Ronald Alfred Lee (1913-2000) was the youngest son of the dealer Henry Morton Lee ( see H.M. Lee & Sons). Ronald Lee initially joined the family business in 1931, but set up his own antique business just after the Second World War, initially at 36 Grena Road, Richmond in 1946, and then at 1 The Terrace, Richmond Hill in 1949, before moving the business to Ormeley Lodge, Twickenham, in 1952 - the former home of the Duchess of Argyll in the late 17th century. In the 1960s R.A. Lee was joined in the business by his brother Charles (d.1998), and moved the business to Bruton Place, London. The collector and former Managing Director of Woolworths, Reginald Thomas Gwynn (known as Peter Gwynn) joined the business in the 1960s. Georgina Gough (nee Lee) the daughter of R.A. Lee, joined the firm in 1976.
The business merged into Asprey & Co in the 1990s.
R.A. Lee was a leading authority of English clocks (see R.A. Lee The Knibb Family - Clockmakers (1965)). Ronald was elected president of the BADA in 1956.
