Sir Edmund Grimani Hornby (29 May 1825 – 17 November 1896) was a leading Jewish-Italian British judge, with family interests in diamond-rich Antwerp. He was the founder and Chief Judge of both the British Supreme Consular Court at Constantinople and British Supreme Court for China and Japan. (Hornby had a nephew, Edmund Hornby Grimani, who also had a career in China with the Chinese Maritime Customs. The two should not be confused).
