A Chicago man who bought $1,000 worth of stock 70 years ago grew that money into millions, and has donated the money to create a wildlife sanctuary.

Russ Gremel, 98, never married and never had kids. He bought $1,000 worth of Walgreens stock decades ago, and kept it. Today, it's worth about $2 million, reported the Chicago Tribune.

Gremel donated the money to the Illinois Audubon Society. This weekend, the group dedicated the 400-acre Gremel Wildlife Sanctuary near Dixon, Illinois.

"You have to do some good in this world, that's what money is for," Gremel told the Tribune.
