Pietro Grossi (15 April 1917, in Venice – 21 February 2002, in Florence) was an Italian composer pioneer of computer music, visual artist and hacker ahead of his time.

In 1970 he made his first approaches to musical telematics organizing a performance with a link between Rimini (Pio Manzù Foundation) and Pisa (CNUCE).

By invitation of lannis Xenakis, he presented another telematic concert between Pisa and Paris in 1974.His contributions to the development of new technological musical instruments and to the creation of software packages for music-processing design have been fundamental with the original TAUmus/TAU2 station.

The last step of his HomeArt, is the creation of a series of unicum books, electronically produced and symbolically called HomeBooks (1991): each work is completely different from the others, thanks to the strong flexibility of the digital means.

He collaborated in order to experiment with electronic sound and composition with the computer music division of "CNUCE" (Institute of the National Research Council of Pisa).
