History
The firm's origins date back to 1898 when Nathaniel Reynolds partnered with Alexander Arnold Hannay to establish Hannay & Reynolds. Following their separation, Reynolds launched his own practice on the Strand, London, in 1903. His son Hugh joined three years later, prompting a rebranding to Reynolds & Son. In 1919, David Reynolds became part of the firm, which was then renamed Reynolds & Sons. Gerald Thomas Gorst entered the partnership in 1926. Over subsequent decades, the firm operated under various titles including Reynolds Sons & Gorst, Reynolds & Gorst, and Reynolds, Gorst & Porter until 1962. It was renamed Reynolds Porter & Taylor Jelf that year before adopting Reynolds Porter & Co in 1963.
Chamberlain & Co was founded by Walter John Chamberlain after his admission in 1906. Initially practising solo in Croydon, he established Chamberlain & Co at Lincoln's Inn, London in 1907. Walter held public offices including Mayor of Croydon (1927–1929) and Clerk of the Fine Art Trade Guild. His son Francis Walter Chamberlain joined after World War I and later received a CBE while serving as Justice of the Peace and Deputy Lord Lieutenant.
In 1971, these two firms united to create Reynolds Porter Chamberlain & Co; approximately ten years later, the "& Co" suffix was removed.
