Obituary of Peter Anthony O'Brien, Jr.

Please share a memory of Peter to include in a keepsake book for family and friends.


Peter A. O’Brien, Jr., 94, died on January 3, 2023 at his home in Jenkintown, PA.


Peter was born June 19, 1928 in Newark, NJ and grew up in Hasbrouck Heights.  As a young teen he moved with his family to East Orange and attended East Orange HS where he met and fell in love with the girl who would become his wife, Marie J. McCarroll (d.1986).  They were married on October 28, 1950.  They lived for over 30 years in Birchwood Village, Rockaway Twp. and had 9 children.


Peter received his undergraduate and graduate degrees from Rutgers University and his PhD in Economics from Walden University.  After working for a bank clearing house early in his career, he turned to teaching and was a Professor of Economics at Pace University NYC Campus for close to 40 years, retiring in 1997.  In 1998 he married Margaret (Peggy) B. Allan (nee Mullen).  A second marriage for them both, they made their home in Lyndhurst NJ and enjoyed traveling and being with their growing families until her passing in 2011.


A student of the Civil War, there was almost nothing he couldn’t tell you about the where, when, and why of that period.  He refrained from collecting memorabilia but, rather, was a collector of knowledge and could converse for hours on the subject.  He loved to travel, with he and Marie taking their kids camping across the U.S. and Canada.  When he finally conceded that they weren’t going to build a bridge to Ireland, Peggy B. finally convinced him to fly, and they enjoyed several trips there together as well as trips to Mexico, Scotland, Canada and the U.S. He loved being with his grandchildren and great grandchildren, watching them play and grow and especially holding the babies.


Peter was predeceased by his wife Marie and their son, Daniel Gerard (d. 1965).  He was also predeceased by his wife Peggy B.  He is survived by his 8 children: Mary E. Shortridge (David), Rock Hill SC; Peter A. O’Brien, III (Peggy), Exeter, NH; Ellen O’Brien-Drexel (Robert), NJ; James J. O’Brien (Cherie’), Alexandria, VA; Margaret A. Hart (Christopher), Mirror Lake, NH; Catherine J. O’Brien, White Plains, NY; Thomas M. O’Brien (Amie), Bay Village, OH; Robert F.X. O’Brien (Jeffrey Brady), Wyncote, PA: 12 grandchildren: Mary Beth Salomone-Testa (Jack), Anthony Salomone (Angelique), Jeffrey O’Brien, Kara Sullivan (Sean), Zachary George (Erika), Darren George, Austin O’Brien, Conor O’Brien, Sean O’Brien, Daniel Hart (Sarah), Mollie LaBelle (Josh), Samuel Hart (Brittany): 12 great grandchildren: Lucas Testa, Juliet Salomone, Garrett Salomone, Catherine Sullivan, Cora Sullivan, Edwin Sullivan, Walter George, Henry George, Owen Hart, Carson Hart, Rylee LaBelle, Benjamin LaBelle and great grandchild #13, expected in January 2023, as well as several nieces and nephews.


The family suggests a contribution to St. Jude Children’s Research Hospital in lieu of flowers.
