An Italian artist. He was closely associated with the Italian firm of Raoul Bigazzi.

Thanks to blogger jusdeananas, this excerpt from the Singapore Free Press, on Bigazzi's work on Crosby House:

"The supply and installation of all marble in Crosby House was entrusted to the well-known firm of artistic works, Raoul Bigazzi, whose Far East headquarters are in Hong Kong. The firm of Raoul Bigazzi has specialised in marbles, bronze, mosaics, and other branches of architectural decoration for the past 34 years. It has contributed to some 74 banking premises and many Marajahs [sic] and residences of royalty, some of which are scattered all over the world, but mostly in the Far East, from Peking to Bombay.In Singapore its pre-war work included Eu Villa, the Municipal Building, Supreme Court, Hong Kong Bank, Meyer Chambers, and Union Insurance Building.
The latest post war works have been the Bank of China, Finlayson House, Odeon Cinema and the Lim Bo Seng Memorial. The marble finishing of Crosby House, both in the materials chosen by the architects and the way they have been employed, is outstanding and well suited to this latest addition to the Singapore skyline.
