Francis Archibald Wentworth Walter, self-styled 7th Prince of the West Indies, Lord of Follies and the Ding-a-Ding Nook, was born in Antigua in 1926. He was prodigiously talented as both a writer and artist, but his undeniable genius was flawed by delusions of aristocratic grandeur, namely a belief that the white slave owners in his ancestry linked him to the noble houses of Europe, from Charles II to Franz Joseph of Austria and the Dukes of Buccleuch. As a young man, aged just 22 in 1948, Walter tasted success as the first man of colour to manage an Antiguan sugar plantation, but although hugely revered on the island for his intellect and achievements he left it all behind to tour Europe in pursuit of new skills and his own increasingly convoluted genealogical meanderings. A visit to Scotland in the early 1950s marked the beginnings of a life-long affection for a country to which he repeatedly returned in his imagination and in his paintings.

Walter’s remarkable gifts were the product of a fertile, but fragile, mind and having returned to the Caribbean he spent the last twenty five years of his life in an isolated shack on an Antiguan hillside, surrounded by his writings, some 25,000 closely-typed pages of history, philosophy and autobiography, and by the extraordinary paintings and carvings that speak with such an unmistakable and visionary voice. These paintings range in subject from miniature landscapes, many of them Scottish; to abstract explorations of nuclear energy; to portraits, both real and imagined, including Hitler playing cricket and Charles and Diana as Adam and Eve. Painted with a rare immediacy, on whatever material came to hand, they announce the discovery of one of the most intriguing and distinctive Caribbean artists of the last 50 years.

Walter's work was exhibited alongside paintings by Alfred Wallis and Forrest Bess in the exhibition Songs of Innocence and Experience at Ingleby Gallery in Spring 2013. A solo exhibition of his work was presented by The Douglas Hyde Gallery, Trinity College, Dublin in Summer 2013 and later that year, Ingleby Gallery presented a solo display of Walter's paintings and his hillside shack at Art Basel Miami Beach. A major solo exhibition followed at Ingleby Gallery in spring 2015.
In 2017, Frank Walter represented Antigua and Barbuda at the Venice Bienniale, in a show called Frank Walter:  The Last Universal Man 1926–2009. A solo presentation of Walter's work also took place at Harewood House, Leeds, UK in the summer of 2017.
