Dannatt, was introduced to the world of photography thanks to his father’s interest in the subject. He began exploring photography when he was 14 years of age and seemed to enjoy clicking pictures that focused on form. It has to be noted that George’s interest in photography began before the introduction of roll film which helped develop observation skills and attention to details.

George had developed an interest in music right from his school years and continued to pursue music studies for many years. He was said to have been deeply influenced after hearing the Piano Concerto for the Left Hand performed by Paul Wittgenstein in 1932. In addition to the private piano lessons, Dannatt began studying composition and harmony at Blackheath Conservatoire during evenings even as he continued working as a surveyor. Previous to his tenure with Army, Dannatt focused on songwriting. He wrote 11 songs between 1939 and 1947. After his return from the army, he focused on working as a music critic for News Chronicle from 1944-1956.

Dannatt worked on abstract paintings using the influence from Dorset and Wilshire landscape to create the base of his artworks. During the initial years, he worked using gouache, later moving to oils and then to other experimental mediums. He experimented with collage and three-dimensional constructions as well and appeared to lean in favour of geometrical painting.
