Born Betty Christine Xenakis in Clarksburg, W.Va., and raised in nearby Weston, she earned a Bachelor of Science degree at the Carnegie Institute of Technology.
She moved to Baltimore to live with her sister and taught home economics at Kenwood High School and later at Stemmers Run Junior High School. She also taught at Overlea High School and retired from Chesapeake High School.
A resident of Perry Hall for nearly 50 years, Mrs. Jackovitz was a past president of the Women's Club of Perry Hall. She also belonged to the Perry Hall Improvement Association and worked to have a pair of community identification signs installed at Belair and Joppa roads.
Family members said she enjoyed cooking. She was a volunteer at Greek Orthodox Cathedral of the Annunciation's annual Greek Festival and contributed to a church cookbook.
"She was the consummate homemaker and opened her home and served dinners from appetizers to desserts," said her daughter, Kathie M. Harrington of New York City. "She kept a binder of menus of every party she planned."
Services will be held at 11 a.m. Friday at the Greek Orthodox Cathedral of the Annunciation, 24 W. Preston St.
In addition to her daughter, survivors include her husband of 56 years, Edward F. Jackovitz, also a retired Baltimore County teacher; a son, Stephen M. Jackovitz of Bel Air; another daughter, Christie A. Williams of Towson; a sister, Alexandra X. Lygoumenos of Timonium; and seven grandchildren.
