David Howard Maude-Roxby-Montalto di Fragnito

David Montalto is married to Patricia Gail (née Lyons). They have two children Daniel James Francesco, Pincipe di Lequile (1974-2020) and Alexandra Rachel Jane (1976). David Montalto works and lives between his studios in Switzerland, Italy and England.

Montalto remained in Italy after his adoption and was offered a partnership with Giancarlo 'Jinx' Girard at Tunsi Ceramics. Some of their works have been acquired by The Museum of Childhood in Santa Fe, New Mexico, USA. Inspired by the works of Lawrence Whistler and other masters of diamond point stipple glass engraving, Montalto developed his own techniques. In 1973, to celebrate Great Britain joining the European Economic Community, David was commissioned to design and engrave series commemorative glasses which were presented to every Head of State. He has worked for the jewellers Harry Winston, designing and making an ornamental gold pendent to hold a 50 Carat Ruby. David has also designed a pen with a solid Baccarat Crystal box for Montegrappa, the luxury pen company. In 2008 David collaborated with the master watch maker Michel Parmigiani to create for Parmigiani Fleurier a uniquely engraved wrist watch.

In 1947, David traveled with his tutor (and one of his brothers) to Victoria, Australia to write and illustrate a book on the wildlife of the Great Barrier Reef. In Australia, he attended Geelong Grammar School, where he studied under Ludwig Hirschfeld Mack, a member of The Bauhaus movement. He returned to England, to attend Claysmore School in Dorse. After graduation, he went on to study at Sorbonne University and then the Accademia di Belle Arti in Florence Italy, studying under Primo Conti and Goffredo Trovarelli.

David Howard Maude-Roxby-Montalto di Fragnito (born 30 August 1934), also known as David Montalto, 14th Duke of Fragnito is a Swiss-based British artist craftsman, specializing in diamond-point stipple engraving, glass sculpture, painting and jewelry. Montalto has exhibited extensively in Britain, Europe and the United States, including regular exhibitions in London, Geneva and Paris. Some of his works are on permanent show at the Victoria and Albert Museum in London, Philadelphia History Museum at the Atwater Kent in Philadelphia, the Corning Museum of Glass in New York, as well as royal and international private collections in Great Britain, Brunei, Oman and more.

David was born in Curry Rivel, Somerset, England, to Howard James Trevelyan (1883 - 1971) and Joyce Maud Maude-Roxby (1899 - 1992). He was the fourth of five children. In 1966, he was adopted by his Italian cousins, Francesco Luigi Antonio Montalto, Duke of Fragnito (1899 - 1979) and Anna Maria Gabriella Giulia Cecilia Fioravanti (1909 - 1982) after they lost their son, Ruggiero Montalto di Fragnito Principe di Lequile who died in an accident in 1966. With the adoption, David M-R inherited his adopted parents' surname, Montalto di Fragnito, and their hereditary Italian noble titles (including upon the death of his adopted father), The Duke of Fragnito, Prince of Lequile). As his natural parents were still alive, he also kept their surname, Maude-Roxby.
