The book "Kurt Mettler" offers a deep insight into the life of a young man whose brief existence was marked by intense experiences and inner conflicts. Mettler, from a wealthy textile trading family in St. Gallen, left behind a valuable written legacy, particularly his diaries, which capture his thoughts and experiences. These records reflect his travels to the world's metropolises and document his encounters with the art scene he discovered during his stay in the USA. Additionally, they address his struggle with his homosexuality and the challenges that came with it. Mettler's diaries are not only a personal document but also a testament to the tensions between tradition and modernity in his generation.
