Robert L. Sierer

We are sad to announce the death of Robert L. (Bob, Bobby, Coach, UBob, Gramps, The Geezer) Sierer, aged 90, who died on December 4, 2024, in Wilmington, DE. Bob is survived by his daughters Libby Craig of The Woodlands, TX, Patricia Hensey of Wilmington, DE, Susan Sobocinski and husband Rick of Newark, DE; step-son Chuck Haupt and wife Mary of Owego, NY, step-daughter Linda Haupt of Fort Collins, CO; grandchildren Ryan Craig, Taylor Craig, Kelsey Moragas, Larn Hensey, Shannon Fortmann, Nicholas Sobocinski and Samantha Sobocinski, and 5 great grandchildren. He is predeceased by his first wife Leda Erdman Sierer, and second wife Josephine Haupt Sierer.

Bobby was one of 9 children from Wiconisco, PA where, as a teen, he played many sports, but distinguished himself at Lykens High School in football, and went on to play at Bucknell University. The “Lykens Lightning” married his high school sweetheart Leda after college and moved to Wilmington where Bob became a teacher and the head football coach at A.I. DuPont High School, a position he held for 20 years. Coach Sierer had many successful seasons, conference championships, and successfully coached the underdog Blues to a win over the favored Golds in the 1968 All-Star game. He led the A.I. ski team, assisted with wrestling, and could also be found on the back of a donkey playing basketball for charity. Coach believed that athletics develop the total person to become all that he is capable of, and teaches lessons in citizenship and democracy, and also having fun! He was a favorite teacher and later in life would run into former students all over the country.

Eventually, UBob moved to Goldey Beacom College where he ran an economic development program, assisted with foreign students studying in the U.S., and secured money for the college’s endowment and programs. His favorite role remained interacting with students. UBob was an avid reader, writer, orator and Uno Card player, and as UBob morphed into Gramps, he applied all of these skills to schooling his grandchildren in the ways of the world, talking to them about his life lessons and pushing them to think deeper about themselves. Sometimes that meant cheating at Uno, embellishing a story or speaking in PA Dutch.

After retiring and the death of his first wife, Gramps moved to Maine and married Jaye Haupt. Families were blended, new and old friends mingled – a 70-year-old man married an 80-year-old woman, and for 18 years those in their orbit enjoyed the benefits of being a part of The Geezer’s world. Port Clyde Baptist Church, Marshall Point Lighthouse and Bartlett Woods all embraced the Geezer as he embraced them. He liked to “think deep,” in the words of his step-daughter, and he generated many writings on history, theology, family and love – often on the backs of napkins and decorated with a Kilroy, (IYKYK!). But he could also b.s. with the best of them, make you laugh till you cried, or challenge you to really think, so you never knew what was coming. Though he lived far from his family in the later years of his life, they never questioned his love for them and how much they were cherished. Each of his daughters thought they were his favorite! The following was taken from a newsletter piece he wrote a few years ago:

“All things are transient on this earth, be it power, glory, wealth, and even entire civilizations. All we can do is put all our love into our lives and into our families, making a work of art of the few precious years that are granted to us. This is the lesson I learned as a young boy, and I hope to leave some meaningful recollections to my children and grandchildren. My hope is that each of us will leave a few specks of dust in our family attics.”

Bob left everyone with a very dusty attic. He is very much missed.

Funeral Services

Services will be private for immediate family only. The family would like to thank the 3rd Floor Healthcare Staff at Foulk Living for the love, care and compassion they provided to Bob and his family. They would also like to thank the staff at Vitas Healthcare Hospice for their endless support, guidance and comfort. Both groups are angels on earth.

    Outside of my family, Coach was the biggest influence on my life. He taught us about democracy, our Republic and the Constituion in high school. He coached our football team to an undefeated season in 1964. Years passed. I visited Jaye and him in Maine, toured the lighthouse they supported and bought him a lobster roll at his favorite shop. Years passed. With Linda Haupt’s help and good wishes, we found him in Wilmington and visited him there. Throughout this incredible life, he taught respect for our greatest institutions, hard work and joy in every endeavor. Such a full life. Will I miss him? Yes. Will I remember him? Forever.

    I joined the Marshall Point Lighthouse & Museum Committee when Bob was Chairman. I got to know he and Jaye well over the years and under his steady hand, their love for the Lighthouse and Museum was very evident. Today and 3 Committe Chairs later, MPLH&LM is strong, and doing well, thanks to the leadership and dedication of people like Bob over the years. "Fair winds and following seas" He will be missed.

    This is sad. Coach coached my brother Bob in the 1968 All Star game, my brother Dave through an incredible 1970 season at AI and me as a sophomore at AI. I continued to see him until he moved to Maine. I credit him for helping develop my discipline in life. This is sad but brings back great memories.

    I’m so sad to hear that one of the best fatherly coaches I had a A I DuPont HS in football has passed. He was not only a true great coach but also a great teacher and man to look up to as a kid growing up. He will never be forgotten for all his contributions to bringing the best out in his students and players. Coach Sierer will always be a great memory and was a great part of my growing up as a man

    I was privileged to play for Coach Sierer and be instructed by him in his history class. He had a very significant influence on my life and many others. He had the ability to inspire enormous respect along with a little fear when it was needed. I guess I can now admit that I was the one who messed up the Geronimo drill. Rest in peace Coach; your memory will live on with those of us who were privileged to know you.

    So sorry for your loss. I had the privilege of playing on 3 of coach Sierer's football teams at AI, including the 1964 team. Not only did he give us the tools to win, but more importantly in the other years he taught us never to give up in a game or in season. We learned much about football from him but most of all we learned so many life lessons on the field and the classroom that I carry still. He will be missed and always remembered by all those he touched.

    I spent two years in class with Mr. Sierer, 1965/66 I was part of a class called Contemporary Affairs. Imagine a class in which the textbook was the New York Times, to which we were required to subscribe. Then in 1966/67, I was in his US History class. It was my first taste of genuine academic learning. The tests always started "In a brief yet concise essay explain the significant aspects of...." And he gave us the single final exam question at least a week in advance: "What then is this new man, the American?" '

    It was a privilege to have Coach Sierer as a teacher, coach and mentor. I arrived at A. I. in grade 10. The transition was unpleasant and a personal struggle. Coach Sierer presented a stabilizing influence and for that I am thankful. Our teams may not have had an abundance of talent but Coach Sierer did instill in us a sound work ethic and a good grasp of the fundamentals. You will be missed. Rest in Peace Coach.

    I had the pleasure of working with Bob when I was a junior staffer at the Delaware State Chamber of Commerce 45+ years ago to promote the programs of the Americans for a Competitive Enterprise System (ACES) for which he was executive director while at Goldey Beacom. He focused on training high school teachers to incorporate economics into their lesson plans. The program involved visits with business leaders and tours of companies all over the state…and each year he had a new class of teachers with a specially designed t-shirt. It was fun seeing the photo of Bob holding a t-shirt because he was always excited when the new t-shirts arrived! He brought great enthusiasm and commitment to his mission - and he made a meaningful difference. It is nice to see he had a long life with a great family. My prayers are that the sadness of his passing will be replaced by warm memories. Keep the faith. Blake Wilson, Pasadena, MD

    I had Bob Sierer as a teacher for US History and Contemporary Affairs in the '60's. I remember that we studied part of Beard's An Economic Interpretation of the US Constitution. This was pretty heady stuff at that age especially for teenagers with hormones not overly oriented to sophisticated economic analysis. He was a truly great teacher and his impact on me and my classmates continues to this day. He will be missed.

    Bob was a teacher and coach of mine while attending AI. He helped instill a desire in me to always try and do better no matter what my success or failure was. I regret I never told him how much of a positive influence he had on my life. It has been over 50 years but I can still remember his famous quote on the football practice field no matter how tired you were "let's do it one more time"
