MUNDELEIN - Bernard M. "Barney" O'Connor, 86, passed away Friday, October 1, 2021, at his home. A Catholic Memorial Mass at Santa Maria del Popolo Chapel (116 N. Lake St., Mundelein) is scheduled for Saturday, October 23, 2021, at 9:30 AM and plans for a private interment ceremony at Mount Calvary Cemetery in Oxford, Iowa, is pending. Barney was born August 19, 1935, in Dyersville, Iowa, the son of Verni and Elva (Hansel) O'Connor. He married Jean Farmer on August 8, 1964. Barney was dedicated to his faith and his family. As a devout Catholic, he was commissioned as an Extraordinary Minister of Holy Communion to the Sick in the Archdiocese of Chicago. He enjoyed golf, bowling, watching game shows, and was a spectator of many sports. He was a proud grandfather; always cheering on his grandkids, as well as the Iowa Hawkeyes. He also spent his time with his church family and was very fond of his "M and M" group. Barney attended Loras College in Dubuque, Iowa and The University of Iowa in Iowa City, Iowa, where he earned his degrees in education. He received an Honorable Discharge from the U.S. Army where he served as a cryptographer. He continued on as a teacher and private tutor specializing in high school mathematics beginning in Oxford, Iowa, for the Clear Creek School District. After marrying Jean, they moved to Illinois, where he taught within the Mathematics Department at Glenbrook North High School in Northbrook, IL, where he retired in 1997. Barney is survived by his children; son, Michael (Tanya) O'Connor of Tiffin, Iowa; daughter, Kelly (Rob) O'Connor-Henderson of O'Fallon, Missouri; grandchildren, Lucas and Nicholas O'Connor and Robert and Kylie Henderson; a sister-in-law, Nancy O'Connor; along with nieces and nephews and their children, whom he loved and cared for dearly. The HDA will be greatly missed. He was preceded in death by his father in 1947; mother in 1980; his wife, Jean in 2010; and his brothers, Dr. Lowell O'Connor in 1975, Louis O'Connor in 2003, and Frank O'Connor in 2014, and a sister-in-law Darlene O'Connor in 2018. We would like to offer our appreciation to his neighbors and his church family for the care and faith you shared with our father. Memorials are preferred to the St. Francis Xavier Basilica in Dyersville, Iowa or Santa Maria del Popolo in Mundelein, Illinois.

Mike and Kelly you have my sincere sympathy. Berny was a great teacher. He will be missed. Always enjoyed talking to him when they were back in Iowa. I so miss Jean also. She used to babysit with me when she was in high school, and her family were our neighbors.

I would like to give a few thoughts on my friend and colleague Barney.
He loved his two families: in Mundelein with his wife and two children Mike and Kelly and later his grandchildren and his Dyersville family that he often talked about. He loved going to his family reunions in Dyersville and being with his family.

He loved teaching Mathematics and being able to help his students. He truely loved being around his fellow teachers at Glenbrook. He was always talking about "things" on our daily ride together.

He loved watching sports, especially baseball both in person and on TV.
He was always a supervisor at athletic events at Glenbrook for years.He didn't like some NY teams.

He loved to play golf and bowl. He always wanted to beat me whenever possible. He enjoyed his golf league on Sunday and his Friday night bowling league. He had many friends in both. In the old days he always enjoyed a beer or two after the leagues were over. His neighbors would often join him in his garage for a couple.

He was dedicated to the Catholic Church and his religion and it always gave him comfort. God has now found you so please have a good time.
