Sir Thomas Graham Jackson, 1st Baronet RA (21 December 1835 – 7 November 1924) was one of the most distinguished British architects of his generation.

[1] Much of his career was devoted to the architecture of education, and he worked extensively for various schools, notably Giggleswick and his own alma mater Brighton College.

Jackson was a prolific author of carefully researched works in architectural history, often illustrated with sketches made during his extensive travels.

It remains today a fundamental source of knowledge of the geography, art, architecture and social life of Dalmatia in those years.

The other concentrated group of mural tablets by Jackson is to be found in the antechapel of Wadham College in Oxford.
