Margaret Fountaine was the eldest of seven children born to an affluent English clergyman. Her mother was a domineering and conservative woman and Margaret sought every opportunity to escape from home. At age 27, she became financially independent through an inheritance from a paternal uncle. In 1895, after visiting Henry John Elwes, a noted botanist and entomologist, Margaret began her own serious butterfly collection. In 1901, she met Khalil Neimy, who became her companion and guide for 27 years. Her quest for new butterflies led Margaret to travel by air, sea, rail, and on horseback to six continents over 50 years. Her sketchbooks are preserved in the Natural History Museum, South Kensington, London, and provide important insights into the life and work of this intrepid Victorian naturalist. Margaret Fountaine died of a heart attack in Trinidad while on a collecting trip.
