Elia Interguglielmi (1746 – 16 May 1835) was an Italian painter of the Neoclassical style, active in Naples and Palermo.
One of his descendants, likely grandson, is Eugenio Interguglielmi (19th century), who was a prominent photographer in Palermo.
In 1863, he opened a studio on largo Santa Sofia and corso Vittorio Emanuele.
Eugenio the younger (1876-1948) was also a photographer, with a studio on via Cavour n. 84, facing piazzetta Valenti.
Eugenio the younger's sister, Celestina (1880 - 1957) married the photographer Benedetto Bronzetti (1870 - 1944).
