Dudley was part of a close knit working-class family. His father, Mesach, was an ironworker, employed at Bowen's ironworks in Bilston and his mother, Mary, was a coal-dealer's daughter from Ettingshall. He had three sisters Annie (b. 1882), Harriet (b. 1884) and Mary (b. 1894) and an older brother, Thomas (b. 1886)[2]
He studied at Bilston School of Art and later at the Royal College of Art, London, graduating from there in 1916.
The war years
During the First World War Dudley worked for the Intelligence Corps, drawing maps and he is mentioned in despatches for his bravery crawling through the trenches to deliver maps to the front line.[3] Some works from this period exist, including an etching of a monk and a watercolour of a young boy. At around this time he married Frances Wells, who had been his art teacher. The couple did not have children but they shared a love of art and were both keen travellers.
