The London Jewish Cultural Centre marked HMD by mounting an exhibition of paintings by survivor Alicia Melamed Adams.
It was opened by Suzanne Bardgett, head of research at the Imperial War Museum, who has written about the artist's life and work in the soon to be published Justice, Politics and Memory in Europe after the Second World War.
She explained to guests how Ms Melamed Adams, who survived the Holocaust in the Polish town of Drohobycz, settled in England after the war and began studying art only when the French class she had hoped to join was full.
While studying at St Martin's School of Art in 1963, she painted a series of works recalling her traumatic past. They were kept hidden in her studio for many years but have since been exhibited regularly.
Two paintings have been purchased for the collection of the Imperial War Museum.
The artist said she was not good at public speaking but thanked Ms Bardgett for bringing her work to a wider audience.
