Dadbeh Bigonahy, 85, of Worcester, passed away peacefully on October 12, 2026, at Rose Monahan, surrounded by his loving family.
He leaves behind his beloved wife, Nasrin Bigonahy; his daughter, Mishana Tsoutsis; his son, Zhubin Bigonahy; his cherished grandchildren, Darian and Mina Tsoutsis, whom he adored; and his sisters, Fahimeh, Farideh, and Fereshteh.
He was predeceased by his parents, Abos and Batool Bigonahy, and his sister, Farah.
Born in Mashad, Iran, on January 4, 1941, Dadbeh lived a life defined by dedication, generosity, and an unwavering commitment to education and family. After serving in the military in Iran, he met his beloved wife, Nasrin, and together they immigrated to the United States in 1971 to begin a new chapter of their lives. Shortly thereafter, they started their family, building a life rooted in love, hard work, and the pursuit of knowledge.
Dadbeh went on to earn his Master's Degree in Mechanical Engineering from Worcester Polytechnic Institute (WPI), beginning a distinguished career in higher education that would become one of his greatest passions. He started teaching part-time at Quinsigamond Community College (QCC) and eventually became a full-time professor and coordinator of Engineering and Biomedical Engineering. He later earned the distinction of Professor Emeritus at QCC.
A lifelong learner, Dadbeh devoted countless years to research in pursuit of his Ph.D. in Biomedical Engineering, a goal he worked tirelessly toward. His passion for learning was matched only by his desire to help others succeed. Throughout his career, he went above and beyond for his students, helping them secure scholarships and opportunities at Ivy League schools and some of the nation's top universities. To Dadbeh, teaching was more than a profession; it was a calling. He believed in the potential of his students and dedicated his life to helping them achieve things they may never have imagined possible.
His influence will live on in the many students whose lives and futures he helped shape.
As accomplished as he was professionally, Dadbeh's greatest joy was his family. He was a devoted husband, a loving father, and an adoring grandfather. There was little he would not do for those he loved. Whether picking up his grandchildren from school, driving them to their many activities, or patiently teaching them math and science, he was always there, giving his time, sharing his knowledge, and showing his love in countless ways. His grandchildren, Darian and Mina, brought him immeasurable joy, and he cherished every moment spent with them.
Dadbeh was also known for his kindness, generosity, and thoughtful spirit. One of his sweetest traditions was giving orchids to everyone he knew, even when he knew full well that many of them struggled to keep the flowers alive! It was a simple but unmistakable expression of who he was: a man who loved to give, who thought of others, and who found happiness in bringing a little beauty into their lives. Those orchids, like his many acts of kindness, will remain a lasting reminder of his generous heart.
Dadbeh's legacy is one of knowledge shared, opportunities created, and love freely given. He leaves behind generations of students whose lives he influenced, a family who was the center of his world, and countless memories that will continue to bring comfort and smiles to those who knew him. His wisdom, generosity, and devotion will never be forgotten. Though he will be deeply missed, the lessons he taught, the lives he touched, and the love he gave will endure.
His visitation is Saturday, October 17th in O’CONNOR BROTHERS FUNERAL HOME, 592 Park Avenue from 2:00 until 4:00 p.m. In lieu of flowers memorial contributions may be made to cancer research at Massachusetts General Hospital in Boston in Dadbeh’s memory.
