In an age of rising anti-Semitism, fascism, and Holocaust deniers, it is critical that the world never forgets what happened to the Jewish people during WWII. On Sunday, April 8, at 2:00, the Museum of Jewish Heritage — A Living Memorial to the Holocaust will cohost New York’s Annual Gathering of Remembrance at Congregation Emanu-El. Held in conjunction with the holy day known as Yom HaShoah, which begins Wednesday night, the memorial service is a “tribute to those who survived and have made a better world for us all,” with elected officials, Holocaust survivors and their families, and other members of the community coming together at the Upper East Side synagogue. On its website, the Museum of Jewish Heritage explains, “Every year, at New York’s Annual Gathering of Remembrance, we come together as a community to say: We will never forget. The Jewish people persist, and we will not allow the memory of millions to pass into stony silence. We owe it to our people, ourselves, and our children to insist that when we mourn those who were murdered and comfort those who suffered, we tell their stories with the utmost respect for their human dignity. It is a powerful answer to the Nazis’ thwarted ambition. New York’s Annual Gathering of Remembrance is the largest Holocaust commemoration event in the country.” Tickets are free but must be reserved in advance here; printouts must be presented at the door.
