Margot would later go into hiding with Anne, her family and the Van Pels family, before being discovered in 1944.
They were deported to the Westerbork concentration camp, then to Auschwitz. Margot and Anne were then taken to Bergen Belsen, where both contracted Typhus and died.
Teresien da Silva, Head of Collections at the Anne Frank House, said: “Margot was a beautiful, bright, and sporty girl.
"We already had some pictures of Margot on skis, on ice skates, and on the tennis court, and now we also have photos of Margot with her rowing club.
“These new photos show a cheerful girl, enjoying herself with her crew mates. They are a delight.”
