Guillaume Apollinaire
Two years after being wounded in World War I, Apollinaire died in the Spanish flu pandemic of 1918; he was 38.
Luigi Molinari
Molinari died on July 12, 1918, at home in Milan after suffering a stroke in a bookstore the day prior. Among his final works was an apologetic recounting of the Paris Commune to bring the events on par with the Russian Revolution. Marxist theorist Antonio Gramsci prominently debated Molinari's points. "L’Università popolare" published its last issue later that year in memory to Molinari.
