Jack Dean Seibold joined his wife of 68 years on Tuesday, May 8, 2018 at the age of 89. A long-time resident of Okemos, Michigan, Jack died in his sleep at home.

Jack was preceded in death by his wife, Dianne Seibold, his parents August and Hazel Seibold (Bell) and his brother Paul Seibold. Jack is survived by his brother Dave Seibold, his children, Bill and Laura Caudill (Seibold) of Muncie, Indiana, Greg and Jill Forman (Seibold) of Allen, Texas, and Lee and Carol Lantz (Seibold) of Lansing, Michigan; his grandchildren, Jeremy and Caitlin Lantz, Justin and Sharee Forman, Joshua and Michelle Cools (Lantz), Tyler and Jill Forman, Jason and Amanda Lantz, Ritchie and Sarah Caudill, Micah and Courtney Hedges (Forman), Aaron and Heather Johnson (Lantz), Karin Caudill, Brent and Abigail Voorhees (Forman), Stephan and Jennifer Lantz, and Jonathan Lantz; step-grandchildren, Ryan Caudill and Aaron Caudill and 23 great-grandchildren.

Jack was born at home on September 10, 1928, in Jackson, Michigan. Growing up, summers included reveling in boyhood adventures with his brothers at the cottage on Clark Lake. Jack graduated from Jackson High School in 1946 as student body president and earned a bachelor’s degree in journalism at Michigan State College.

Jack met his soul mate, Dianne Helgeson Seibold, while lifeguarding at Oakland Hills Country Club. They were married on July 28, 1950, at St. Paul’s Cathedral in Detroit. Together they created a loving home full of treasured memories. During their years together, they enjoyed traveling, cheering for the Spartans, and most importantly, spending time with family. Cherished family trips were taken to their Ocean Village condo in Florida and the fishing cabin in Canada. Jack was an incredible grandpa who loved creating special moments. His grandchildren will always treasure memories of his magic tricks, trivia games, “the doors”, stashes of goodies, and his generous heart. Known as Majack, he created traditions that will endure.

Though he worked at Ferris State University during his early years, the focus of his career was at his alma mater as Associate Director of Admissions and Scholarships. For over 30 years, Jack helped a myriad of students, shared his passion for MSU, gained a reputation as an engaging speaker, and developed a circle of friends that continued until his passing. As a 4-year letter winner and avid supporter of Spartan athletics, Jack served the MSU Varsity Alumni Club for 22 years, helped coordinate the Save Our Sparty project, attended Spartan football games since 1950 and wrote the book Spartan Sports Encyclopedia.

Swimming was a family affair for Jack. He swam competitively with his two brothers at Jackson High School and Michigan State College. His devotion to MSU swimming remained until his death as he spent countless years officiating meets and presenting the Golden Spike Award at the annual swimming banquets. In addition, he founded and coached the Okemos Aquatic Club, an age-group swimming team which not only provided opportunity for youth to hone their skills but also forged a community of life-long friendships.

Jack also cultivated an extensive group of loyal friends through the Turkey softball team and fishing trips. Since 1970 Jack eagerly looked forward to the annual fishing expedition to Ile Paradis in Ontario, where he served as camp cook and entertainer. In the Canadian wilderness, fishing stories were exchanged, friendships were deepened, and memories were forever imprinted. Though Jack will be greatly missed, his indelible mark will remain on the lives of his daughters, grandchildren, great grandchildren, and friends. We will always remember his laugh, wit, fun-loving spirit, and abundant generosity.

The funeral will take place Friday, May 11, 2018 at Williamston Free Methodist Church, 4400 N. Williamston Road, at 10:00 am. The family will accept friends Thursday, May 10, 2018 from 6-8 p.m. at Gorsline Runciman Funeral Homes East Lansing Chapel, 1730 E. Grand River Ave., East Lansing, and again one hour prior to the service at the church.

I just found out about the passing of your dear father. What a blessing it was to know him. He gave countless hours of service to the swimming community. He was such a positive force. He is an example for all of us. Laura and Jill, your father was such a supportive person. Thank you for the lovely video.

Take Care and God Bless.

Thank you Grandpa for the happiness and smiles you always shared. No matter the situation you always managed to find something to laugh about and make people smile. I'll never forget the Christmas candy, cars full of presents, Ma Jack shows and surprise drawers full of ways you wanted to bless us. We truly love you and we're thankful to call you Grandpa.

Since graduating from Michigan State in 1950, Grandpa Jack attended all but 3 Michigan State home football games. Once to officiate a swim meet, which should indicate his commitment to the sport, and twice for medical reasons. That's 68 years of season tickets.

This is just one of the stories I tell people when I say green and white "runs in my blood."

This is a picture of my last game with him, the second last of his 68 year run. Our Spartans upset Penn State 27-24.

I spent a lot of time thinking about how to honor my Grandpa, what stories I might tell, but I settled on simply this: I'm grateful.

I'm grateful because my Grandpa had a big impact on my life. Not just in the experiences and support he gave but in shaping who I became through his example.

I'm grateful because my Grandpa loved to laugh, and he taught me to love it too. Laughter and wit were a big part of who he was. As a grandson this was infectious, and I always wanted to make him smile. I’m a little jealous of my cousin Ritchie who made him laugh with ease, but the two of them taught me how to join the fun.

I'm grateful because my Grandpa taught me to be generous and make friends wherever I go. One year as we were leaving the fishing cabin, Grandpa was packing up filets to give the train conductor. I asked why, and he said, “Always be generous to someone picking you up in the wilderness.” That wasn't the first time he made friends with the conductor. He always did that. What I hadn't realized is that he wasn't giving filets to an old buddy, he was making a purposeful choice to be generous.

I'm also grateful to be a Spartan. Not because I'm an alumnus. I'm not. Not because I grew up here. Not because of our sports program. I'm a Spartan because of my Grandpa. As a kid my cousins and I wandered Spartan Stadium, found shelter in the varsity club, and even played football on the field. To me being a Spartan isn’t about being a fan. It's about family. I will never hear the MSU shadows without thinking of Grandpa.

Last of all, I'm grateful Grandpa knew my kids. The last two years they spent a lot of time with him, and once while feeling discouraged about his health he said, "There's something about the next generation that makes it all worth it." Later it became his tradition to buzz my daughter around on an electric cart at Meijer and buy her doughnuts. Just as he treated me when I was a child. He had started the cycle all over again.

For all that I am grateful.

Some people know others everywhere they go. Gramps would often be interrupted by someone calling out “hey Jack!” Eventually we’d be on our way and he would confess, “I have no idea who that was.”

Grandpa may not have known everyone, but he did make everyone feel known. He took time to get to know their names, find out something about them, and make a mark on their lives that would not soon be forgotten. This happened thousands, if not tens of thousands of times in his lifetime.

Grandpa was also very stubborn. That stubbornness was demonstrated most notably in his tenacious generosity. No matter what we said, there was always too much food at dinner, more than enough Christmas gifts, and some kind of trip in mind for the grandkids.

This same stubbornness kept grandpa going for years after his body was already failing. He was not about to leave his bride while she needed him, and he wanted to give us as much as he could one this earth, demonstrating Philippians 1:21-25.

Grandpa also put together a 1072 page book. I watched him spend countless hours gathering stories and pouring over microfilm. In the end he argued his byline didn’t need to be on it. It was never about him. It was about the people he loved. The story of his heart and his life is you. He lived his life for you, for your progress and joy in the faith.

We can honor Gramps today by continuing that story. Follow in his footsteps. Discover the unconditional love of Jesus Christ that he did, then learn to love each person you meet--in the stadium, in the grocery store, and on the way somewhere--as if he or she is the most important thing of that moment.

In the words of the Apostle Paul in 2 Timothy 4, Grandpa has fought the good fight, he has finished his race, and he is now receiving a crown of righteousness in heaven where he can be beside his bride once more.

Thank you Gramps for everything. You will be missed, and we will always love you.

Grandpa was a master at creating memories. He had a way of making even the simplest things in life special. He made ordinary things extraordinary. Some of the things I will miss the most are the comfort and warmth I experienced just by walking through the doors of their home, the tenderness and faithfulness of his care for Grandma, the attention he took to really, truly listen to me, the way he laughed, and laughed easily, the humility and desire he had to learn and grow and change until the very end, the way he collected friends everywhere he went because of his genuine love for and interest in people, the amazing Majack shows, trivia and name the face games, the special treats tailored to whoever was in town, “the doors” and grab bags that convinced me that our family Christmas was the best in the world. My life is different because of Grandpa in so many ways. I will find ways to make simple things abound with significance and tradition. I will seek to model his humility and love for learning, I will try to make people feel loved and important wherever I go, and truly hear their stories. I will seek to put first things first, to cherish my faith and my family as he did.

Gramps, I couldn’t be prouder to be your granddaughter. Thank you for being such a giant presence in my life. I will miss you every single day, and long for heaven all the more. I love you!

A Spartan lives a life of discipline and self denial. You are our Spartan, my Spartan!! I’m proud that a fraction of that runs through my veins. On this earth you played your hand the best. Serving everyone around you to the very end. I love you grandpa, you have no idea how much your influence has shaped my life. I see you in myself more and more each day, and thanks for the thick head of hair! I’ll be with you again one day and we will take that Ocean Village Mulligan, Love you dearly!

Grandpa Jack,
I am so glad I got to spend some time, here on earth, with you! You impressed on me gentleness, kindness, loyalty and love. It’s easy to see how so many were drawn to you. Though I didn’t go to MSU it seems almost everyone else in my family did and therefore I have a hint of that spartan pride engrained in me from childhood. Ever since Ty and I have been together a state flag has been hanging. When I see it now I’m reminded of you and therefore reminded to portray gentleness, kindness, loyalty and love. Thanks for that, it makes me a better person. Looking forward to more conversations in heaven; until then, keep an eye on us, we’ll make ya proud!

Grandpa Jack was a man that no one forgot. He had a way of leaving an impression on people, even those he had just met. His way with words, his jokes, and his consistent kindness and generosity made you feel like the most important person in the world. Grandpa made it his personal goal to make sure no one was left out and everyone was always having fun.

Grandpa even made an impression with his collections. He collected baseball memorabilia that I'll always remember hanging in his home. He collected front row seats to MSU football games. But most importantly, he was a collector of memories. He was always up for another adventure. He not only collected memories for himself, but he made sure every one one of his grandkids had their own collection of memories, too. From extravagant Thanksmas, up to Canada, down to Florida, from one grandkid's sporting event to another's recital, Grandpa was always there to make it memorable for us. He was always there to leave an impression.

But the greatest impression Grandpa left was the one he made on our family. In everything Grandpa orchestrated - jokes, toasts, magic shows, Jeopardy games - his goal was to create a family that loved one another and knew the value of being together. I can picture all of us sitting around his living room, laughing and yelling as we try to "place the face," truly enjoying one another's company. Grandpa was always there to support us in our personal endeavors, even if they were of no interest to him. I think he knew that in showing up for each of us, we would learn to show up for each other. Grandpa demonstrated to each of us what family is. I see that impression live on in his daughter's families, and the families of all his grandchildren.

Thanks Gramps, for all the memories you collected for us, for teaching us even when we didn't realize it, and for always leaving an impression. We love you and miss you dearly.
