Menachem Z. Rosensaft
Menachem Z. Rosensaft (born 1948 in Bergen-Belsen, Germany) an attorney in New York and the Founding Chairman of the International Network of Children of Jewish Survivors, is a leader of the Second Generation movement of children of survivors, and has been described on the front page of the "New York Times" as one of the most prominent of the survivors' sons and daughters. He also served as National President of the Labor Zionist Alliance, and was active in the early stages of the Israeli-Palestinian peace process. As psychologist Eva Fogelman has written: "Menachem Rosensaft's moral voice has gone beyond the responsibility he felt as a child of survivors to remember and educate. He felt the need to promote peace and a tolerant State of Israel as well. He wanted to bring to justice Nazi war criminals, to fight racism and bigotry, and to work toward the continuity of the Jewish people".

In 1937, he moved to New York. In 1948 Rosenbaum arrived in Cuban on a charity collection mission for the Israeli Irgun. He soon became the Rabbi of Adath Israel-K’neseth Israel, then later rabbi of the Patronato.
