The Olivetti company was founded by electrical engineer Camillo Olivetti (1868-1943) in 1908. The 40-year-old Olivetti established a factory in his home town of Ivrea in northern Italy, and initially produced a range of typewriters to his own design. As the business expanded in the 1920s and 30s the company established branches in Spain and in several South American countries. A very successful range of mechanical printing calculators was added during the reconstruction period following the 1939-45 war. The company expanded into the American market with the purchase of the Underwood typewriter company in 1959.

Olivetti moved successfully into electronics with the production of a mainframe digital computer (the ELEA 9003) in 1959, and a programmable desktop calculator/computer (the Programma 101) in 1964. The company had several changes of ownership and direction during the 1970s, 80s, and 90s, with new interests in personal computers, office equipment, and telecommunications. The company became part of Telecom Italia in 2003, and celebrated its 100th birthday in 2008. Electronic calculators are still made and sold under the Olivetti name.
