Mary Elizabeth DiEmedio (nee Lynn) peacefully passed away on September 21, 2025, at her home in Glen Mills, PA, after a brave battle with glioblastoma. Born on July 19, 1964, in Allentown, PA, Mary was raised in Bethlehem, where she cherished the love of her family and nurtured her passion for learning. A proud 1982 graduate of Southern Lehigh High School, Mary went on to earn her bachelor's degrees in industrial engineering and general arts and sciences from Penn State University. Throughout her exceptional career, Mary dedicated over 25 years to the aerospace industry, most notably with The Boeing Company, where her contributions as a systems engineer left a lasting impact. She also worked at the Navy Ship Yard in Philadelphia, exemplifying her commitment to her vocation and country. Mary's spirit shone bright in her personal life, where she balanced her professional achievements with a deep love for her family, friends, and a multitude of hobbies. From playing the piano and spending summers in Ocean City, New Jersey, to camping, hiking, sewing, and enjoying movie nights, Mary's zest for life inspired those around her. She delighted in meaningful conversations with friends and, above all, treasured the time spent with her beloved family. Mary is survived by her cherished children, Lauren Aker (Andrew), Caroline Anderson, and David Anderson, her loving parents, John and Nancy Chamberlain Lynn, her siblings, John Lynn (Beth) and Karen Darentiere (Louis), as well as her brother, Michael Lynn (Kathleen), who preceded her in death. Mary is also survived by the father of her children Edwin Anderson. She leaves behind a wonderful legacy, including numerous nieces, nephews, extended family, and very special friends whose lives she touched.
