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. He began experimenting with electronic techniques in Italy in the early sixties.

Pietro Grossi was born in Venice, and he studied in Bologna eventually taking a diploma in composition and violoncello. In the sixties Grossi taught at the Conservatorio Luigi Cherubini and began to research and experiment with electroacoustic music. From 1936 to 1966 was the first cellist of the Maggio Musicale Fiorentino orchestra. Grossi began to experiment with electroacoustic music in the 1950s. By 1962, he had become the first Italian to carry out successful research in the field of computer music.
In 1963, he turned his interest to electronic music and founded the S 2F M (Studio di Fonologia Musicale di Firenze) which made its headquarters in Florence at the Conservatorio, and he also became a lecturer in this subject.
In 1964 he organized events with the association Contemporary Musical Life that introduced in Italy the work of John Cage. In 1965 he obtained the institution of the first professorship of Electronic Music in Italy.
In 1967 he made the first experiences in computer music.
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. 
He has not limited his work to the musical world, but also engaged in contemporary art. In the eighties he was working on new forms of artistic production oriented toward the use of personal computers in the visual arts.  Grossi started to develop visual elaborations created on a personal computer with programs provided with "self-decision making" and that works out the concept of HomeArt (1986), by way of the personal computer, raises the artistic aspirations and potential latent in each one of us to the highest level of autonomous decision making conceivable today, and the idea of personal artistic expression: "a piece is not only a work (of art), but also one of the many 'works' one can freely transform: everything is temporary, everything can change at any time, ideas are not personal anymore, they are open to every solution, everybody could use them".
Grossi has always been interested in every form of artistic expression. 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. Sergio Maltagliati will continue this project creating autom@tedVisuaL software in 2012, which generates always different graphical variations. It is based on HomeArt’s BBC BASIC source code. This first release autom@tedVisuaL 1.0 has produced 45 graphical single samples, which have been sammled and published.
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).
Grossi’s latest multimedia experiments were with interactive sound and graphics. His later works involved automated and generative visual music software, autom@tedVisualMusiC 1.0 which he extended beyond the realms of music into the interactive work for the Internet, conceiving and collaborating with Sergio Maltagliati in 1997 of the first Italian interactive work for the web netOper@, entertaining in his own house study the first on-line performance. However, NeXtOper@ remains unfinished, a project to integrate new media, such as mobile phone and GPS.
- 1961 Progretto 2-3 this piece consisting of several different high monotones that follow one another, is extremely minimal and ambient, controlled by a computer algorithm.
- 1965 Battimenti an electronic work composed and realized from “working material” for the electronic Studio di Fonologia Musicale (S 2F M), made by the 94 combinations of near frequencies.
- 1969 Collage where the concepts of music being an open process where no work of music is a finished piece but rather something to be manipulated.
- 1980 Computer Music transcription and elaborations (with Soft TAUMUS synthesizer TAU2, IBM 370/168 Institutes of CNR CNUCE and IEI) from the following authors: Bach, Scarlatti, Paganini, Brahms, Chopin, Strawinskij, Debussy, Joplin, Satie, Webern, Hindemith, Stockhausen.
- 1985-90 Mixed Unicum another ambient drone piece, similar to Progretto 2-3 and yet far more varied and rewarding, as the shifting tones create an alien topography of sound.
- 1986 HomeArt Grossi has developed the concept of HomeArt. It consists of completely automated and generative visual processes, based on simple Qbasic computer programs .
