Paper offers proof of ‘No Irish need apply’ ads

That was challenged by a prominent American historian who dismissed widespread anti-Irish discrimination as a legend fostered by cultural imagination and ignorance.
According to Richard Jensen, former professor of history at the University of Illinois in Chicago, the so-called NINA ads barely existed — if at all. In a 2002 article in the Oxford Journal of Social History entitled: “‘No Irish Need Apply’: A Myth of Victimisation” Jensen claimed the signs were a fabricated memory of Irish-Americans to make themselves appear as victims.
