LOUISVILLE, Ky. (WDRB) -- The Louisville Chapter of the American Red Cross received its largest donation ever, prompted by a tragic accident. 

Board members and supporters dedicated the Red Cross Emergency Operations Center to Jack and Gladys Jonas on Tuesday.

Their estate gift of $1.4 million is meant to help the Red Cross respond to weather-related disasters.

A family tragedy led to the Jonas' donation.

"Their nephew Cark was injured in a farming accident and lost his arm," said Jennifer Adrio, CEO of Kentucky Region. "And as they were re-attaching it, they used several products from the Red Cross so the Jonases, in particular Jack, became a significant donor to the Red Cross."

The Red Cross can't budget for disasters since they're not planned, so the gift will allow it to help in emergencies without having to raise additional money.
