Almost the entire working life of L.

Professor worked for 11 years in that capacity.

Becoming the Rector, L. Ribickis set the new aim of RTU: to become the third generation university that along with research and educational activities sees establishment of research-intensive enterprises as its third priority.

Aleksandrs Veiss


Professor of Chemistry
Corresponding Member of the Latvian Academy of Sciences (1975)
Rector (1963–1985)


Working at the Faculty of Chemistry since 1947, going a long way from a laboratory assistant to the faculty Dean and RPI Vice-Rector for Studies, A. Veiss acquired and developed administrative skills most appropriate in the context of tertiary education. He tried to be reasonable and did not suggest unfeasible ideas, but immediately started implementing those which could potentially be realized.

Talking about A. Veiss, Academician J. Stradiņš noted, «Aleksandr Veiss was the Great Rector of the Institute. He was a thoughtful leader and educator of the youth.»

In the mid-1960s the number of students and academic staff significantly increased. Rector’s vision was to develop a united institute campus in Ķīpsala. During his term of office many faculty buildings as well as student hostel and student canteen were erected and put into operation. A lifetime dream of the Rectors started coming to life – construction of Ķīpsala Swimming Pool was initiated.

During A. Veiss term of office extra-curricular activities were promoted and supported: artistic amateur groups, sports, student construction brigades.

Aleksandrs Mālmeisters


Professor of Materials Mechanics
Academician of the Latvian Academy of Sciences (1958), Corresponding Member of the USSR Academy of Sciences (1970)
Rector (1961–1963)


It is difficult to unequivocally assess Professor’s contribution to the field of technical tertiary education. In 1950, LSU Faculty of Architecture was liquidated on his initiative.

Although A. Mālmeisters did not consider his work at the helm of the Institute as a priority, he was a recognized scientist. His role in establishing the research school in the field of mechanics of polymer and composite materials and biomechanics in Latvia cannot be underestimated.

Assessing A. Mālmeister’s contribution to the work of the Academy of Sciences of LSSR, Academician J. Stradiņš pointed out, «... it is possible that the greatest achievements in the work of the Academy of Sciences were made at that time, however, his actions stirred very controversial feelings.»

K. Neiland’s term of office was short.

During World War II Professor received high state awards for development of the armor of T-34 type tanks, however, his nationality and «Germanic» surname were the reasons  why he was excluded from the list of Stalin Prize Laureates.

K. Neilands deserved respect from his subordinates due to his reasonable, empathetic and moderate management style. He became the leading personality in education and research of the time. He was personally involved in reestablishing the work of RPI – this is the most significant contribution of Kristaps Neilands.

Born in Jelgava. Died in Riga, buried in the 1st Forest Cemetery.

The first term of office of P. Walden as the Director of RPI occurred during the events of 1906 (a wave of mass political and social unrest), and the Director tried to take a compromise position.

Academic staff had to initiate changes and implement reforms to promote a more open and efficient cooperation, which young revolutionaries strived for.»

At that time P. Walden suggested many initiatives to improve the work of the Institute, but almost all of them could not pass through bureaucratic hurdles.

There is a version that P. Walden’s resignation was connected with his refusal to report on the students who participated in disorders to Tsar’s police (ohranka).
