As early as 1941, Wilson was described as having "driven a car through various parts of the continent ... he can ride a horse, keeps a bob-tailed collie, favours Chinese, Japanese, Indian and Mogul painting and lives any odd way that suits him at the moment."
Wilson's first nature book, a study of monkeys, was published in 1937 and was followed with studies of dogs and a variety of zoo animals, published after the Second World War. His water colour paintings attracted the attention of the British Museum and Natural History Museum, where he helped reconstruct the look of dinosaurs from fossils. His work in this area was much respected and the Natural History Museum website notes:
Wilson's style was very versatile, but he is best known for his prehistoric reconstructions. His talent for representing prehistoric life lay in his ability to bring to life creatures never seen by humans by giving a sheen to feathers, or by using a light and dark contrast to hairs of mammals. By painting scenery in a realistic way, he also gave his subjects a definite scale and placed prehistoric animals in an historical context.The later Prehistoric Animals by Barry Cox (1976) was produced in association with the Thames Television series and Wilson was also a graphic designer on the TV documentary Life on Earth (1979).
His anthropological work can be found in Peter Andrews and Chris Stringer's publication Human Evolution: An Illustrated Guide (1989), with his animal reconstructions published in W. E. Swinton's very popular handbooks which included Fossil Amphibian and Reptiles (1954) and Fossil Birds (1958). Wilson also illustrated Wilfrid Le Gros Clark's, A History of the Primates (1949) with a series of fine black and white drawings whilst other illustrations have accompanied displays in the Museum's public galleries.
e of a Neanderthal family painted in 1950, featured Giles Oakley and his brother as models for two young Neanderthals having a childish scrap. He later recalled:
Maurice was a real character, as I recall from his regular and keenly-awaited visits to our home in Amersham, Bucks, some thirty-odd miles from London. An eccentric, bohemian dresser, he'd bound out of the car and stride up the front path clad in a long coat with string round the waist plus open-toed sandals and a raffish cravat at his neck. His hair was worn fairly long in oiled ringlets like a stereotypical gypsy, making him for years my image of what 'an artist' was like, not unlike some Agatha Christie suspect. He had a beguiling approach with children, never talking down to us but full of little tricks and jokes to keep us entertained, although it was always clear that he was deeply serious about his work as a natural history illustrator.
My parents greatly admired his artistic skill which was characterised by a deceptively simple mastery of line and shading, enriched by subtle colour washes and an overall softness of tone. Several of his paintings and prints used to adorn the walls at home in Amersham and they are still much loved in the family. One of those I inherited used to hang above my father's desk in his study, a large sketch Maurice did in April 1950 of 'Australopithecos', looking faintly melancholy and soulful, as though dimly conscious of his evolutionary fate. Whether conjuring up an imagined past in deep antiquity or simply painting feathers and fur from direct observation, there was always a warmth and humanity about Maurice's work, often caught in the poignant expressiveness of a creature's eyes.
Wilson's autobiography, The Wartime Adventures of B Squadron 'Corpse' (1997), was publishing posthumously, relating how he joined the 11th Battalion Royal Tank Regiment in 1941 and spent much of the war in a Matilda tank, weathering sandstorms in the Middle East, taking part in the landings at Walcheren and in the 'CDL' experiment which involved placing blindingly bright carbon arc lamps in the turrets of tanks to create a wall of light when the tanks were lined up—an idea that was never used in battle.
Wilson lived in Tunbridge Wells, Kent, where he died in November 1987.
