Painter, member of the Group of Seven.
Rozental was born in Łódź, where he attended Jerzy Leman's drawing school and a philological high school. In 1915, he began his studies at the School of Fine Arts in Warsaw, from where, after only a year, he moved to Vienna, where he studied at the Academy of Fine Arts and the School of Artistic Crafts. In 1919–1920, he served in the Polish army and fought in the Polish-Soviet War.

Rozental began his artistic career in Łódź and the Start artistic group, which he co-founded. He was a member of the Association of Artists and Supporters of Fine Arts in Łódź. He also held several solo exhibitions in his hometown. However, he was not only involved in painting but also in theatre directing (he was one of the directors of the Łódź Theatre Studio) and music.
After marrying the renowned pianist Stefania Feltens, he moved to Warsaw. In the capital, he became involved with the Warsaw Group of Seven; he served as secretary of the Association of Jewish Visual Artists in Poland and taught drawing classes in the studio there. From 1929 to 1933, he lived in France, participating, among other things, in the exhibition of Polish painting in Nice (1932). Rozental's work was dominated by landscapes, primarily in watercolor, as well as still lifes and portraits with Post-Impressionist features.
During the war, he was in the Warsaw Ghetto, where in May 1942, to commemorate the twentieth anniversary of his artistic activity, an exhibition of his works was organized at 6 Orla Street. He worked in Abraham Ostrzega's whetstone factory and, like almost all its employees, perished, probably in the Treblinka extermination camp.
