The French freestyle relay team stunned the world by winning the gold medal in the 4x100 meter contest by defeating the Americans.
But there was another surprise.
Fabien Gilot raised his arm in victory to reveal a moving tribute in Hebrew:
אני כלום בלעדיהם, meaning "I am nothing without them."
Gilot explained that it was a tribute to Max Goldschmidt, a Jewish grandfather figure.
Goldschmidt, who grew up in Germany and was an Auschwitz survivor, moved to France where he met Gilot's grandmother. Despite not being his biological grandfather, Goldschmidt was an important and inspirational person in Gilot's life, and "a grandfather in every way," Michael Gilot, Fabien's father, told YNet.
Goldschmidt died earlier this year.
This is not the only moving tribute to a Jewish figure at this year's Olympic Games in London. The same day that Gilot revealed his Hebrew tattoo, the Italian delegation to the Olympics held a minute of silence with the Israeli team to commemorate the 11 victims of the 1972 Munich massacre.
