Otto Ludwig Haas-Heye (16 December 1879 – 9 June 1959) was a German fashion designer, professor at the Unterrichtsanstalt des Kunstgewerbemuseums Berlin [de] and owner of the publishing company Graphik-Verlag.
Otto Ludwig Haas-Heye was born in Heidelberg on 16 December 1879 to Prof. Hermann Haas (1852–1902)[a] and Hermanna Helene Heye (1857–1942).
After a year of volunteering at the Schwere Reiter Regiment in Munich, Haas-Heye continued this artistic training at the Académie Julian in 1901–1902.
He moved to Munich that same year, to Rome in 1904, to Paris in 1905 and then continued to travel through Turkey, Egypt, Greece and Albania in 1906.
Through hand-colored prints by Annie Offterdinger (1894–1987) published by Graphik-Verlag, Haas-Heye made his designs accessible to the public.
The ladies of the aristocracy, who still held the necessary financial resources, as well as celebrities, now turned to Berlin fashion houses like Gerson, Manheimer, and Alfred-Marie.
Haas-Heye was conscripted in April 1916, but was allowed to leave in August, probably due to his father-in-law's relations, through which he could have an audience with Helmuth von Moltke the Younger, Chief of the German General Staff.
Later that year, he assisted Hermann Muthesius in setting up the Deutscher Werkbund exhibition in Basel, where he organized a large fashion show, held in 1917 on a self-made stage.
In 1920, Bruno Paul appointed Haas-Heye as teacher at the Unterrichtsanstalt des Kunstgewerbemuseums Berlin [de], where he founded and the fashion and costume classes, subsequently receiving the title of professor in 1921.
