From 1892 to 1895, he was a pupil at the
Brera Academy in Milan, studying painting under
Cesare Tallone, sculpture and engraving under
Ernesto Bazzaro, and perspective under
Giuseppe Mentessi. In 1895–1900, he dedicated himself to
illuminated manuscripts. After the
First World War, he began exhibiting his landscapes at group shows in Milan and Genoa, participating in exhibitions of the Promotrici, at Brera, and at the Famiglia Artistica Milanese.
Leonardo Bazzaro influenced his choice of landscape and vedute. Rather than sunlit pastoral views, he preferred to depict the humid panoramas of the canals of Milan and the Venetian lagoons, and was particularly known for his views of old Milan blanketed in snow. In his final years, Solenghi retired to
Cernobbio, where he died on 8 March 1944. A posthumous retrospective exhibition was held in 1947 at the Galleria Boito in Milan, sponsored by the
Fondazione Cariplo. ==Notable exhibited works==
