Iosif Rosenbluth received his artistic education at the National School of Architecture and the Academy of Fine Arts in Bucharest, where he studied under Frederic Storck and G.D. Mirea, before continuing his training in Paris at the École des Beaux-Arts and the Académie Julian. His formation combined the architectural discipline of structure with the Parisian refinement of pictorial composition, producing a synthesis of rigorous construction and lyrical sensibility. He made his debut in 1926 at the Official Salon of Drawing and Engraving in Bucharest and subsequently participated in numerous exhibitions of painting and printmaking, attracting the attention of both critics and the public.

Rosenbluth’s practice reveals a sustained interest in landscape and the urban environment. His works display a lucid observation of Bucharest’s changing urban fabric, depicting parks, public gardens and notable monuments with a sense of calm precision that distances him from the nostalgic provincialism often associated with interwar city imagery. Rather than cultivating sentimentality, he explored the structural rhythms of the city and its atmosphere of quiet modernity. Alongside these urban compositions, his studio works — particularly still lifes and floral subjects — demonstrate a disciplined analysis of form, texture and material presence. His subdued palette and preference for dim light convey introspection, prioritising tonal harmony over the spectacle of light.
