Identity of Tannenbaum

I am seeking genealogical information on Mark (Mosha) Tannenbaum. He was born on about 1928 in a part of eastern Europe that latter was under soviet control, most likely Belarus. His family was killed in a concentration camp during WWII. He later emigrated to Israel and served in the Israel army. On about 1957 he was a teacher in a synagogue in Lewiston/Aurborn Maine in the USA.
