Diane F. Nockles, 93, beloved mother, friend, teacher, and traveler, passed away peacefully on Nov. 26, 2025.
Born in October 1932 in Boston, Diane grew up with an innate desire to explore, to learn, and to share what she discovered with others. This calling naturally led her to her life’s work as an educator. For over 30 years, she taught and led with uncommon patience and enthusiasm, inspiring countless students not only to master their lessons but to believe in themselves.
A traveler at heart, Diane found joy in discovering new landscapes, cultures, and stories. Whether she was wandering through historic cities, driving through the country’s national parks or simply meeting new people on her journeys, she embraced the world with openness and gratitude. She was also a proud New England Patriots fan, cheering faithfully through every season, celebrating victories, and standing loyal through the tough games.
She is survived by her daughter who will carry forward her spirit of compassion, learning, and adventure. She is preceded in death by her parents.
To know Diane was to witness a life lived with purpose and heart. She will be profoundly missed and forever remembered.

Diane was such a warm presence in our childrens’ lives and ours! She helped define Lincoln for us when we were new to town. We are grateful for her gifts of positiveness and inclusion and good will.
Our family is grateful for Diane’s work with our son in elementary school. Seeing her later at Bemis Hall she always asked how he was doing. All those years later she remembered and cared. Then one day, I visited with my grandson and Diane was so happy to meet the next generation of one of her beloved students. She welcomed him with genuine interest and affection. In those early years of instruction for my son, she planted seeds that are still thriving. I will miss seeing her. Mary Ann Hales
