By 1850, Courtauld employed over 2,000 people in his three silk mills, and he had recruited partners including (in 1828) his brother, George Courtauld II (1802–1861) and (in 1849) fellow Unitarian social reformer Peter Alfred Taylor (1819-1891 – son of Peter Taylor who died the following year). By this time, Courtauld was a wealthy man but was also suffering from deafness. He had planned to spend more time on his country estate Gosfield Hall near Halstead, but continued to play an active role in the company until just before he died in March 1881.
