On the death of the head of the firm and the consequent dissolution of partnership, Richard Green continued the business in conjunction with his then surviving brother Henry.

His favourite saying was that "he had no time to hesitate", and he was noteworthy for his unfailing promptitude, quick decision, clear judgment, and great business acumen.

He died near Regent's Park on 17 Jan. 1863, and his funeral at Trinity Independent Chapel, Poplar (founded by his father), was attended by an immense concourse.

Green left by his will a large number of charitable bequests, including a free gift of the building and a perpetual endowment of his Sailors' Home at Poplar.

A statue by Edward William Wyon (1811–1885), of Green stands outside the Poplar Baths, his face modeled from his death mask; with him is his faithful Newfoundland dog "Hector".
