The caesura of the First World War not only changed Innsbruck economically and socially, but also gave the city a new appearance. The visual arts reinvented themselves after the horrors of war. The classicism of the turn of the century was the architecture of a bourgeoisie that had tried to imitate the nobility. After the war, many citizens blamed this aristocracy for the horrors on the battlefields of Europe. Even before the war, sport and the phenomenon of leisure had become the expression of a new bourgeois self-image in contrast to the old order determined by the aristocracy. From now on, buildings and infrastructure were to serve every citizen equally. Aristocratic virtues and interest in classical antiquity had lost their lustre within a very short space of time.

The architects of the post-war period wanted to distinguish themselves from previous generations in terms of appearance, while at the same time maximising the functionality of the buildings. The end of the monarchy is reflected in the simplicity of the architecture. Lois Welzenbacher wrote about the architectural aberrations of this period in an article in the magazine Tiroler Hochland in 1920:

"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."

New forms of design such as the Bauhaus style from Weimar, high-rise buildings from the USA and Soviet Modernism from the revolutionary USSR found their way into design, construction and craftsmanship. The best-known Tyrolean representatives of this new way of designing public spaces were Siegfried Mazagg, Theodor Prachensky, Clemens Holzmeister and Lois Welzenbacher. Each of these architects had their own specialities, making it difficult to clearly define Tyrolean Modernism. Buildings such as the Innsbruck power station in Salurnerstrasse or the Adambräu near the railway station were striking buildings, not only of unprecedented height, but also in a completely new style. Despite all the enthusiasm for the dawn of new times, there was also a current of thought that is problematic for those of us born later. Filippo Tommaso Marinetti's Futurism not only exerted a great attraction on Italian fascism, but also on many representatives of modernist art and architecture.

The best-known and most impressive representative of the so-called Tiroler Moderne was Franz Baumann (1892 - 1974). Baumann was born in Innsbruck in 1892, the son of a postal clerk. The theologian, publicist and war propagandist Anton Müllner, alias Brother Willram, became aware of Franz Baumann's talent as a draughtsman and at the age of 14 enabled the young man to attend the Staatsgewerbeschule, today's HTL. 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, which was responsible for major projects in Innsbruck such as the Monastery of Perpetual Adoration and the Church of St Nicholas. In 1910, Baumann followed his friend Prachensky to Merano to work for the company Musch & Lun. At the time, Merano was Tyrol's most important tourist resort with international spa guests. The predominant styles were Art Nouveau and Historicism. 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.

After returning home from the war, Baumann worked at Grissemann & Walch and completed his professional qualification. Unlike Holzmeister or Welzenbacher, he had no academic training. In his spare time, he regularly took part in public tenders for public projects.

His big breakthrough came in the second half of the 1920s. Baumann 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 approach with the legal situation and the requirements of the tenders of the 1920s. According to the federal constitution of the Republic of Austria, construction was a state matter. Since the previous year, the Tyrolean Heritage Protection Association Together with the district authority, it was the final authority responsible for the assessment and approval of construction projects. Kunibert Zimmeter had already founded the association in 1908 together with Gotthard Graf Trapp. Zimmeter wrote in his book "Our Tyrol. A heritage book":

"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."

Nature and townscape should be protected from overly fashionable trends, excessive tourism and ugly industrial buildings. Building projects were to be integrated harmoniously, attractively and appropriately into the environment. Despite the social and artistic innovations of the time, architects had to bear in mind the typical character of the region.

After the First World War, a new class of customers and guests emerged 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. Mountain villages such as Igls, Seefeld and St. Anton were completely remodelled by tourism, and in Innsbruck a new district was created with the Hungerburg. 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. During his time in Merano, Baumann had already come into contact with the local heritage organisation. This is precisely where the strengths of his approach to holistic construction in the Tyrolean sense lay. 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 were still to be planned separately in the traditional way, the building was otherwise completely in keeping with the New Objectivity style in terms of form and furnishings, based on the principle of light, air and sun. In 1935 he managed the project Hörtnaglsiedlung in the west of the city.

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. The 1,000-mark freeze that Hitler imposed on Austria in 1934 in order to put the Republic in financial difficulties heralded the slow decline of his architectural practice. Not only did the unemployment rate in tourism triple within a very short space of time, but the construction industry also ran into difficulties.

In 1935, Baumann became the shooting star of the Tyrolean architecture scene and was appointed head of the Central Association of Architects after he was finally allowed to use this professional title with a special licence. After the Anschluss in 1938, he quickly joined the NSDAP. On the one hand, 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 as a German herald 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, 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. The diverse public and private buildings and projects of the ever-smoking architect still characterise Innsbruck today.
