A big thank you to fiscallyfitchica for letting me know about this wonderful Surprise Millionaire!
Robert “Bob” Morin spent nearly fifty years working as a cataloger for the University of New Hampshire library while quietly accumulating a vast amount of wealth. 
Mr. Morin was obviously a no frills kind of guy as evidenced in the news article below but led a very busy life:
“Morin wasn’t a big spender, but he kept busy. UNH said Morin was passionate about movies, and watched more than 22,000 videos from 1979 to 1997. He also read every book published in America between 1930 and 1940, excluding children’s books, textbooks and books about cooking and technology, UNH said.”
By living frugally and investing wisely, Mr. Morin was able to leave a $4 million estate to the university that he loved. The funds will be used to enhance the campus career center and a host of other projects. Let’s hope Mr. Morin’s example inspires others to live frugally, invest wisely and bless others with the results!
