Robert Clayton Quinlan

June 12, 1930 - December 21, 2023

With heavy hearts, we announce the passing of Robert Clayton Quinlan, a beloved husband, father, teacher, and friend.

Born on June 12, 1930, in San Francisco to Albert and Eula Quinlan, Robert’s educational journey led him through Lawton Grade School, Lincoln High School, City College, San Jose State University, and San Francisco State, earning Bachelor’s and Master’s degrees in English and journalism.

Robert proudly served in the US Army from 195254, stationed primarily at Fort Ord. He was an avid San Francisco Giants fan during his youth, college, and military leaves. He sold cushions at Seal Stadium and later Candlestick Park, supporting his education and nurturing his unwavering passion for the team. One of his greatest joys was witnessing the San Francisco Giants’ historic victory in the 2010 World Series in person, surrounded by his beloved wife, Mary, and their children. Throughout his life, he deeply loved and respected his brother, Richard Quinlan, cherishing their bond and shared memories.

Robert was a dedicated educator who impacted his students, earning them respect and gratitude. He married fellow English teacher Mary McKnight and enjoyed 58 joyful years together. Their sons, Thomas McKnight Quinlan and David Geoffrey Quinlan, and grandchildren, Chase and Blake, brought immeasurable happiness to their lives. Mary and Robert traveled the world, reveling in adventures documented with engaging stories, vivid pictures, and treasured memories.

Robert also found great joy in coaching Little League baseball, with his teams winning 11 championships in Hillsborough/San Mateo. Family gatherings filled with friendly competition, discussing grammar intricacies during dinner, and cherished summers spent in Maui. In his favorite moments, Robert and Mary would relax in their backyard, savoring cocktails while watching their boys play water basketball under the setting sun’s golden glow, with the barbecue heating.

A celebration of life for Robert will be held on January 13th, 2 p.m. at The Episcopal Church of St. Matthew, at 1 South El Camino Real, San Mateo, Calif. 94401. Contributions may be made in his memory to the Alzheimer’s & Dementia Association at www.alz.org.
