Peter Frederick Briscoe Snow (1927–2008) was an English painter, theatre designer and teacher. From the 1960s to the 1990s he was head of postgraduate theatre design at the Slade School of Fine Art, with the help of Nicholas Georgiadis and later, Yolanda Sonnabend.
Peter Snow, son of Sir Frederick Snow, was educated at Bloxham School in Oxfordshire, where he showed an early talent for painting and was involved in designing sets for school plays. In 1946, he studied briefly at Goldsmiths College and worked as a journalist on the South London Press before doing his national service with the Royal Engineers in the Middle East. Following his time in the army he gained a scholarship to the Slade, studying until 1953 and joining the staff in 1957. He was head of theatre design, succeeding Robert Medley.
Snow started working in theatre in 1951, when he designed Love's Labour's Lost for the Southwark Shakespeare Festival. In 1954, Snow worked alongside Joan Littlewood at her Theatre Workshop in Stratford East. Two of his most admired designs for Littlewood were for a revival of John Marston's The Dutch Courtesan. Other early theatre work included designs for Lennox Berkeley's one-act opera A Dinner Engagement at the Aldeburgh Festival in 1954, Frederick Ashton's ballet Variations on a Theme by Purcell at the Royal Opera House in 1955, and Noël Coward's South Sea Bubble, at the Lyric Theatre in 1956. In 1955, Snow designed the British premiere of Samuel Beckett's Waiting for Godot, directed by Peter Hall at the Arts Theatre, where he also designed the costumes.
