She lived much of her life in New York City luxury, but Mary Griggs Burke never forgot her Minnesota roots.

Museums around the world courted her, hoping she would bequeath to them her legendary collection of Japanese art, but it was to the Minneapolis Institute of Arts that she left the bulk of it: 700 pieces of rare Japanese and Korean art, spanning 5,000 years, along with a $12.5 million endowment.

The bequest from Burke, announced Monday, catapults the Minneapolis museum’s Japanese collection into the top tier of U.S. museums.
