Cornelius “Neil” Francis Delaney Sr., professor of philosophy emeritus at the University of Notre Dame, died in his sleep on Saturday, Oct. 18. He was 87.
Originally from Waterbury, Connecticut, Delaney was born to Irish immigrant parents. His father passed away when he was young, and he worked at a local pharmacy to help support his family. He initially entered the seminary after graduating high school, but left and began to focus on philosophy.
Delaney received his bachelor’s degree from St. John’s College in New York, his master’s in philosophy from Boston College, and his doctorate from Saint Louis University. He then joined the Notre Dame philosophy faculty, where he served for more than 50 years and held leadership positions, including department chair, director of the Notre Dame London program, and director of what is now known as the Glynn Family Honors Program for nearly 25 years.
“No one played a bigger role in the growth of Notre Dame's philosophy department than Neil,” said Jeff Speaks, professor of philosophy and former chair of the department. “He chaired the department from 1971 until 1982 and, not coincidentally, this was the period in which our philosophy department became a nationally and internationally recognized department.”
Delaney’s research was grounded in pragmatism and focused on political philosophy, legal philosophy, and the history of modern philosophy. He published more than 50 academic articles in various journals, as well as writing and editing several scholarly books. He was also very active in connecting with students, often encouraging and celebrating their accomplishments.
“We had a wonderful time discussing a variety of subjects, from novels to modern art to University politics, to which he himself made tremendous contributions,” said Paul Weithman, the Glynn Family Honors Professor of Philosophy, whose office was next to Delaney’s for a time. “He was a great source of advice when I was department chair, and he built up what became the Glynn Family Honors Program, where I had the good fortune to succeed him as co-director. Neil was a mentor and friend to whom I was tremendously indebted.”
During his tenure at Notre Dame, Delaney’s impact on students and faculty led to him winning virtually every major award the College of Arts & Letters and University conferred — he received the Madden Award for Teaching in 1974, the Emily Schossberger Award in 1983, the President’s Award in 1984, the Sheedy Award for Excellence in Teaching in 1987, the Kaneb Teaching Award in 2001, and a faculty award in 2005.
“Philosophers can be boring; Neil was not,” Speaks said. “He was a great conversationalist, quick-witted, funny, and had a wide-ranging intellect. He was as at home talking about art or literature or Notre Dame football as about philosophy. He was the backbone of the department for decades and will be sorely missed.”
Delaney is preceded in death by his wife, Helen, and his son, Neil Jr. He is survived by his grandson, Prescott Spenser Delaney. He will be buried in a private ceremony at Notre Dame’s Cedar Grove Cemetery. A memorial Mass, open to the public, will be held at 3:30 p.m. Thursday, Nov. 6, at the Basilica of the Sacred Heart.
