acad. Tiberiu Popoviciu
One of the greatest Romanian mathematicians.
One of the Romanian computer pioneers.
Appears in the select History of Approximation Theory (Technion Univ., Israel).
Some of the first electronic computers in Romania built here:
- MARICA, ’59, relay computer;
- DACICC-1, ’63, 3rd in Romania, but 1st with transistors & RAM memory;
- DACICC-200, ’68, most powerful Romanian computer; 1st with OS & compiler.

The first ionic implantation device from Romania
In the seventies was constructed a ionic implantation device.
It was subsequently improved at ITC, in 1976.
