Another bit of history to mark the day:

“Wear green on St. Patrick’s Day or get pinched.” That pretty much sums up the Irish-American “curriculum” that I learned when I was in school. Yes, I recall a nod to the so-called Potato Famine, but it was mentioned only in passing.
Sadly, today’s high school textbooks continue to largely ignore the famine, despite the fact that it was responsible for unimaginable suffering and the deaths of more than a million Irish peasants, and that it triggered the greatest wave of Irish immigration in U.S. history. Nor do textbooks make any attempt to help students link famines past and present.
