The name of John McCrae (1872-1918) may seem out of place in the distinguished company of World War I poets, but he is remembered for what is probably the single best-known and popular poem from the war, "In Flanders Fields." He was a Canadian physician and fought on the Western Front in 1914, but was then transferred to the medical corps and assigned to a hospital in France. He died of pneumonia while on active duty in 1918. His volume of poetry, In Flanders Fields and Other Poems, was published in 1919.
Today is Remembrance Day in Canada and many other countries
P.S. in Wikipedia there is a photo of the original handwritten poem and it is 'grow' not 'blow'!
