The First World War not only brought ruling dynasties and empires to an end, the 1920s also saw many changes in art, music, literature and architecture. While jazz, atonal music and expressionism failed to establish themselves in little Innsbruck, a handful of architects changed the cityscape in an astonishing way. Inspired by new forms of design such as the Bauhaus style, skyscrapers from the USA and the Soviet Modernism from the revolutionary USSR, sensational projects emerged in Innsbruck. The best-known representatives of the avant-garde who brought about this new way of designing public space in Tyrol were Lois Welzenbacher, Siegfried Mazagg, Theodor Prachensky and Clemens Holzmeister. Each of these architects had their own idiosyncrasies, making the Tiroler Moderne is difficult to define clearly. What they all had in common was a departure from the classicist architecture of the pre-war period. Lois Welzenbacher wrote in 1920 in an article in the magazine Tyrolean highlands about the architecture of this period:

"As far as we can judge today, it is clear that the 19th century lacked the strength to create its own distinct style. It is the age of stillness... Thus details were reproduced with historical accuracy, mostly without any particular meaning or purpose, and without a harmonious overall picture that would have arisen from factual or artistic necessity."

The best-known and most impressive representative of the so-called Tiroler Moderne was Franz Baumann (1892 - 1974). Unlike Holzmeister or Welzenbacher, he had no academic training. Baumann was born in Innsbruck in 1892, the son of a postal clerk. The theologian, publicist and war propagandist Anton Müllner, alias Bruder Willram became aware of Franz Baumann's talent as a draughtsman and enabled the young man to attend the Staatsgewerbeschule, today's HTL, at the age of 14. It was here that he met his future brother-in-law Theodor Prachensky. Together with Baumann's sister Maria, the two young men went on excursions in the area around Innsbruck to paint pictures of the mountains and nature. During his school years, he gained his first professional experience as a bricklayer at the construction company Huter & Söhne. In 1910 Baumann followed his friend Prachensky to Merano to work for the company Musch & Lun to work. At the time, Merano was Tyrol's most important tourist resort with international spa guests. Under the architect Adalbert Erlebach, he gained his first experience in the planning of large-scale projects such as hotels and cable cars.

Like the majority of his generation, the First World War tore Baumann from his professional and everyday life. On the Italian front, he was shot in the stomach while fighting, from which he recovered in a military hospital in Prague. During this otherwise idle time, he painted cityscapes of buildings in and around Prague. These pictures, which would later help him to visualise his plans, were presented in his only exhibition in 1919.

Baumann's breakthrough came in the second half of the 1920s. He was able to win the tenders for the remodelling of the Weinhaus Happ in the old town and the Nordkettenbahn railway. In addition to his creativity and ability to think holistically, he was also able to harmonise his architectural approach with the legal situation and the modern requirements of tendering in the 1920s. Construction was a state matter, the Tyrolean Heritage Protection Association together with the district administration, was the final authority responsible for the assessment and authorisation of construction projects. During his time in Merano, Baumann was already involved with the Homeland Security Association came into contact with it. Kunibert Zimmeter had founded this association together with Gotthard Graf Trapp in the final years of the monarchy. In "Our Tyrol. A heritage book" he wrote:

"Let us look at the flattening of our private lives, our amusements, at the centre of which, significantly, is the cinema, at the literary ephemera of our newspaper reading, at the hopeless and costly excesses of fashion in the field of women's clothing, let us take a look at our homes with the miserable factory furniture and all the dreadful products of our so-called gallantry goods industry, Things that thousands of people work to produce, creating worthless bric-a-brac in the process, or let us look at our apartment blocks and villas with their cement façades simulating palaces, countless superfluous towers and gables, our hotels with their pompous façades, what a waste of the people's wealth, what an abundance of tastelessness we must find there."

The economic boom of the late 1920s saw the emergence of a new clientele and clientele that placed new demands on buildings and therefore on the construction industry. In many Tyrolean villages, hotels had replaced churches as the largest building in the townscape. The aristocratic distance from the mountains had given way to a bourgeois enthusiasm for sport. This called for new solutions at new heights. No more grand hotels were built at 1500 m for spa holidays, but a complete infrastructure for skiers in high alpine terrain such as the Nordkette. The Tyrolean Heritage Protection Association ensured that nature and townscape were protected from overly fashionable trends, excessive tourism and ugly industrial buildings. Building projects had to blend harmoniously, attractively and appropriately into the environment. Despite the social and artistic innovations of the time, architects had to keep the typical regional character in mind. This was precisely the strength of Baumann's approach to holistic building in the Tyrolean sense. All technical functions and details, the embedding of the buildings in the landscape, taking into account the topography and sunlight, played a role for him, who was not officially allowed to use the title of architect. He thus followed the "Rules for those who build in the mountains" by the architect Adolf Loos from 1913:

Don't build picturesquely. Leave such effects to the walls, the mountains and the sun. The man who dresses picturesquely is not picturesque, but a buffoon. The farmer does not dress picturesquely. But he is...

Pay attention to the forms in which the farmer builds. For they are ancestral wisdom, congealed substance. But seek out the reason for the mould. If advances in technology have made it possible to improve the mould, then this improvement should always be used. The flail will be replaced by the threshing machine."

Baumann designed even the smallest details, from the exterior lighting to the furniture, and integrated them into his overall concept of the Tiroler Moderne in.

From 1927, Baumann worked independently in his studio in Schöpfstraße in Wilten. He repeatedly came into contact with his brother-in-law and employee of the building authority, Theodor Prachensky. From 1929, the two of them worked together to design the building for the new Hötting secondary school on Fürstenweg. Although boys and girls still had to be planned separately in the traditional way, the building was otherwise completely in keeping with the style of the Neuen Sachlichkeit and the principle Light, air and sun.

In his heyday, he employed 14 people in his office. Thanks to his modern approach, which combined function, aesthetics and economical construction, he survived the economic crisis well. Only the 1000-mark barrierwhich Hitler imposed on Austria in 1934 in order to put the Republic in financial difficulties, caused problems for his architectural practice and the economy as a whole. Not only did the unemployment rate in tourism triple within a very short space of time, but the construction industry also got into difficulties. In 1935, Baumann became head of the Central Association of Architects after he was finally allowed to use this professional title with a special licence. In the same year, he planned the Hörtnaglsiedlung in the west of the city.

After the Anschluss in 1938, he quickly joined the NSDAP. On the one hand, like his colleague Lois Welzenbacher, he was probably not averse to the ideas of National Socialism, but on the other he was able to further his career as chairman of the Reich Chamber of Fine Arts in Tyrol. In this position, he courageously opposed the destructive furore with which those in power wanted to change Innsbruck's cityscape, which did not correspond to his idea of urban planning. The mayor of Innsbruck, Egon Denz, wanted to remove the Triumphal Gate and St Anne's Column in order to make more room for traffic in Maria-Theresienstraße. The city centre was still a transit area from the Brenner Pass in the south to reach the main road to the east and west on today's Innrain. At the request of Gauleiter Franz Hofer, a statue of Adolf Hitler was to be erected in place of St Anne's Column. Hofer also wanted to have the church towers of the collegiate church blown up. Baumann's opinion on these plans was negative. When the matter made it to Albert Speer's desk, he agreed with him. From this point onwards, Baumann was no longer awarded any public projects by Gauleiter Hofer.

After being questioned as part of the denazification process, Baumann began working at the city building authority, probably on the recommendation of his brother-in-law Prachensky. Baumann was fully exonerated, among other things by a statement from the Abbot of Wilten, whose church towers he had saved, but his reputation as an architect could no longer be repaired. Moreover, his studio in Schöpfstraße had been destroyed by a bomb in 1944. In his post-war career, he was responsible for the renovation of buildings damaged by the war. Under his leadership, Boznerplatz with the Rudolfsbrunnen fountain was rebuilt as well as Burggraben and the new Stadtsäle (Note: today House of Music).

Franz Baumann died in 1974 and his paintings, sketches and drawings are highly sought-after and highly traded. Anyone who takes a close look at recent major projects such as the city library, the PEMA towers and many of Innsbruck's housing estates will recognise the approaches of the Tiroler Moderne rediscover even today.
