Landers died Sept. 14 at her home in El Dorado, Ark., at age 93.
She made her first trip to Haiti in 1977, accompanying her late husband, Gardner, an ophthalmologist, on a medical mission trip. Together, they made more than 20 medical mission trips to the country. While there, she met Father Jean Wilfrid Albert, an Episcopal priest who told her of the many Haitian children living in poverty without access to education, and introduced her to some of the children.
Returning home, Landers began raising money to provide schools for the children, speaking at churches and to civic groups throughout the region and helping to provide funding to build schools in the mountains of southern Haiti.
The Haiti Education Foundation now supports 40 schools serving about 9,000 students.
Landers, a member of First Church in El Dorado, is survived by her three sons and their wives; her grandchildren and great-grandchildren.
A memorial service will be held at 11 a.m. Sept. 23 at First Church in El Dorado. Memorial gifts may be sent to: the Haiti Education Foundation, c/o First Presbyterian Church, 300 E. Main St., El Dorado, AR 71730.
