Leslie "Les" Lane was born in Sydenham, London in 1905. He was the fourth child of John Edmund Lane, a stone carver, and Beatrice Elizabeth Lane, who ran a boarding house for actors on Drury Lane. Les died in 1993 in the Bahamas, where he had spent much of his life, living in a single-storey house at Dead Man's Reef, near West End on the island of Grand Bahama. 
The 1911 Census shows Les aged 6, living with his family at 50 Elm Grove, Peckham, South London. His father's occupation is listed as "Stone cutter (stone mason)" 
Leslie Lane attended school in Sydenham and, like his father, and other members of his family, he became an artist. He was a painter and commercial artist - mainly a photographic retoucher. He emigrated to Canada in around 1917 along with the rest of his family, aged 12. 
In Toronto, Les founded a commercial art studio known as The Les Lane Studio, which he ran with Kay. 
Les Lane left Kay in 1935, just 2 years after Richard was born. They divorced, and Les moved to Nantucket, where he married a French woman named Catherine, whose portrait he painted. 
During WW2 Les served with the US Army in Italy, under General Arthur R. Wilson, whose portrait he also painted. 
After the war Les was posted to Paris, where he had an artist's studio in Montmartre and apparently painted Marlene Dietrich. 
In about the 1940s and 1950s Les ran a summer painting school at Pocomo Head, Nantucket known as the Leslie Lane School of Art, with a friend Anton Bruehl.
