Obituary for Carles Perelló

We are deeply saddened at the recent passing of Carles Perelló, who was one of the founding members and Editor in Chief of Publicacions Matemàtiques in the period 1993-1994. He was 88 years old, and had been a member of the Mathematics Department of the UAB for more than three decades. He will live on in our memories for his constant desire to communicate mathematics, both pure and applied and, above all, his warmth as a human being.
