TOPEKA — Washburn University is describing a $6 million gift as the largest in its history.

The Topeka school said in a news release Friday that the money comes from Jacki Summerson and her late husband, Frank. The money has been placed in an irrevocable trust. Ultimately, it will be used to pay for high-caliber faculty members.

The Summersons received undergraduate degrees from Washburn University in the late 1960s. His was in business administration; hers was in mathematics and physical sciences.
