Seago was born in Norwich on 31st March 1910, to a family of Coal Merchants. He attended Norwich School, and never received any formal artistic training. He taught himself to paint, although received advice from the acclaimed equestrian painter Alfred Munnings. The boy’s talent was quickly noticed, and he won a prize for drawing at the age of 14 from the Royal Drawing Society.
English artist, Edward Seago mostly painted oils and watercolours, travelling widely during his life starting from the 1930s. As a young artist, Seago was fascinated (like Munnings and Dame Laura Knight) by the Circus and the life of travellers. He joined the circus in his younger years as he was also interested in the stage and ballet but in time his love of pure landscape took priority. Through his travels in the circus, he went on to visit Northern France, Holland, Portugal, Hong Kong, Antarctica and Africa.
