Mary Evelyn Lentaigne (6 May 1920 – 29 April 2024) was a British medical artist and Red Cross Voluntary Aid Detachment nurse who worked at the Queen Victoria Hospital, England, during the Second World War.

[3] Sir John was himself the grandson of the surgeon Benjamin Lentaigne who was born in France in 1773, but, as a Royalist and firm supporter of King Louis XVI, was forced to escape to England at the age of nineteen.

He was posted to the Dublin barracks in 1775, and was involved in the treatment of Wolfe Tone, the leader of the 1798 Irish Rebellion, during his imprisonment and the final days of his life.

[4][5] During the Second World War, Lentaigne worked as a Red Cross Voluntary Aid Detachment nurse at the Queen Victoria Hospital, East Grinstead, West Sussex, where her duties included drawing the experimental operations of Archibald McIndoe and his fellow surgeons.

[11] After the surviving Guinea Pig Club members used social media to search for Lentaigne and found her living in Zimbabwe, she returned to East Grinstead in 2013 to be reunited with her work.
