     The engineer Camillo Oliver was 40 years old when he started the company in 1908.

     At his factory in Ivrea, he designed and produced the first Italian typewriter. Today the company's head

office is still in Ivrea, near Turin, but the company is much larger than it was in those days and there are

offices all around the world.

     By 1930 there was a staff of 700 and the company turned out 13,000 machines a year. Some went to

customers in Italy, but Olivetti exported more typewriter to other countries.

     Camillo's son, Adriano, started working for the company in 1924 and later he became the boss. He

introduced a standard speed for the production line and he employed technology and design specialists. The

company developed new and better typewriters and then calculators (计算机). In 1959 it produced the ELEA

computer in Italy.

     After Adriano died in 1960, the company had a period of financial problems. Other companies, especially

the Japanese, made faster progress in electronic technology than the ITalian company.

     In 1978, Carlo de Benedetti became the new boss. Olivetti increased its marking and service networks and

made agreements with other companies to design and produce more advanced office equipment. Soon it

became one of the world's leading companies in information technology and communications. There are now

five independent companies in the Olivetti group-one for personal computers, one for systems and services,

and two for telecommunications.
