This paper aims to build a theoretical-methodological approximation between Public History (PH) and Oral History (OH). First of all, beyond presenting our conceptual perspective about HP, we carried out a reflection on the historicity notion of PH in England, United States and Brazil, pointing their several interactions with OH. Later, supported by an extensive documental research, we have rigorously investigated the Oral History senses and the role attributed to the historian and to historical knowledge during the founding of Oral History Lab of University of the Joinville Region (LHO/Univille). We have analysed how, in the beginning of 1980' s, it was idealized as part of a huge network, involving numerous universities from the South of Brazil, as well as international multilateral actuation institutions, like Organization of American States (OAS), and Secretaria de Cooperacao Tecnica Internacional do Brasil (Brazilian International Secretary of Technical Cooperation), at that time subordinated to Education and Culture Ministry (SUBIN/MEC). Finally, some considerations were done about reflective limits and possibilities of PH when articulated with Oral History as well as about latest discussions focusing the public role of the historians on History of the Present time.
