It was not until the age of 38 that he committed himself to becoming a painter. He was born in 1938 in Bangalore to a military civil service family, "returning" to England when he was seven. He eventually gained a scholarship to study at the Coventry School of Art. However his focus shifted and he took a degree in husbandry and manure. He earned a living in a variety of ways; farming, shoemaking, a six-year period in the Royal Artillery near horses which he loved, scene-painting, building, decorating and as an illustrator. He studied part time at the Heatherly and Sir John Cass schools of art and eventually, in 1978, gained a place in the fine art department of Hornsey School of Art, at the then Middlesex Polytechnic. It was abundantly apparent that Caswell did not fit into any category that such a department might expect.

He used the place as his own - as indeed all people studying should, it was just that his manner was particularly vigorous. He came to learn to draw and paint in order to fulfil his driving ambition to meet adequately the poetic imagery teeming in his mind. He paid no attention whatsoever to the fashions of the art world that are reflected in art schools He had his vision; he let others search around for theirs. He was a weaver of legends and tales and he set about doing this in drawing, painting, print- making and even film.This was a time when the course had first become involved with work in the community - in schools and hospitals - and when students of fine art could step out of their academic isolation and into the world of people, hoping to share experience through art. In his first year at Hornsey, Caswell took up an opportunity in a local hospital, in the geriatric ward of Colindale Hospital, Middlesex. The result was sensational, both in human and artistic terms. Through the carnival mural that he created Caswell discovered his metier: to give pictorial articulation to poetry and story.It was therefore not difficult to realise that Caswell was the person to take up the challenge of a mural for the Great Ormond Street Hospital for Sick Children when the hospital contacted Hornsey Caswell knew Great Ormond Street's connection with J.M.

Barrie's book Peter Pan, and this became the theme for the mural.He commandeered studio screens to set up paper for a full-size cartoon of the 72ft by 8ft project. His manner of proceeding was not entirely popular but the drawing showed a spectacular command of theme, idea and draughtsmanship. He gained the commission and set to work on site.It took eight years to complete, plus a further six weeks seven years later. He worked on it largely from 8pm to 8am to keep out of the way of hospital "traffic".
