She continued to live independently in Belsize Park, north London, after turning 100 and went swimming every day up to the age of 97.

In her later years Ms Sommer-Herz reflected: "I have never hated, and I will never hate."
Following her death on Sunday, her grandson, Ariel Sommer, said: "Much has been written about her, but to those of us who knew her best, she was our dear 'Gigi'.
"She loved us, laughed with us, and cherished music with us.
"She was an inspiration and our world will be significantly poorer without her by our side."
A documentary about Ms Sommer-Herz's life is nominated for an Oscar at next week's Academy Awards.
Holocaust Educational Trust chief executive Karen Pollock said: "With the passing of Alice Sommer-Herz we are once again reminded that Holocaust survivors will not be with us forever.
"We must all take on the responsibility to ensure that the horrors they endured are never forgotten. Our thoughts are with her family.”
