Biography
Pier Giorgio Perotto, born on December 24, 1930, in Turin, Italy, became a key figure in the early days of personal computing. He studied electrical engineering at the Polytechnic University of Turin and the University of Turin, which provided the technical foundation for his career. Perotto passed away on January 23, 2002, in Genoa, leaving a legacy that made computers more accessible to individuals rather than just large institutions.
During his career at Olivetti, the well-known Italian company famous at the time for its typewriters and office equipment, Perotto found the support he needed to explore forward-thinking ideas for the early 1960s. He led a small, focused design team with the goal of creating a machine for programmable calculations that offices and professionals could actually use and afford.
This effort resulted in the Programma 101, which debuted at the 1964 New York World's Fair and became available in 1965. The machine was small enough for a desk, programmable with magnetic cards, and could store and execute instruction sequences. Many computing historians view the Programma 101 as one of the world's first programmable desktop calculators, released years before other similar products. NASA reportedly bought several units for calculations related to the Apollo program, highlighting the machine’s practical capabilities.
In addition to his engineering achievements, Perotto wrote about the history of the Programma 101 and the broader evolution of computing. He authored a book in Italian detailing the project’s origins and its significance in technology’s progress, offering an insider perspective on how a small team in a traditional manufacturing company managed to innovate a new kind of device.
Perotto’s career shows that innovation in computing during the mid-twentieth century was not limited to the United States or big government and university labs. From Turin, in a company known for mechanical office tools, he and his team showed that creating a programmable machine for individual use was possible with the technology and resources of the time.
Before Fame
Perotto grew up in postwar Italy, during a time when the country was rebuilding its industrial base and nurturing a new generation of technically educated professionals. Turin, where he was born, was the heart of Italian industrial and engineering culture. It was home to major manufacturers and institutions like the Polytechnic University of Turin, which trained the engineers who worked in these industries. Perotto's education there, along with his studies at the University of Turin, gave him a strong background in both theoretical electrical engineering and practical industrial application.
By the time Perotto joined Olivetti, the company was already exploring electronic technologies alongside its main mechanical products. Italy's postwar economic growth led to increased demand for more efficient office tools, and Olivetti was investing in what those tools might become. Perotto entered this scene as a young engineer, well-prepared to engage with the new electronics field. He was eventually given a project to create a machine for which there was, at the time, no established commercial category.
Key Achievements
- Led the Olivetti design team that created the Programma 101, one of the world's first programmable desktop calculators
- Oversaw the development of a programmable machine compact and affordable enough for office and professional use, years before such devices became standard
- Contributed to early computing history through written documentation of the Programma 101 project and its technological significance
- Helped establish Italy as a contributor to the global development of computing technology during the 1960s
- Produced a machine adopted by NASA for use in calculations connected to the Apollo space program
Did You Know?
- 01.NASA purchased several Programma 101 units and reportedly used them in planning calculations for the Apollo moon missions.
- 02.The Programma 101 used removable magnetic cards to store programs, allowing users to save and reload their own instruction sequences.
- 03.Olivetti introduced the Programma 101 at the 1964 New York World's Fair, roughly a year before it went on sale commercially.
- 04.Perotto wrote a book in Italian documenting the development of the Programma 101, providing one of the few firsthand accounts of the project's history.
- 05.The Programma 101 weighed approximately 29 kilograms and was priced at around 3,200 US dollars at launch, making it far more accessible than the mainframes of its era.
