Henri Moed, his wife Nathalie born Figatner and their son Jacques tried in August 1942 to flee from Antwerp or Brussels to Switzerland through occupied France, together with Nathalie's elder sister Sonja. They seem to have been turned back by the Swiss, though we have no archival evidence of this. All four of them were arrested in Morteau (dept. Doubs, near the border) on August 17, 1942, and transferred to the prison in Besançon on Aug. 26, before being sent to camp Pithiviers, and later to camp Drancy. The child Jacques, 10 years old, was separated from his parents either in Pithiviers, or in Drancy, and sent to the Rothschild Orphanage in Paris (7 rue Lamblardie, Paris 12e) on September 16, two days before his parents' (and Sonja's) deportation to Auschwitz. The UGIF reclaimed Jacques on February 4, 1943, which saved him from being seized on February 10 and deported (as happened to other children sent to the Orphanage on the same day).
