Rachel Margolis was born in Vilna (Vilnius), Lithuania, in 1921. In 1941 Nazi Germany invaded Lithuania and Rachel was sent to live in hiding with a Christian family. A year later, she decided instead to move to the Vilna Ghetto; a ghetto so terrible that over the two years of its existence, the population fell from 40,000 to only a few hundred. During her time in the Vilna Ghetto, Rachel joined the Fareinikte Partisaner Organizatzie (the United Partisan Organization), headed by Abba Kovner.
When the ghetto was liquidated in 1943, under the orders of Reichsführer of the SS, Heinrich Himmler, Rachel and her future husband escaped to the surrounding forests. Although they faced the constant threat of starvation and disease – not to mention capture by their oppressors – the partisans actively fought back by blowing up Nazi lines of communication.
The sole Holocaust survivor in her family, Rachel went on to gain a Ph.D. in biology and worked as a teacher until the late 1980s. In 2005, Rachel found and published the diary of Kazimierz Sakowicz, a Polish journalist who witnessed the Ponary massacre of 1941 to 1944, which killed up to 100,000 people, the majority of whom were Jews. In 2010, Rachel published her own memoir, A Partisan from Vilna, chronicling her early life and battle to survive Nazi oppression during World War II.
