It was only recently discovered by French athletics historian Alain Bouillé, that Michel Théato, the winner of the 1900 Marathon, was from Luxembourg, not France as was previously believed. Thus, the Grand Duchy can claim three Olympic champions, the others being the painter Jean Jacoby (1891-1936) who won Gold at the Olympic Arts competitions of 1924 and 1928, and Josef Barthel (1927-1992), the winner of the 1500m track race at Oslo in 1952.

I would be grateful for any corrections and additional biographical information.
