Growing up in the 1960s and '70s, the five McNulty kids never knew who might be at their dinner table from one night to the next.
Their mom, Helen McNulty, a Spanish teacher and student adviser at the University of Minnesota, loved to invite foreign students into their home.
"She really opened our eyes that there was more to the world than our street in Minneapolis," said son Tim McNulty.
She even took the whole family — all five kids and husband Bob McNulty (a sports arena developer and one of the original owners of the Minnesota North Stars hockey team) — on study-abroad adventures while she worked as an adviser to the Student Project for Amity Among Nations program.
"She and my father had a sit-down, and she said, 'Lets take the family,' " said Tim McNulty.
They spent months living in Peru and Ireland while she worked as a student adviser, he said.
Helen McNulty died Jan. 4 at age 97.
She was born in Minneapolis, the oldest of six.
