Leaving Oxford, and arriving in London, Gore trained at the Slade under Henry Tonks and at the Westminster School of Art with Mark Gertler and Polunin from whom he learnt the flat-on-the-floor method of painting backdrops for the theatre: most useful later on when as an active member of the Balalaika Dance Group as dancer and organiser of events, he enhanced their productions with his professional expertise.
Pre-World War II, his career took off when a Greek patron saw his work and asked him to spend a year travelling and painting in Greece.
Visits and extended sojourns to France followed, and an exhibition at Gallery Borghese in Paris in 1938 when Vauxelles called him the English fauve.
[4] His students and colleagues there included many of the most accomplished artists of the twentieth century who continue to acknowledge the encouragement they received from Gore.
[6] His published books include "Abstract Art",[7] "Painting: Some Basic Principles"[8] and "The Baptism, Piero della Francesca";[9] he is also the author of an unpublished translation of poems by Baudelaire.
