Perhaps best known for his part in the engineering and development of the Steadicam, Di Giulio was active on various Academy subcommittees for many years and chaired the Academy's Scientific and Technical Awards Committee for five years. While at Mitchell Camera Corporation in the early sixties, he developed the company's first reflex camera - the Mark II - and in 1968, he received the Scientific and Engineering Award for the important design and application of a conversion that made it possible to change over most of the industry's existing sound cameras to reflex viewing. In 1992, he received another Scientific and Engineering Award for the camera system design of the CP-65 Showscan Camera System for 65mm motion picture cinematography. In 1998, Di Giulio received a Technical Achievement Award for the design of the KeyKode Sync Reader. The next year, Di Giulio received the John A. Bonner Medal of Commendation, awarded for "outstanding service and dedication in upholding the high standards of the Academy." Di Giulio authored a number of influential scientific papers and was a well-known lecturer who appeared at technical conferences and symposia both in the United States and around the world. An Academy member since 1966, Di Giulio was also fellow of the Society of Motion Picture and Television Engineers (SMPTE), and held more than a dozen patents in computer and cinema technology.  Scientific or Technical Awards (Class II) 1968: For the design and application of a convention which makes available the reflex viewing system for motion picture cameras.
