Guillaume Apollinaire
Two years after being wounded in World War I, Apollinaire died in the Spanish flu pandemic of 1918; he was 38.
Guillaume de Ferrières (cardinal)
Business concluded, the party began its return journey. Cardinal Guillaume only got as far as Perpignan where he fell ill, and died on 7 September 1295. He was buried in the Franciscan church in that city. Unaware as yet of his death, Pope Boniface wrote a letter to Cardinal Guillaume on 19 September, in which he remarks on Guillaume's illness and his frustration that the negotiations with King James of Aragon were being delayed.
