I justy found this fascinating:
Myer Lewis, who served under the Canadian flag in World War I and the U.S. stars and stripes in World War II, has died. He was 104. He gloried in victory parades in London at the cessation of European fighting in both wars — after the November 1918 armistice and after V-E Day in May 1945 — and remembered both as “a big, big thrill.” “My part in World War I and World War II was very small, but I was happy to do what I could for these two great countries,” Lewis said three years ago in Cupertino, Calif., when the government of Canada presented him the McCrae Medallion and Queen’s Certificate in gratitude for his service during the Great War.
The son of a career soldier in the British Army, Lewis was born in London in 1899, and moved with the family to postings in South Africa and Malta before immigrating to Ottawa, Canada, in 1910. Later working as a clerk there, the teenage Lewis enlisted with the Motor Transport Unit of the Canadian Army Service Corps as part of its World War I 4th Expeditionary Force. Although Lewis was 43 as the U.S. built up forces for World War II, he enlisted in the Navy with Fleet Air Wing 7. He returned to England, serving in the Dunkeswell area in antisubmarine patrols. Three years later, he remembered escorting in the first German U-boat to surface after Germany’s surrender on May 8, 1945.
Both wars brought him into contact with celebrity entertainers — Sarah Bernhardt after the Great War, and Irving Berlin and Kate Smith during World War II. Mentally sharp until his death, Lewis, who lived in three centuries, was asked what he considered the most important advancement of the 20th. Without hesitation, he said, “the silicon chip.”
