The Museum heritage, presented in the exhibition halls or kept in the store-rooms (with a view to conditioning them or keeping them as exhibition reserves), grew from donations or by transfers from the stocks of the departments. The donations include those made by or in the memory of: Valerian L. Ciofu, Radu Chisleag, Sandu Marin, Doina Mihail, Ovidiu Muntean, Mihai Popescu, Cerchez Lidia-Cecilia, Neculai Păduraru, Ştefan Paraschiv, Antonio Eleutherio Suena de Carma (Portugal), Hagin Faust (Germany), Maria Georgescu, Mihaela Andrei and Anca Dobrescu, Bogdan Carese, Vasile Toadere, Ecaterina Manilici, Silviu Dragomir, Constantin Bucur, Constantin Anton Rohr. The current exhibition, ...presented on the occasion of the museum opening, includes about 5,000 very valuable exhibits. During the period February - December 2003, five spaces were rehabilitated and refurbished, a total surface of 285 sq.m. Thus, gradually the museum stock grew, as well as the museum personnel, that in December 2003 counted 8 people. The Polytechnic University Museum opened officially on the 3rd of December 2003. The opening ceremony was held also for the commemoration of 185 years from the first engineering lectures in the Romanian language by Gheorghe Lazăr, in Bucharest, at St. Sava School and of 135 years from the first document attesting the existence of the Central Library of the School.
