Pedro (Pere) Rosselló i Blanch (Calonge, Spain 1897–1970), was a Catalan lecturer and educator.
He served as the deputy director of the International Bureau of Education (IBE) from 1928-1969, a position which he took over from Elisabeth Rotten.
Working alongside director Jean Piaget, he played an integral role in shaping the IBE during its inception as an international organization until its merger with UNESCO in 1969.
[1] Rosselló completed his studies in Education first at the Escola Normal in Girona, then at Madrid Teacher's College, and followed his graduate studies at the Geneva Institute of Sciences of Education and at the University of Lausanne, completing his doctorate in social sciences at the latter in 1934 with the dissertation "Marc-Antoine Jullien, pére de l'éducation comparée".
He collaborated with fellow Rousseau Institute colleagues Edouard Claparède and Adolphe Ferrière in turning the IBE into an intergovernmental organization, a status it achieved in 1929.
