Librarian revealed to have $4 million fortune, leaves to university he worked at for 50 years

(INSIDE EDITION) - When a modest librarian at the University of New Hampshire passed away last year at 77 years old, no one expected he would have accumulated more than $4 million in his lifetime, or what he would do with it.

The late Robert Morin donated every penny of his fortune to his alma mater, where he worked for nearly 50 years.

"He never went out," Morin's financial adviser Edward Mullen said in an interview with Union Leader. Morin apparently drove an older car, ate frozen dinners and never spent any money.

His retirement account alone had nearly $1 million in it.

According to Mullen, he wanted to leave all the money to the school to help future students.

In a statement Tuesday, UNH announced the generous former employee surprised the school with a $4 million gift.

"Bob's demonstrated commitment to UNH through his philanthropy is tremendously inspiring," UNH President Mark Huddleston said, according to the statement.

Of the donation, Morin specified $100,000 to be donated to the school's Dimond Library where he worked until retirement in 2014 as a facility librarian.

The rest of the money will be spent on a new video scoreboard for the football stadium and a career center for students and alumni.

"We are committed to providing the resources needed to ensure every student achieves professional success and Bob's gift will play a major role in that effort," Huddleston said.
