Little is known of Rose Baron's background and career, other than that she was of Jewish origin, may have been self-taught, and lived and worked in Mile End in the East End of London, often painting scenes set in and around her home neighbourhood between the 1930s and 1950s. She showed three oils 'of Jewish interest' at the East End Academy exhibition at the Whitechapel Art Gallery in 1933 (as noted by the 'Jewish Chronicle'). She exhibited with Ben Uri regularly in 1935, 1936, 1937, 1944, 1945, 1948 (as Rosa Baron), 1949 and 1952 and was a member of the Ben Uri Arts Society in 1948. Her oil entitled Refugees, first exhibited in the East End Academy exhibition in 1934 and commended in the 'Jewish Chronicle', was subsequently displayed in the second Annual Exhibition of Works by Jewish Artists, hosted by Ben Uri at Woburn House in London WC1 in 1935. She donated her oil painting, 'Character in Petticoat Lane' (also later known as 'The Chicken Plucker') to the Ben Uri Collection in 1937, after it was shown in an exhibition at Ben Uri Gallery in May-June the same year. This archetypal genre scene could equally be set in the Jewish shtetl (a small town or village in Eastern Europe), or relocated to London's contemporaneous East End; her 'Onion Woman' - presumably another character study - was shown in an exhibition of contemporary portraits at Ben Uri Gallery in 1945.
