Patricia Mary St. John (1919—1993) was an English writer. She worked most of her life as a missionary nurse in Morocco. Although at first she worked with her brother in the main foreign hospital, she later spent four years manning a village clinic in a more remote area.
Her parents, Harry and Ella St. John, had been missionaries to South America for two years. Patricia was born, the third of five children, just after they arrived back in England.
From her memories of a year lived in alpine Switzerland she wrote her second book, Treasures of the Snow.
After finishing high school she became a nurse during World War II, and after the War ended was a house mother at her aunt's boarding school for a couple of years before she joined her brother, Farnham, in Tangiers, Morocco, where he was medical director of a Missions hospital.
