In 1896, he became an associate of the Royal Academy, with full membership following in 1906, one of the few Jewish painters to do so. He joined, and became president of, the Royal Society of British Artists in 1919.
Solomon illustrated for The Temple (G.A. Henty, 1887) and contributed works for Black and White (1891); The Graphic (1897-1904).
