The best-selling Christmas song of all time, White Christmas, was written by a Jew whose own Christmas tradition was visiting the grave of his son who died on Christmas day in 1928 at the age of three weeks old. That son was Irving Berlin, Jr. Irving Berlin was not his birth name. He was actually born Israel Beilin and immigrated from Russia. He wrote many other well known classics that are too numerous to list. He was one of the all time great songwriters.
