Zygielbojm's body was cremated in symbolic protest and unity with the murdered millions of the Holocaust. In 1959, his surviving son located the cremains in a shed in the Golders Green Jewish Cemetery in London. Because Zygielbojm had been cremated, the religious community would not permit his ashes to be buried in a Jewish cemetery. With the assistance of the American Jewish labor movement, Zygielbojm's cremains were brought to the US and interred at the New Mt. Carmel Cemetery in Ridgewood, New York, in 1961.
