Irwin was primarily known as a landscape and figure painter. His permanent home was in Leamington Spa in 1940, but prior to that time he had studied at Juliens Academy, Paris and at the Academie Beaux-Arts in Brussels. His addresses were in London (1933), Ewell, Surrey (1935) and then in Warwickshire (1940).
His connection with Cornwall and STISA was in the final year of his life, though Whybrow had noticed his presence earlier in her 1921-1939 list of artists in and around St Ives.
