The Dayton Foundation has received $3.3 million from the combined estates of Dorothea “Dottie” and Donald Spindler of Kettering for the Donald M. and Dorothea Hunt Spindler Endowment Fund.

The gift represents one of the largest gifts in the foundation’s 88-year history.

Dottie Spindler worked as the secretary to the president of Third National Bank, now KeyBank NA, for 38 years. She died in May 2002 at the age of 89.

Donald Spindler, a World War II Army Air Corps veteran and longtime Dayton Power and Light Company employee, died in February 2007 at 95. They lived in Kettering.

Their endowment fund will benefit 15 local charitable organizations and support the foundation’s community leadership initiatives and its competitive grant-making program. Through this program, the foundation can help address needs and opportunities in the community.

“The Dayton Foundation is honored to be entrusted with this generous gift,” Michael M. Parks, the foundation’s president, said in a news release. “It not only represents the Spindlers’ trust in The Dayton Foundation to carry out their hopes and dreams for the community, but also their belief in the future of the greater Dayton region.”
