The Manistee, Michigan, community is mourning the death of Ryan Francis O’Donnell, a longtime high school chemistry teacher whose career in education spanned more than two decades. O’Donnell, 50, died on Sunday, August 23, 2026. Born on September 29, 1975, Ryan was the son of William and Carol (Boes) O’Donnell. He grew up in Brighton, Michigan, as the youngest of five children, surrounded by an extended family that included grandparents, aunts, uncles and cousins. From an early age, Ryan developed a curiosity about the world around him. His family remembered him drawing detailed scenes and maps, spending time outdoors with his siblings and dogs, watching war documentaries with his father and enjoying the company of the family cats. Ryan O’Donnell’s Education and Career Ryan attended Michigan State University, graduating in 1998 with a degree in chemical engineering. His professional path eventually led him into education. After relocating to Manistee, he returned to school at Ferris State University, earning a master’s degree in education. He went on to become a high school chemistry teacher and spent more than 20 years helping students discover an interest in science. Ryan took particular pride in seeing his former students succeed. His obituary notes that he was especially pleased when former students returned to tell him that his chemistry classes had prepared them well for college or careers involving chemistry. His enthusiasm for teaching was evident outside the classroom as well. In Manistee, he was known for leading demonstrations in which his Advanced Placement chemistry students introduced younger children to scientific concepts through hands-on experiments. A Teacher Who Made Science Come Alive Ryan’s influence reached well beyond his own classroom. Students under his direction participated in demonstrations for elementary school children, showing them experiments involving chemical reactions, dry ice and other scientific phenomena. For Ryan, teaching was more than simply explaining formulas and laboratory procedures. He wanted students to understand the world around them and appreciate the science behind everyday experiences. His former students and the wider Manistee educational community will remember the enthusiasm he brought to his work and the pride he took in watching young people develop their own interests and abilities. Ryan O’Donnell Family and Personal Life Ryan married Blythe (Fickes) O’Donnell in November 1999. The couple had known each other since high school and maintained their relationship while attending different colleges before eventually building their life together in northern Michigan. Ryan and Blythe raised four children: Brynn, Jack, Andy and Maeve. Family was central to Ryan’s life. He attended his children’s games, concerts, recitals, athletic meets and theatrical performances and supported them throughout their childhood. He also enjoyed introducing his children to the natural world. According to his family tribute, Ryan taught them about insects, trees, animal tracks, the night sky and weather. He had a particular interest in storms and snow prediction and shared his love of fly fishing with his family. He was also known for his interest in geography and was always ready with a question about maps or the world around them. Remembering Ryan O’Donnell Although Ryan was deeply committed to teaching and science, his family remembered him above all for the love he showed the people closest to him. Those who knew him understood that he had strong views about politics, faith and even the question of whether additional seasoning belonged in a recipe. Beneath those familiar characteristics, however, was a man whose family knew they were loved. His death has left his wife, children, mother, siblings and extended family facing a profound bereavement. Ryan is survived by his wife, Blythe; his four children, Brynn, Jack, Andy and Maeve; his mother; his sister Anne-Marie Wiley and her husband, Jon; his brothers Tim, Will and Fred and their spouses; as well as numerous nieces, nephews, aunts, uncles and cousins. His death is also being felt by the many students he taught during more than two decades in the classroom. For a teacher, a legacy is often measured not only by years of service but by the people who remember what they learned and how they were encouraged. Ryan’s influence will continue through those former students and through the lessons he shared with his own children. Funeral Arrangements for Ryan O’Donnell A Mass from the Order of Christian Funerals is scheduled for Thursday, August 27, 2026, at 11:00 a.m. at Guardian Angel Catholic Church in Manistee, Michigan.

At 50, Ryan leaves behind a life marked by curiosity, dedication and service. His classroom may no longer have his familiar presence, but the knowledge he shared and the lives he influenced will remain part of his enduring legacy.
