Sir Edwin Arney Speed (11 March 1869 – 14 December 1941) was the Chief Justice of Nigeria from 1914 to 1918. He was highly thought of by Lord Lugard who secured his appointment as the Chief Justice of the amalgamated Southern and Northern protectorates. He was tasked by Lugard to unify the laws of the two colonies and to establish a single Supreme, Provincial and Native court system.[1]
