The daughter of James Fawcett, and his wife Frances Beatrice Lowe, she has a brother and three sisters. Her maternal grandparents, who were American, were palaeographer Elias Avery Lowe and translator Helen Tracy Lowe-Porter. Elias was a Russian Jewish immigrant to the U.S, while Helen was from Pennsylvania. Her great-great-aunt was poet Charlotte Porter.
She read English at Oxford University, and was the first married female undergraduate at Lady Margaret Hall. She interrupted her studies to go to the US with her husband Stanley Johnson whom she met at Oxford and married in Marylebone, London in 1963. She later returned to LMH with a baby and pregnant with her second child to sit Finals in 1965. She was awarded a second class honours degree.
Johnson Wahl is recorded as having "made her name as a professional portrait painter" for the likes of Crispin Tickell, Joanna Lumley, Jilly Cooper, and Simon Jenkins, but is "also known for her vibrant and edgy urban landscapes", which have been described as echoing the Vorticist style.
She continues to paint. Her paintings sell at prices from £1,000 to £5,000 for a large one. Two of Wahl's paintings are in the collection of the Bethlem Museum of the Mind; another two are in the collections of Oxford University colleges.
