The architect of Irish background David Mackay died at 81 in Barcelona, the city he settled in for good in 1958, after going through various countries and languages which, on hindsight, shaped his cosmopolitan character. His long and fertile career is hard to separate from those of Oriol Bohigas and Josep Martorell, with whom he collaborated as an assistant before becoming their partner in MBM (Mackay Bohigas Martorell), in 1962. Attributable to him is a list of works which are milestones in Catalan and Spanish architecture, from the Garbí and Thay schools in Barcelona to Pompeu Fabra University or the recent Disseny Hub, not to mention MBM’s most emblematic project, the Olympic Village for the 1992 Games.
