Alan Bernard Dudkiewicz, 86, Green Bay, passed away peacefully on Saturday, May 2, 2026. He was born in Green Bay, on June 23, 1939 to the late Bernard Joseph Dudkiewicz and late Iris May (Vincent) Dudkiewicz.

Alan was born and raised in Green Bay, WI and graduated from Our Lady of Premontre High School that was known for its strong academic programs and community involvement. In 1989 Premontre closed and joined 2 other Green Bay Catholic schools in 1990 to form the current Notre Dame de la Baie Academy which continues to serve the community today. After high school graduation he served in the United States Army and was stationed at West Point Military Academy in New York where he met his beloved bride-to-be, Joyce, a West Point school teacher and the daughter of a West Point Army Major, Town Mayor, and more. Following his service, Alan married Joyce, the love of his life, in the sacrament of Holy Matrimony on September 2, 1961 in her home town of Highland Falls, New York. Their almost 65 years of marriage (64 years, 8 months exactly) is a testament to their faith, strong bond, love, commitment, and partnership. Together they had two cherished children, Christine and Brian.

Following his military service and becoming a husband, Alan resumed his goal of pursuing a degree in higher education. His strong work ethic, tenacity, intelligence, and Joyce's support were evident as he earned his Bachelor of Science in Biology at the University of Wisconsin, Stevens Point in only 3 years. Thereafter, his love for science, research, and academia, led him to the University of Massachusetts and to the University of Tennessee where he earned his Master of Science in Biology and his Ph. D. earning him the title Dr. Alan B. Dudkiewicz in academic circles. His success in academia provided him with the knowledge and skills needed to succeed in his professional career. Alan enjoyed work as much as he enjoyed life. Early in his career Alan did years of research resulting in hundreds of scientific journal publications for the University of Tennessee, the University of Georgia, and the University of Houston. One of his more significant achievements was his discovery of an oocyte (egg) enzyme and its method of action. This enzyme effectively prevented fertilization of the egg. During the midpoint of his career, he was recruited by a pioneering and driven doctor by the name of Dr. Gleicher who was located at Mt. Sinai Hospital in Chicago, Illinois and who had read his many publications and abstracts. Dr. Alan Dudkiewicz, Ph. D. was tasked with directing the Reproductive Medicine laboratory. Not only was he the High Complexity Clinical Laboratory Director and manager, his many colleagues over the years admired that he was always willing to "get his hands dirty" while performing not only the many important laboratory tasks, but also the various mundane lab tasks and routine equipment maintenance. Being in this role, Alan was seldom home with his family and was working or on-call 24 hours a day. One of his most significant achievements, as well as the city of Chicago's, was while working at Mt. Sinai Hospital, Alan was a central member of the medical team that celebrated the first live birth of a healthy human baby girl, Chloe, who began her life as an embryo outside the womb in the early 1980's! Chloe and the entire medical team made history because she was the first so called "test tube baby" or IVF baby in Chicago! Her parents prayed about having their own child but were experiencing significant infertility challenges, so they sought out this cutting edge medical treatment led by Dr. Gleicher. Nowadays, this infertility falls under the category of Reproductive Medicine, where IVF is just one subcategory. A fews years later, this OB/GYN doctor decided to leave the hospital to start his own practice bringing Alan and a few laboratory technologists with him. For the next 30+ years Dr. Dudkiewicz managed this new company's laboratory as a High Complexity Clinical Laboratory Director at The Center for Human Reproduction (CHR) in Chicago. During the final chapter of his career he worked for 12 years at the University of Chicago as the High Complexity Clinical Laboratory Director within the department of Reproductive Endocrinology and Fertility before retiring in 2016.

Alan also loved participating in sports throughout his life. Two sports in which he excelled were bowling and golf. He was an avid bowler and was actually the League Champion when he first met Joyce, who would become his wife. In fact, his first date with Joyce was a blind date on Friday the 13th and involved going bowling. Alan, being an extremely modest person, didn't tell Joyce how good of a bowler he actually was, and began to throw butterballs so she would feel more at ease. His teammates noticed this behavior and could not understand why their highest scoring bowler could not hit the pins. Well, you can imagine the look on Joyce's face when she noticed his picture on the wall of the bowling alley adjacent to the highest score! I'm sure they had many laughs over the years when reminiscing about this. Alan also enjoyed watching sports whenever possible and seldom missed a televised Green Bay Packers game.Regarding family, Alan loved spending time with his family, never missed an opportunity to teach a lesson, and enjoyed nature and being outdoors. He would go golfing, garden in his backyard, walk with Joyce, cook Thanksgiving feasts, and BBQ with family and friends. When it was time to leave no matter how old you were he would always say "let me know when you get home, and be careful." He enjoyed life to the fullest, set a proper example at all times, and his only worry was leaving Joyce. As some of you know, he tried to do everything physically possible even until the very end while in the hospital, before God called him home. His family reassured him that Joyce would be taken care of and asked him not to worry.

Above all, he loved God, Jesus Christ, and the Holy Spirit. He thoroughly enjoyed living his faith, being a lector and reading at Mass, volunteering with food deliveries, fundraising, and actively participating as a parishioner while belonging to many parishes during his life. After moving back to his hometown of Green Bay he attended daily mass at St. Elizabeth Ann Seton Catholic Church where he enjoyed his faith community and friendships with other parishioners. He is now at peace and in heaven with God.

Alan is survived by his wife Joyce (Rathke) Dudkiewicz, daughter Christine (Richard) Chan, granddaughter Emily Chan, brother Richard Dudkiewicz, sister Joanne Dudkiewicz, niece Kathryn Dudkiewicz, brother-in-law Francis Rathke, daughter-in-law Guadalupe Dudkiewicz Salgado, grandson Mario (Salina Payne) Montenegro, granddaughter Lissette Montenegro, and great-grandsons Jayden and Camden Montenegro.
