I want to thank all those who responded to my query about Leib KUPERSHMIDT.
from your responses I learnt that Leib KUPERSHMIDT born 1928 in Kaunus,Lithuania and immigrated 1935 to NY became Leo KUPERSHMIDT and under this
name was serving in the US Forces in Japan in 1953 during which time he took
part in chess tournaments.
In later life he was an accountant named Leo COOPER.
There is a listing for a Leo COOPER, accountant, in Brooklyn but the phone
number is not operative.
It appears that at some stage he may have lived in Deerfield Beach, Florida.
Will be grateful for any leads to my elusive second cousin and/or his
Kibbutz Yizreel, Israel
