Montserrat Carreras, historian and head of the Historical Archive of the City of Badalona, will offer us the lecture El Eco de Badalona, dean of the local press, on the occasion of the presentation of the digitalization of this magazine, founded in 1868. In February the Eco will be available in the Museum’s website. The Eco, which had a weekly character, is an essential source for learning about the history of Badalona from the end of the 19th century until the beginning of the Civil War (1936). This consultation platform will contribute to the preservation of the originals and to make this source known, both to researchers and scholars and to the general public. The lecture will also be a tribute to the founder of El Eco de Badalona, Francesc Planas i Casals (1845-1911), on the occasion of the 175th anniversary of his birth.
