Uniform to Emil Nelson, 127th Ambulance Co/ 107th Sanitary Train/ 32nd Division. Emil was a Dutch immigrant who moved to Racine, Wisconsin with his family. He joined the Wisconsin National Guard , assigned to Ambulance Co #2 (Racine). When war was declared, Wisconsin (Racine) Ambulance Co #2 became the 127th Ambulance Company in its entirety (much like the “pals” units in 1914, the whole unit was drafted from the same town).
Emil was originally discharged from the Army due to his chest size being too small; but was quickly reinstated when war was declared. He survived, and married a pretty Dutch girl in Racine after the war.
