Remo Saraceni, 89, Dies; Inventor of the Walking Piano Seen in ‘Big’

Remo Saraceni, a sculptor, toy inventor and technological fantasist best known for creating the Walking Piano that Tom Hanks and Robert Loggia danced on in a beloved scene of the hit 1988 movie “Big,” died on June 3 in Swarthmore, Pa. He was 89.

The cause was heart failure, said Benjamin Medaugh, his assistant and caretaker. Mr. Saraceni died at Mr. Medaugh’s home, where he had been living in recent years.

Mr. Saraceni’s specialty was “interactive electronics,” he told New York magazine in 1976. His other inventions included a clock that could reply aloud when you asked it the time, a stethoscope stereo system that could boom out your heartbeat, and Plexiglas clouds that lit up at the sound of a whistle with a pastel color appropriate for a room’s lighting. All were powered by what Mr. Saraceni (pronounced SAR-ah-SAY-nee) called “people energy”: the voice, touch and heat of the human body.

The power of this sort of technology to enchant its users became a pivotal plot element of “Big,” and in turn the central prop in one of the most fondly recalled scenes in recent movie history.

After wishing to be “big” at a magical Zoltar fortunetelling machine, the movie’s main character, Josh Baskin, transforms from a 12-year-old boy into a young adult (played by Mr. Hanks). He gets a clerical job at a toy company whose owner, Mac (Robert Loggia), recognizes Josh as his employee one Saturday at F.A.O. Schwarz. Mac is a shrewd capitalist surveying his industry in action; Josh is a boy exulting in the world of toys (albeit in a man’s body).

As Josh impresses Mac with his close knowledge of F.A.O. Schwarz’s wares, they happen upon Mr. Saraceni’s nearly 16-foot-long Walking Piano. With childlike absorption, Josh begins hopping on it to the tune of “Heart and Soul.” Mac, inspired by Josh’s un-self-conscious delight, joins him, making the performance a duet. To an awe-struck crowd, the two of them then do a rendition of “Chopsticks.”
