WICHITA FALLS, Texas - Elizabeth Perkins Prothro, a philanthropist and longtime benefactor of Southern Methodist University, has died. She was 89.

Prothro died at her Wichita Falls home Saturday, according to 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.

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

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