Luigi Dadda (April 29, 1923 – October 26, 2012) was an Italian
He studied
.His research interests then turned to models and analog computers as an assistant professor, and in 1953 he received a grant from the
He would travel to Italy on an old Liberty merchant ship along with the precious machine, packed in cotton balls in order to protect its valves from dangerous vibrations. Upon disembarkation in Genoa, the machine was declared with customs as an "electrical appliance", as the only computer machine in the taxonomy of goods used at the time was a "punchcard machine", but a punched card reader was not supplied with the computer, so it didn't fit the categorisation. An additional problem was that, at the time, Italy's taxation imposed the application of a small paper slip similar to a stamp (proving payment of duties) on each and every valve used in the machine. Since dismantling the machine to apply the slips was out of question, the customs allowed Dadda to pay the tax as a forfeit and gave him a pack of slips to apply on the machine "as soon as possible". Those slips remained in a drawer in Dadda's desk.
The machine reached, at last, the Politecnico di Milano in September 1954, where it was activated in the 2SUD back room, and became the first working digital computer in Italy and continental Europe. In the following years, the research activity of Dadda focused on the use of the machine for scientific and industrial applications, and training researchers and students of the Politecnico in Computer Science, where he created and taught the first courses on the subject. Notably, he studied how to enhance the ALUs of the machines, proposing solutions such as the Dadda multiplier, which significantly enhanced performance of those circuits.
He reached the status of a full professor at the Politecnico in 1960 and was assigned the
He was a founding member of the Italian Association for Computing in 1961 (and President between 1967 and 1970) and a co-founder and director of the distinguished Italian journal of computer science: Rivista di Informatica. He was the proposer of the European Information Network, realized by
He died on October 26, 2012, in Milano, Italy at the age of 89.
In 2016 the prestigious "IEEE Milestone award" has been assigned to his memory in recognition of his contributions.[4]
