himself in the implementation of the administration building - the so-called Quaker House  . In the special cemetery for the deceased members of this organization in Bad Pyrmont , a memorial plaque for Franz Hoffmann was also placed after his death. In the Eichkamp estate , which Taut & Hoffmann were heavily involved in during this period, Franz Hoffmann also built a house for his family (Zikadenweg 70). He had the interior of his half equipped with the most modern materials of the time and with well thought-out amenities, such as built-in cupboards, a glazed veranda, a wall cupboard that can be used on both sides instead of a partition between the kitchen and living room or a cork floor. Radio stations were not yet that widespread, which is why the Hoffmanns often made music together at home.

According to his wife, Franz Hoffmann was “an acquirer, managing director and above all confidante for the Taut brothers; certainly less creative, but certainly stimulant, critic and always involved in the assessment. ”The daughter, who for a few years was closely associated with the work of Franz Hoffmann, gave the following assessment in 1995:“ My father was not a creative artist. As a person, he was an analyst who, through his innate intuition, was able to recognize artistic and functional achievements with absolute certainty. [...] He also had a very warm way of approaching everyone he met. Bruno Taut seemed to appreciate these qualities in him when he formed an 'architects' association' with him in 1909. It was undoubtedly not the money my father had inherited that led Bruno to make this merger. That wouldn't suit Bruno. Back then, this talented young architect, Bruno Taut, would have found other partners as well. Otherwise why should he have continued the partnership after the First World War, when he slowly worked his way up to great financial successes. [...] Above all, my father was always the last person to correct floor plans, floor plans were his strength. "

From 1930 until the end of World War II

In a publication of the 8 o'clock evening paper in the 1930s, under the heading “Berlin will still be the ugliest city in the world”, a very derogatory criticism of the special workers' housing by Hoffmann and Taut was expressed: “Berlin's tradition is not artistic, but rather it is the tradition of work. […] Let's not refer to Schinkel , who said 'architecture is nothing if it is not new', than to Hoffmann, who says 'architecture is nothing if it is not old'. ”The architects had meanwhile Especially in Charlottenburg, which had meanwhile been incorporated into Berlin, a large number of rental houses were converted, based on their ideas of healthier living.

Independent of the planning and construction activities of the trio of architects, Franz Hoffmann and the building contractor Georg Schuster developed the new building material cork cement and the corresponding manufacturing process. In 1936 they registered a patent for it as a “building material containing cork and cement and a process for its production” . The patent was granted in 1939 and was classified as DRP 675 177 (Class 80b, Group 2104). In 1937, both of them submitted a component based on the new building material as a utility model patent: "Combined building panels", which was also granted to them (DRGM 1378 987). The patents were registered in Germany, Great Britain, France, Italy, Belgium, Luxembourg, Portugal as well as Morocco, Canada, Egypt and Palestine and were probably also commercially exploited (the documents do not provide any clear information about this).

The business premises in Potsdamer Strasse used by the architects' society were given up in 1932 because of the original 37 employees (1929, for the twentieth anniversary), several had to be laid off gradually. The global economic crisis led to a decline in orders, but also to serious financial problems, because already finished buildings were no longer paid for. They moved into rooms in an office building they had previously built at Bayreuther Strasse 27–28. But a short time later, during the National Socialist era , more employees had to stop because the architects refused to build for the new rulers. Now there were only orders from private individuals or from trade union organizations. Bruno Taut worked in the Soviet Union from 1932 to 1933 and then emigrated via Japan to Turkey because there were difficulties with the required “ Aryan certificate ”. The poor order situation also had a personal impact. The Hoffmann family rented out individual rooms in their house and had to give notice to the housekeeper.

Franz Hoffmann and his wife were active members of the Quakers, as explained above. From 1933 onwards, the Berlin Quaker Office maintained an advice center for Jews and other victims of the Nazi regime in what was then Prinz-Louis-Ferdinand-Strasse (today Planckstrasse), where Frau Hoffmann worked. This humanitarian aid continued during the war. In addition, the group decided to collect school books in German, English or Russian and send them to prisoner-of-war camps after reviewing them, because they had learned that German prisoners of war were being looked after by British and American Quakers. Franz Hoffmann carried out the book collection in the educational institutions with the permission of the SS security service . For his legitimation he received a letter of approval with the official ( swastika ) seal, which he always carried with him.

The office building was so badly damaged by a fire bomb on November 23, 1943 that it was no longer possible to work here. An application made by Hoffmann in October 1944 for “financial compensation according to the 1940 War Damage Ordinance” with a corresponding list shows a loss of around 70,000 Reichsmarks. What, when and in what amount was paid cannot be found out. Hoffmann had found a new task for himself and his few employees that saved them from being deployed in the war: the city of Berlin distributed individual residential areas to architectural offices for the structural supervision of repairs after air raids, resulting in "Aircraft Damage Removal Offices" (FSBB). Hoffmann received the core area between Wittenbergplatz , Olivaer Platz and Steinplatz with the Kaiser Wilhelm Memorial Church in the center from the Charlottenburg District Office . With two former employees (M. Schultz and site manager Erich Voss) they moved into commercial space in a former clothing store on Kurfürstendamm in 1942 . (Max Taut's house was also destroyed by a bomb, so that he moved to Chorin around 1943 , from where he did not get to work in Berlin.) The FSBB was now under the direction of Hoffmann, who was responsible for assessing war damage and arranging repairs and had to coordinate compulsory craftsmen.

New start with problems

When the Red Army reached Berlin and a Soviet headquarters was established in Eichkamp at the end of April 1945, Franz Hoffmann came under control. The letter from the security service regarding the book collection was found on him with the imprint of a swastika and the SS mark. Because none of the soldiers or officers here could speak German, they took Hoffmann for a supporter of the National Socialists and took him prisoner. He was taken to a collection center in the Grunewald area and probably suffered severe abuse there. Only after a week was an interpreter able to clear up the mistake and Franz Hoffmann was released. He had changed so much that at first even his wife didn't recognize him. He never told anyone about the details of this period.

The architecture office did not officially exist between July 1945 and August 1946, Max Taut and Franz Hoffmann applied for a new business license as the architecture office Taut & Hoffmann (Bruno Taut had died in Turkey in 1938), which was granted to them on May 8, 1946 by the Charlottenburg district office . Above all, Franz Hoffmann now conducted extensive correspondence with previous customers, including high-ranking people in other (federal) states such as North Rhine-Westphalia , in order to get new orders. In addition, they worked on repairs to damaged houses, mainly due to the enormous war damage. However, new project orders could not be obtained because both materials and funds were missing. Publications about her realized buildings and specialist lectures - for example in 1950 "About social building and about workers' settlements in the past and future" by Franz Hoffmann - brought some income. When Max Taut increasingly tried to get his own construction contracts around 1950, the long-standing community broke up.

Franz Hoffmann was a member of the Association of German Architects .
