Percy Johnson-Marshall studied at the Liverpool School of Architecture at the University of Liverpool, where his brother Stirrat Johnson-Marshall was already a student, from 1931-1938. He initially completed a Diploma in Architecture and afterwards the Certificate in Civic Design. While a student Johnson-Marshall studied under a number of brilliant professorships. When he started his studies, the professor of architecture was Sir Charles Herbert Reilly who was followed by Lionel Bailey Budden in 1933. Meanwhile Sir Leslie Patrick Abercrombie was the professor of civic design until 1935 and it is likely that Johnson-Marshall studied under him. Johnson-Marshall was a very able student, and during his time in Liverpool he won a number of awards, including the John Lewis Partnership Prize, 1936 and the HW Williams Prize for the Promotion of Architectural Design in Concrete, also in 1936. His education at the University of Liverpool had a lasting influence over both his style and future career. After leaving the University, Percy Johnson-Marshall, along with other former students, instigated the formation of the Liverpool School of Architecture Society, a club for former students. After a successful inauguration dinner, this appears to have had a short life.
