This is Thomas Michael Kettle – I don’t know who he is but I’m sure Wikipedia is clued in:
Extracted verbatim from Wikipedia:
Thomas Michael “Tom” Kettle (9 February 1880 – 9 September 1916) was an Irish journalist, barrister, writer, poet and economist. As nationalist, Home Rule politician and MP in the House of Commons of the United Kingdom of Great Britain and Ireland, he represented East Tyrone as member of the Irish Parliamentary Party from 1906-1910. He joined the Irish Volunteers in 1913, then on the outbreak of World War I in 1914 enlisted for service in an Irish regiment where in 1916 he met his death on the Western Front.
He was one of the leading figures of the generation who at the turn of the twentieth century gave new intellectual life to Irish party politics, and to the constitutional movement towards All-Ireland Home Rule. The Great War brought both of these and his life to an end. A gifted speaker with an incisive mind and devastating wit, his death was regarded as a great loss to Ireland’s political and intellectual life.
