James Edmund Vincent was a barrister and journalist. He married Mary Alexandra Cook in 1884.
Vincent was first called to the Bar in 1884 and practiced on the North Welsh circuit. Around this time he also commenced his literary career, publishing on a variety of political and social topics, especially land reform in Wales (such as Tenancy in Wales, 1887). He soon abandoned law for journalism and became a staff reporter (and later special correspondent) for the London Times in 1886.
He also published a number of works of biography and topography including a Life of the Duke of Clarence (1893) and From Cradle to Crown (1902), a popular biography of Edward VII. From 1894-1897 he was editor of the National Observer, and it ws in this role that he was in correspondence with Whistler. This was followed by a stint as editor of Country Life from 1897 to 1901.
