Artist and lecturer, born in London, whose work was “influenced strongly by the British Neo-Romantics”. He worked in oil, watercolour, mixed media, acrylic and oil pastel. Rosenthal studied at Southend and Leicester Schools of Art. As a young artist he “had a pavement exhibition outside the Tate Gallery where the director, Sir John Rothenstein, gave me five shillings and sent out a cup of tea on a silver tray.” Rosenthal was “thrown out of various colleges for being naughty”, but was a visiting lecturer/artist-in-residence at the Graham Sutherland Gallery near where Rosenthal set up a studio gallery in Saint Davids, Pembrokeshire. Welsh landscapes, especially those of Pembrokeshire, were his main works, shown in mixed exhibitions in London, including the Ben Uri Gallery, and Leicester.
