A well-known American artist who visited Polperro in 1940. He was born in San Francisco but completed his education in Scotland, living with his widowed grandmother in Kirkcaldy. After leaving school, he studied art at Heatherley's and at Lambeth Art Schools in London.

His career in journalism took him to New York and subsequently to South Africa, where he covered the Boer War. Returning to the USA, he carried out illustrations alongside his painting practice. An early success as a marine artist was a watercolour of the ship US Constitution, the original of which is owned by the White House.

After World War I, he exhibited his marine paintings at the National Academy of Design and the American Watercolor Society. He was also a highly regarded etcher, winning a number of prizes at the Chicago Society of Etchers.

Grant's painting of Polperro which is dated 1940 was shown at the Allied Artists of America exhibition in 1943 and won the 'Anonymous Member's Prize'.

During his time in Cornwall it is suggested that he may have visited Falmouth and Mousehole.
