Secondo Campini (born August 28 1904 in Bologna, died February 7 1980 in Milan) was an Italian engineer and one of the pioneers of the jet engine. In 1931 Campini wrote a proposal for the Italian Air Ministry on the value of jet propulsion and in 1932 demonstrated a jet-powered boat in Venice. With support of the Air Ministry, he began work with Italian aircraft manufacturer Caproni to develop a jet plane, the Campini Caproni CC.2, which first flew in 1940. Wikipedia
