Niki Lauda, Christian Fittipaldi, Michael Schumacher and Gerhard Berger re-established the GPDA over the 1994 Monaco Grand Prix race weekend, following the events of the preceding San Marino Grand Prix, which culminated with the deaths of Ayrton Senna and Roland Ratzenberger, during the Sunday race and Saturday qualifying respectively. Shortly before his own fatal accident, and following the fatal accident of Ratzenberger and the serious accident of Rubens Barrichello during Thursday practice, Senna spent his final morning on the Sunday talking to former teammate and rival Alain Prost to discuss the re-establishment of the GPDA and had offered to take the Chairman role starting from the Monaco Grand Prix.
