William Reginald Alcorn was born in Zambia in 1950 to Irish and Scottish parents. He developed a passion for painting at a very early age. After studying humanities in England, he travelled around Europe, eventually settling in France. With projects in music, languages, science and, more recently, mathematics, he divides his time between his painting studio and popularising the arts, notably as part of the activities of the IREM of Limoges.
