Born in Morpeth, Crawhall was one of the most talented and highly regarded artists ever produced by Scotland. His favourite subjects were horses, dogs and other animals, often painted on linen or silk. He is recognised as one of the most important horse painters of the twentieth century and his intimate knowledge of animals and birds can also be clearly seen in his work.
A great perfectionist, he once discarded a picture, retrieved from the waste bin by a friend, which later won a gold medal in Munich. This perfectionism, coupled with his early death, account for the small volume of surviving work.
Exhibited RA (2), RSA (22), RSW (22), GI (8) & L (12), and is represented in the NGS, V & A, Glasgow AG, Kirkaldy AG and Newport AG.
