Bulmer Hobson
John Bulmer Hobson (1883–1969) was a leading member of the Irish Volunteers and the Irish Republican Brotherhood (IRB) before the Easter Rising in 1916. Though he was a member of the organisation that planned the Rising, he was opposed to it being carried out, and attempted to prevent it.
He is also notable for swearing Patrick Pearse into the IRB in late 1913.
