In the building at Wilczyńskiego 4 (former Rogowska Street) was a butcher’s shop, which belonged to Aaron Elster’s parents. After the World War II he wrote a book about his life “I Still See Her Haunting Eyes: The Holocaust & a Hidden Child Named Aaron”. He describes: “My parents have butcher’s shop on Rogowska street. Over the entrance there is a hand-painted sign showing carcass and chopper. My mother serves customers. At first she weighs portions, then adds some extra meat or bones. Our shop is unusuall, because we sell non-kosher meat. Our customers are not Jews.” Aaron and his sister, Irene were hid by Polish Family for two years until the War’s end. All of them survived War.
