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).

MARICA Computer (1959), Tiberiu Popoviciu Institute of Numerical Analysis, Romanian Academy
DACICC-1 (1963) electronic computer, in complete configuration
The DACICC-200 computer (1968), installed at Bucharest (1969), operated by engineers Petre Soreanu, Mircea Bocu and Gheorghe Farkas

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.
