In a recent TikTok video, 98-year-old Lily Ebert told her 1.9 million followers about the Auschwitz number tattooed on her forearm: A-10572. Like many Holocaust survivors, Ebert didn’t talk about the experience for decades. But then her great-grandson Dov Forman started recording her stories and posting them on TikTok, including the 24-second video about her tattoo that has drawn more than 22 million views. “We were a number and we were treated only like numbers,” Ebert said in the video.
