COUNCIL BLUFFS, Iowa (AP) — A former schoolteacher has left her $2.5 million estate to the Council Bluffs Public Library Foundation.

Ann Cook died Dec. 16, 2012. She was 70.

Cook was a Council Bluffs resident who taught school across the Missouri River in Omaha from 1964 to 1997. After retirement she volunteered more time to the Friends of the Library organization.

Library Foundation President Steve Krohn says the money will help the organization’s efforts to supplement book collections, fund various programs and buy new technology.

Cook’s attorney, Gary Faust, is a member of the foundation board, too. He says Cook “had a great deal of love for the library. She wanted to see it continue to prosper.”

Faust says Cook inherited much of her wealth and lived frugally.
