Jules Crochet in Mareuil-le-Port (51), Marne (51)

Jules Crochet (1902-72*) was born in Dormans, died in Tinqueux near Reims, and was a pioneer of medical aviation. In the 1930s he carried out medical missions in Africa for the French government. A roundabout in Reims was named after him in 1997.

*Wikipédia at the time of writing gives the date of his death as 1974, which clashes with the date of the plaque on his family vault.
