A polite and conservative person, dedicated one hundred percent to his work, Carlos Pérez de Rosas Masdeu was the founder and patriarch of one of the most important photo-journalistic dynasties of this profession's history in Barcelona. Born in Madrid in 1893, at the heart of an upper class family very closely connected to intellectual, political and military circles, he started to work at an age of 17 at the newspaper Las Notícias, where he carried out all sorts of assistant tasks.
