(AP) – The widow of a man who became a successful geologist has donated $1 million to the University of Kansas.

The university announced the gift Tuesday from Kathleen Hall of Lecompton. She and her husband, Hubert Hall, both earned bachelor’s degrees from Kansas in 1949. She says several other members of Hubert Hall’s family attended the university.

The gift will establish the Hubert H. and Kathleen M. Hall Professorship in Geology. The donation is intended for a mid-career faculty member or an incoming professor.

Hub Hall worked for Standard Oil, now ExxonMobil, and led the company’s exploration around the world. He and his wife retired to Kansas in 1986, and he died in 2010.

The Halls have made several other donations to the university.
