Sunday 7th April 1935
Joseph Cattanéo driving a 1500 cc racing Bugatti skidded into the crowd at the Château-Thierry hillclimb, just 100 metres from the finish, killing 7 and injuring 18. Later that year, Cattanéo was acquitted in court while the organiser of the event, Victor Breyer, had to pay a fine of 200 Francs and hundreds of thousands of Francs compensation to the survivors as well as to relatives of those killed.
