Together with Wilhelm Hartwich, Willi Vietsch (1898–?) led the design firm and nursery Hartwich & Vietsch. The partnership, which was founded in 1927, was responsible for numerous garden designs in Vienna. Vietsch was himself an inhabitant of the Vienna Werkbund Estate (house no. 7 by Richard Bauer) and designed the gardens of house no. 62 by Margarete Schütte-Lihotzky and house no. 31 by Oskar Wlach. The partnership was dissolved in 1934 following Hartwich’s imprisonment as an illegal National Socialist. After the National Socialists took power, Vietsch received no further commissions and took his own life in 1944.
