Vladka Meed, born Feigele Peltel, served in the Jewish underground in the Warsaw Ghetto by passing as a Christian outside its walls. Immediately following the Second World War, she settled in New York City with her husband. Her memoir, On Both Sides of the Wall, one of the first eyewitness accounts of the Holocaust, was first published in Yiddish in 1948. She remained extremely active in Holocaust education and memorialization until her death in 2012.
