WICHITA FALLS, Texas (AP) Elizabeth Perkins Prothro, philanthropist and longtime benefactor of Southern Methodist University, has died at her Wichita Falls home. She was 89.

Prothro's death Saturday was announced in a news release from Graham Public Relations and a statement from SMU, where the Perkins School of Theology bears her family's name. Her parents were founding contributors to the Dallas university in 1913, and in the early 1940s endowed the theology school.

"Elizabeth Prothro has left an indelible mark on SMU and on all who knew her," SMU President R. Gerald Turner said in a written statement.

The Perkins and Prothro families and their foundations have given more than $36.3 million to SMU.
