Marie A. Hogan-Sullivan, 81, of Wallingford, who taught social studies at Chester High School for more than 30 years, died of cancer Sunday at home.
Mrs. Hogan-Sullivan graduated from Notre Dame High School in Moylan and earned a bachelor's degree from Chestnut Hill College. She studied in Greece on a Fulbright scholarship and earned a master's degree in social studies from the University of Pennsylvania.
She worked for the CIA in Washington for a year, and for the FBI in Philadelphia for another year before becoming a teacher in the Chester-Upland School District. She taught elementary students for a short time before joining the Chester High staff.
She often stayed after school to help students, including one who was blind, said her husband, Joseph A. Sullivan. Since retiring in 1991, she was greeted often by grateful students when she was shopping, and sometimes even when she visited China, he said.
For many years, Mrs. Hogan-Sullivan cared for an aunt and uncle and her mother. Though she and her husband met in the 1970s, they waited to marry until after her mother's death in 1992.
Mrs. Hogan-Sullivan was a member of the World Affairs Council and St. John Chrysostom Church in Wallingford.
In addition to her husband, she is survived by cousins.
A Funeral Mass will be said at 10:30 a.m. today at St. Katharine Drexel Church, 1020 Providence Ave., Chester. Friends may call from 9 a.m. Burial will be in SS. Peter and Paul Cemetery, Marple Township.
