Alan Seeger was born in New York. Seeger entered Harvard in 1906 after attending several elite preparatory schools, including Hackley School. At Harvard, he edited and wrote for the Harvard Monthly.
After graduating in 1910, he moved to Greenwich Village for two years, where he wrote poetry and enjoyed the life of a young bohemian.
Having moved to the Latin Quarter of Paris to continue his seemingly itinerant intellectual lifestyle, on August 24, 1914, Seeger joined the French Foreign Legion so that he could fight for the Allies in World War I (the United States did not enter the war until 1917). He was killed in action at Belloy-en-Santerre, famously cheering on his fellow soldiers in a successful charge after being hit several times himself by machine gun fire. One of his more famous poems, I Have a Rendezvous with Death, was published posthumously. Indeed, a recurrent theme in both his poetic works and his personal writings prior to falling in battle was his desire for his life to end gloriously at an early age.
Seeger's poetry was not published until 1917, a year after his death.
