Rene (Claude) Phelizot was from Chicago, IL.
From: American fighters in the Foreign legion, 1914-1918 by Paul Ayres Rockwell:
Phelizot was one of the most beloved volunteers in the Legion, and one of the most helpful and generous. At Christmas time he sent from the trenches four hundred dollars toward a fund to buy gifts for poor Paris children. On the march he was ever ready to help weaker comrades by carrying their rifles or packs.
Page -42- Phelizot was one of the best-known big-game hunters and elephant-killers in Africa, where he had lived for years.
