In 2020, while longtime USC Shoah Foundation indexer Ita Gordon was participating in a pandemic-era Zoom call about teaching the Holocaust in Latin America, she heard survivor Ana María Wahrenberg describe parting from a dear friend at a Berlin schoolyard in 1939. The story stayed with Ita – she had heard it before. Through several rounds of sleuthing in the Visual History Archive, Ita found the testimony: Betty Grebenschikoff, who in her 1997 interview said she was still hoping to find her childhood best friend, Annemarie Wahrenberg.
