Pritchett's father was a steady Christian Scientist but unsteady in all else. Walter and Beatrice moved to Ipswich to be near her sister, who had married money and lived in Warrington Road. Within a year Walter was declared bankrupt, the family moved to Woodford, Essex, then to Derby and he began selling women's clothing and accessories as a travelling salesman. Pritchett was soon sent with his brother Cyril to live with their paternal grandparents in Sedbergh, where the boys attended their first school. Walter's business failures, his casual attitude to credit and his easy deceitfulness obliged the family to move frequently. The family was reunited, but life was always precarious. They tended to live in London suburbs with members of Beatrice's family, but returned to Ipswich in 1910 to live for a year near Cauldwell Hall Road, trying to evade Walter's creditors. At this time Pritchett attended St John's School. Subsequently, the family moved to East Dulwich and he attended Alleyn's School, but when his paternal grandparents came to live with them at age 16, he was forced to leave school to work as a clerk and leather buyer in Bermondsey. At the same time his father enlisted to work in Hampshire at an aircraft factory to help the war effort. After the Great War Walter turned his hand to aircraft design, about which he knew nothing, and his later ventures included art needlework, property speculation and faith healing.
