Prix Jean Prat
The Prix Jean Prat for older horses was renamed the Prix Vicomtesse Vigier in 1985. This was in honour of Vicomtesse Vigier, Madeleine Double de Saint-Lambert (1869–1970), the niece of Jean Prat, who inherited her uncle's stable upon his death. The version for three-year-olds continued with the title Prix Jean Prat.
