Hugo Wach, born in Tübingen in 1872 and a grandson of the composer Felix Mendelssohn-Bartholdy, bought a house in Murnau in 1921 and spent almost 15 years renovating it with his imagination and incorporating various stylistic elements that he had come across on his travels. At the same time, he lived in Berlin, where he had held a professorship for architectural, freehand and ornamental drawing at the Technical University since 1920. This was revoked in 1935 due to his Jewish origins. In Murnau, he not only realized his dream of a croquet court and a Chinese pagoda with the house, which was originally built for the sculptor Max Schmitt, but also created an impressive work of art. Architectural styles from Africa, Asia and India were incorporated into the building, which still stands out from the Alpine architectural style of the surrounding houses today with its bay windows, turrets and a Chinese pagoda. His most important architectural project was the construction of the Agfa film factory with its own factory settlement in Wolfen in 1909. The sketchbook was found in 2022, together with a box full of documents, letters and photographs, built under the stairs of his former house. Hugo Wach had also planned a built-in chamber for himself in which he could have hidden in an emergency.
