Isidoro Raponi was an Italian-born special effects creator.

Raponi helped design, build and operate E.T. for the 1982 Steven Spielberg classic and worked on such other films as King Kong, Alien and Close Encounters of the Third Kind.

Raponi also created the various dinosaurs seen in Disney's Baby: Secret of the Lost Legend. The creatures in that film ranged from the title youngster (a human performer inside a rubber costume used a remote control to execute its expressions and movements) to a mechanically operated Brontosaurus that stood 70 feet long and 25 feet wide.

Raponi died May 27, 2022 in Los Angeles, California. He was 76.
