This is Octave Lapize.
He won the 1910 Tour de France, and a bronze medal in the 1908 Olympics. He won Paris-Roubaix three times, in 1909, 1910 and 1911.
He is famous for, on the Col du Tourmalet during the 1010 Tour, yelling at race organisers “Vous êtes des assassins! Oui, des assassins!”
That day was 326km over seven major climbs. On unsealed roads. On a heavy fixed gear bike. I see his point.
He went on to become a fighter pilot in the French army, and was shot down and killed over Moselle, in the Lorraine region of France.
A cycling legend and a fighter pilot. What a charismatic man.
