Ann Marie Ritter was born in Waterloo, N.Y., and raised in Seneca Falls, N.Y., where she graduated in 1978 from Mynderse Academy High School.
She earned a bachelor's degree in English from the State University of New York in Geneseo in 1982 and a master's degree in higher education from Walden University, an online university, this year.
During the 1980s, she worked as a ranger at the Women's Rights National Historical Park in Seneca Falls.
Mrs. Rayner later moved to Baltimore. For the last 10 years, she had been director of academic initiatives for institutional quality and integrity at Laureate Education Inc., a Baltimore-based higher education company. She held that position until being diagnosed with brain cancer earlier this year.
The Timonium resident enjoyed listening to music, attending the theater, reading and going to the movies. She also was a cat fancier and baker and an accomplished needle pointer.
She also liked visiting the Finger Lakes region of upstate New York.
Services will be held at 11 a.m. Saturday at the First Presbyterian Church in Seneca Falls.
