Mary Ann Brockman Jones, 87, also known as Mary Ann Brockman, died at her home in Princeton on Saturday morning, October 17, 2015 after a long battle with ovarian cancer.

She was born August 30, 1928 in Princeton, NJ, the daughter of the late George C. Knaefler and Karen Theilgard Knaefler. She graduated from Princeton High School with honors and earned a BA degree from Case Western Reserve University with a double major in mathematics and sociology. In her early years she was a computer programmer working on problems in the fields of mathematics, physics, and engineering. In her late 40s she received a master's degree in psychology from the Graduate Faculty of the New School for Social Research. She is a life member of Mensa and the Royal Scottish Country Dance Society.

In 1953 she married Dr. Karl W. Brockman, Jr, a physicist at Princeton University. In 1957 they moved to Amsterdam, The Netherlands where her husband did research in nuclear and particle physics at the Institute for Nuclear Physics and guided Amsterdam University doctoral students in their research. They had six idyllic years there until her husband's untimely death from melanoma in 1963.

She traveled extensively throughout most of Europe and the former Soviet Union. She was an enthusiastic photographer with several hundred published photographs in books and magazines.

She loved reading and had many interests throughout her life including the fine arts and music, literature, history, science, and medicine. She loved her computer and could spend hours on it, marveling that she didn't need to go to the library to research any topic. An interest in politics began during the buildup to the Iraq War, which she opposed. During the years she lived in the Netherlands she saw how well universal healthcare and social services worked as a safety net for everyone.

She is survived by her beloved second husband of 38 years, Dudley M Jones, who has been her primary caregiver and was with her till the end, and her large extended family, all of whom she loved dearly.

A Memorial Service will be held on Saturday, November 21, 2015 beginning at Noon at University Chapel, Princeton University, Princeton, NJ, with a committal service to follow at Princeton Cemetery, Princeton, NJ

In lieu of flowers donations may be made to American Cancer Society, 2600 U.S. 1, North Brunswick Township, NJ 08902 (donate.cancer.org), for research in ovarian cancer and other hormonal cancers.
