When?
Princess Andrew of Greece and Denmark by Philip de László, 1907. Private collection of Prince Philip, Duke of Edinburgh.
Princess Alice lived from 25 February 1885 – 5 December 1969.
In 1903, she married Prince Andrew of Greece and Denmark and became Princess Andrew of Greece and Denmark. They had had five children, one of whom was prince Philip.
She lived in Greece until the exile of most of the Greek royal family in 1917.
In 1930, Princess Andrew was diagnosed with schizophrenia. She was sent to a sanatorium in Switzerland; thereafter, she lived separately from her husband.
After her recovery, she devoted most of her remaining years to charity work in Greece.
In January 1949, the princess founded a nursing order of Greek Orthodox nuns – the Christian Sisterhood of Martha and Mary. She decided to withdraw from the world and moved to the island of Tinos.
Following the colonels’ coup d’etat in Greece in 1967 she went back to England and moved to Buckingham Palace to be close to her son and his family. She died in London in December 1969, aged 84.
