Resided in Naperville, Illinois


John “Jack” Holland Hennessey Jr., age 78 of Naperville, IL died October 2, 2020 after a long brave battle with Alzheimer’s Disease.
Jack was born November 7, 1941 in Providence, RI to John and Dorothy Hennessey. He graduated from Colt Memorial High School in 1960, where at one time he held the record for basketball rebounds in a season. After graduation, he attended classes at the University of Rhode Island for a year and served in the U.S. Army. In 1968, he began his career in earnest at Modern Drop Forge in Blue Island, IL where he tirelessly worked for 32 years. At Modern, as he did in life, he lived by the motto of “helping people”, quietly and without fanfare. Whether it was helping a struggling unemployed neighbor with a job, getting treatment for an employee battling addiction or successfully fighting with an insurance company to get employees the benefits they paid for, he was always looking out for others. Superman to some, husband, father, grandpa, and friend to others, his character was demonstrated by the way he treated people that could do nothing for him.
As a testament to his fortitude & dedication while working at Modern, he attended Loyola University night school to complete his bachelor’s degree and then master’s degree, all while helping to raise his family. In 2005, Jack began his second career as an Aviation Host for Southwest Airlines where he thoroughly enjoyed the people he met during his travels.
Jack lived for 18 years in Homewood, IL where he was active within the community managing several Little League & Babe Ruth championship teams. His love of children was exemplified in his coaching and later while volunteering for the CASA organization, where he served as a vocal and ardent court-appointed special advocate for children in foster care. Always looking to offer a guiding hand, his volunteerism later continued with St. Vincent de Paul in St. Augustine, FL. Jack enjoyed playing tennis, running, biking, competing in everything, reading, history, and travel. He especially enjoyed the outdoors and the beach was his heaven on earth. In 2016, Jack was one of the many die-hard Chicago Cub fans to celebrate their World Series Championship.
Jack is survived by his wife Bonnie, sons Byron (Lorraine), Brendan, Matt (Betsy), and Steve (Sharifa), daughter Bridget and 8 grandchildren, Carolyn, Alex, Kevin, Halle, Jennifer, Nori, JHH3, and Hailey, along with cousins, friends, and 2 dogs. He was preceded in death by his parents, younger sister, Maj. Susan M. Hennessey (USAF, Ret.) and grandparents, Roydon May & Harriet (Butterfield) Wardwell and James & Susie (Coughlin) Hennessey.
Memorial Services will be held on Thursday, October 15th at Holy Spirit Catholic Community Church in Naperville, IL at 11:00AM. Burial services will be the following day at Memorial Park Cemetery in Skokie, IL. In lieu of flowers the Hennessey family wishes memorial donations to be sent to the Alzheimer’s Association.
