C. Arthur Cassell

November 30, 1927 ‒ August 14, 2020

Mount Vernon, Ohio

C. Arthur “Art” Cassell, age 92, of Mount Vernon, Ohio, passed away on Friday, August 14, 2020 at Country Court Nursing Home. He was born on November 30, 1927 in Mount Vernon, Ohio the son of Charles Howard and Alice (Campbell) Cassell.

Art graduated from Mount Vernon High School in 1945.  After graduating he served in the United States Navy from 1946 to 1948.  Upon leaving the military he attended Michigan State University (class of 1951.) and earned his Master’s degrees from the Ohio State University (1954) and the State University of New York at Buffalo (1966.)

Art taught mathematics at Mount Vernon for 30 years where he chaired the math department for most of those years.  He also taught in Worthington OH, Central Ohio Technical College and the Ohio State University.  As a teacher, he was known for his dry sense of humor and his love of inflicting word problems on his algebra students.  In his later years, hu very much enjoyed attending high school reunions for his class and subsequent classes, especially when he could catch up with former students.

Art operated Cassell Angus Farm with help from his wife Joan and sons Jeff, Brian and Alan, from 1969-1999, being the fifth generation to do so and continued to take great pride in watching his grandsons the seventh generation, currently operating on the family farm.

He was an active member of First Congregational United Church of Christ since 1937 where he was active in the choir and other church functions.

Art sold tickets to Mount Vernon High School athletic events for 56 years, and for four years at both Michigan State University and Worthington High School.  He loved music including playing the organ and singing in the church choir.  He was active in the Heart of Ohio Angus Association and enjoyed playing bridge with a regular group of friends.  Although Art volunteered much of his time to help others, there was nothing he loved more than the quality time he spent with his family.  He always made it a point to attend any event or function that his children and grandchildren participated in.

He was preceded in death by his parents, his wife Joan Morin Cassell whom he married in 1954, and their infant son Douglas Cassell.  Art passed away on what would have been the 66th year anniversary of his marriage to Joan.

Art is survived by three sons Jeffrey (Terri) Cassell and Alan (Traci) Cassell of Mount Vernon and Brian (Linda) Cassell of Bozeman, Montana.

He is also survived by four grandchildren: Grant (Lindsey) Cassell of Mount Vernon, Carter (Shelby) Cassell of Westerville, Dr. Emily Cassell of Columbus, and Michelle (Jason) McDonald of Houston, TX and great grandchildren Connor, Levi and Adelynn McDonald, Gavin Springston; a sister, Jean Slinkman of Bemidji, MN and a brother in law, Capt. Gene (Betty) Morin of Greenville, South Carolina.

The family will observe a private burial in Mound View Cemetery with a Celebration of Life service to be held at the church at a later date.  The Flowers-Snyder Funeral Home of Mount Vernon is honored to serve the family of C. Arthur “Art” Cassell.

Memorial contributions in Art’s name may be made to Hospice of Knox County, 17700 Coshocton Ave., Mount Vernon, Ohio 43050 or Interchurch Social Services, 306 W. Gambier Street, Mount Vernon, Ohio 43050.

  • I enjoyed talking with Art. I admired his deep senses of devotion and love for his wife and his children and grandchildren. I also appreciated his wonderful sense of humor and, of course, his dedication to teaching in our community. Art was a very good man and a blessing. He will be missed very much. My heartfelt condolences and prayers for his family.

  • Art was one of my favorite teachers in high school….his dry sense of humor was a big part of his personality and served him well dealing with students of all abilities…I enjoyed Art as he was a courier for the Bank for a number of years and his wit always brought a smile to many of our employees…..he always threatened to bring my math transcripts into the bank ( I wasn’t an A student, but still enjoyed his classes)….he leaves behind a family of which he should and would be proud of…my condolences to those he leaves behind.

  • The Cassell family,

    We are sorry for the loss of your loved one. Our heart goes out to you at this difficult time. Just know you are in our thoughts and prayers for peace and comfort in the days ahead

  • My heart goes out to all of you. Mr Cassell(because I would never call him by his first name) lived a great life. He gave me the background in math to follow his footsteps. We enjoyed chatting at volleyball games in more recent years. That dry sense of humor and sly smile will always be remembered! Prayers for you!

  • Mt Cassell was a great man and a teacher, he made math fun. But beyond teaching he was there to mold all his kids and students to become better people as adults. My sorrow filled heart goes out to the entire Cassell Family and all the people he touch in his life.

  • Sorry for your family’s loss. Praying you find comfort in all the great memories you shared. Mr. Cassell (I could never call him Art) was one of the best teachers! I don’t know how he made Honors Math fun but he did! I attended a few Yellow Jackets games with my parents,MANY years after I graduated from MVHS, and loved seeing him! He will be remembered as a remarkable man who touched SO MANY lives! God Bless!

  • I am so very sorry for the loss of Art! I enjoyed seeing him every year at Thanksgiving and talking with him. So wonderful that he, and now the boys, are keeping the family farm and legacy continuing on! I am thinking of you all and praying over you..(((hugs)))

  • For many years we were neighbors and thoroughly enjoyed Art’s visits and his sense of humor. Art was a very kind and caring gentleman.

  • Our deepest condolences to your entire family. His example of a beautiful life well lived did not go unnoticed and there’s great testimony that he’s now receiving his beautiful and well deserved reward in Glory!
    With love,

  • Jeff and Terri and the Cassell family,

    Morgan and I are so very sorry for your loss. We are thankful for Art’s beautiful life, his wonderful family, and we are grateful for his service to our country.

    We will keep you all in our thoughts and prayers.

    Love and Sympathy, Morgan and Marla Dague

  • Art was a valued friend. He made everyone feel important. I think he got some of his great sense of making everyone fell important from his mother Alice Cassell , who was my Latin teacher for 2 years!!! She raised a great son. In turn he raised some great “kids” as well as giving a boost to all his math students, Bless you all . I know he was very proud of you. Love, Ellen Shultz

  • Deepest Sympathy to the Family! Thinking of you all with thoughts and prayers. RIP Art!

  • A 1945 classmate of my dad, Donald Burgess. I had him as a substitute math teacher in high school. May God give your family comfort and peace.

  • Mr. Cassell was a great math teacher to have, challenging me to do my best. What a fine person to have lived on this planet for so long. His energy will be missed, and my condolences to the family.

  • We were so sad to hear of Art’s passing. He was such a wonderful teacher to many of us, wonderful friend and person. He was always so good to my parents; visiting them often at the Living Center. They just loved his visits. He would walk from home to visit and then walk all the way back home again!! He will be missed by many! He was such a good example to younger generations. We are thinking of all of you in the family at such a time as this.

  • So sorry for your loss, prayers for the family of Arthrur Cassell and remembering all the great things ,love he had for his family and friends ♡

  • So sorry for the loss of your father, grandfather and great grandfather. I always enjoyed talking with Art when I saw him.

  • My deepest condolences to the Cassell’s. Art taught me math and I remember his dry sense of humor. He was also an excellent teacher. I remember him attending my father’s funeral almost twenty years ago. My father was also a teacher at Mt. Vernon high school. Art remembered me from high school and recalled that I was a good student. I thought that was pretty impressive given all the students he had over the years. I’m sorry to hear of his passing. He was a great teacher and mentor.

  • I am not sure how I met Art. It must have been through something musical at one of the Mount Vernon churches over the years. He loved my singing and organ/piano playing and would find a way to make sure I knew how much he appreciated it. Always a kind word, a smile and some dry humor (my favorite) thrown in. A good and gracious man who always had time for me. We have lost so many of his style, may we all share a little “Art” as we move through our days. Blessings and peace to all who loved and were loved by Art.

  • Art was a most respected teaching colleague. I am sad to learn of his death. I send heartfelt condolences to his family.

  • I was very sad to learn of your father’s passing. I am a former student (1981) and have very fond memories of Mr. Cassell’s math “parties” (exams). My thoughts are with you all in your grief.

  • We were so very saddened to hear of Arts passing. May the Lord comfort you and give you peace in this time of Sorrow .

  • To the Cassell Family,
    The Rhoades family is very sorry to hear that your father and grandfather passed on Friday. Thoughts and prayers to all of you during this especially challenging period. He had a profound impact on all of us and we all are better because we knew him. May he Rest In Peace.
    Stephen, Amy, Levi, Carson and Wyatt Rhoades

  • Marge and I would like to extend our sincere condolences to the Cassell family. Art was a wonderful, patient and kind teacher. He was my Algebra 2 teacher and later a friend as we both worked retirement jobs at First Knox . I can truly say that he was a Teacher’s Teacher in every way. Rest In Peace Art.

  • Art Cassell was a fantastic math teacher I remember well! Inwas home for my Uncle’s celebration of life a few years back and he walks in asking if I remembered him! I laughed, of course I do!
    We had a nice talk that day!
    I know all will remember him in positive memories!

  • Kathie Cothren Shimoloens
    My thoughts and prayers are with you and your family. I wasn’t a big fan of math class but I enjoyed having your dad as my teacher in high school. He was such a wonderful man.

  • To the Cassell family,
    My deepest sympathy for your loss of one great guy! Art was a teaching colleague who was deeply respected by fellow teachers and students. I also had the privilege of relying on Art to sell tickets for the athletic department for 18 of his 56 years while I was co-AD and assistant AD at MVHS. He took great pride in always balancing his ticket box! Art will be missed! My thoughts are with you during this difficult time!

  • We remember Art and Joan very well. We were first-time visitors to the Congregational UCC Church in Mount Vernon. That afternoon we heard a knock on the door and Art and Joanne were standing there with a raspberry pie. We thought anyone that would bring us pie was a church for us. We never forgot the kindness. Rest in peace Art.

  • What a good teacher he was! Mr. Cassell was my teacher in my senior year of high school.. He had a way of keeping order in his class just with his very dignified manner. Although I always felt that I was ‘no good’ in math, he was patient and never judgmental. One consequence is that I remember feeling so interested and involved in the very difficult mathematics he taught. (I never ventured into calculus, but I did take advanced trigonometry and advanced algebra with him).
    This was many years ago–1966-67–but I remember him with such affection and respect. Although I seldom thought of my high school teachers outside of the classroom, now I imagine that he was very brilliant, to have taught such difficult mathematical subjects to highschoolers. I am glad that he had such a long life. It sounds like he was surrounded by respect and lovingkindness his entire life, and that says a lot, both about him and about the loved ones who were with him at the end.

  • Dear Cassell Family; I never had the pleasure of having Mr. Cassell as a teacher. But when I was a freshman in high school we used to have pep rally’s in our biology class on Friday’s. Our teacher was one of the football coaches and we had several football players in our class. Mr. Cassell gave tests to his Algebra 2 students on Fridays right next door. He would pound on the wall to tell us to be quiet. My mom and dad knew him through Farm Bureau and farming. He was in Country Court when my dad was there and my mom was there. He was always so friendly. My deepest condolences to your family. He was a wonderful man.

  • To the Cassell family
    You have my condolences for the loss of your father. He was a wonderful man, and a great teacher. He survived six years of Stansells in math and did so with grace and good humor, and a wonderful gentle manner. I’ll remember his kindness when he came to the Memorial service for my mother when she passed in 2012. A totally unnecessary gesture, since none of us had been in school since the 1970s, but a gesture of incredible compassion.

  • It is with great sadness that I write to extend my sincere condolences to the family of Mr. Art Cassell. He was truly a great man and one of the best teachers I had at Mount Vernon High School. I remember well his patience and teaching skill guiding a bunch of us through high school calculus and credit him for single-handledly preparing me for Plebe Math at West Point the following year. But as I recently learned from reading so many wonderful tributes to this wonderful man, Art Cassell was much more than just a teacher of math. He was an active, involved and contributing member of the community who gave of himself for the betterment of his fellow citizen. A true role model for others to follow. God Speed, my friend. May you rest in peace.

  • I am so sad to hear of the passing of Mr. Cassell. He was my favorite math teach in high school as he had so much patience with me and helped me realize the importance of math in every form in our lives. He kept order in class and was always willing to help you if you ask. He was a wonderful man. He will be missed by many.

  • Art was an excellent teacher who prepared his students well for college classes. I remember how he and his wife were at every home basketball game. He was a true gentleman and had grace. He was a blessing to many.

  • Jeff, Brian,Alan and family,
    So sorry for your loss. Art was a good man and awesome neighbor. Our families shared many great times together. Art and Joan were too of the kindest people I have ever known. They welcomed me in there home many times and treated me as one of there own. I have so many fond memories of them both. I had nothing but respect for both of them and it was a true blessing for me to know them for many years.

    I was in Mr. Cassell’s Algebra class when his first son was born.
    Mr. Cassell was a great teacher and always avaible to help a student( and I always needed help)’

  • Just wanted to send our sincere condolences & sympathy to all of your families. I have fond memories of him being one of my teachers. He had such a great reputation of being such a wonderful teacher so I was thankful that I got in his class. I always enjoyed seeing him at the Ticket counter for the football & basketball games. I’m sure he felt very proud & blessed to have such a loving family. Cherish the special & happy memories. Sincerely, Brian & Brenda Stafford

  • Mr Cassell was an uncommon man. He attended the 50th Reunion of the Class of ‘62 , and was all smiles and full of humorous memories. I saw him right after he took up residence at Country Court…..he was reading the paper in the center courtyard. Yes, a super intelligent man reading the paper. That doesn’t happen too often anymore….intelligence and a daily paper; are they things of the past? I asked him at the Reunion if he remembered the Tanner Family? I KNEW he would remember my super intelligent brother (Bill Tanner) but doubted he would remember his less-mathematical gifted little sister (me) and with his usual kind response he assured me that he remembered me. (Why? I didn’t ask). Rest In Peace, Mr Cassell – there are SO many students who loved you dearly.

  • Dear Cassell Family, Please accept my deepest sympathy at your father’s passing. Art and Joan Cassell were pillars in the community. It was a pleasure to be a part a church community with them, too. He and Rob shared a November 30th birthday along with Winston Churchill. All memorable-right? Such a caring and knowledgeable man whose presence was felt in so many ways and places. May he Rest In Peace. Sincerely, Lynda Weston

  • Jeff, Brian & Alan
    I am sadden to hear of Arts passing. My thoughts and prayers are with you all.

  • As the brother in law and sister in law who were married just a few months before Joan and Art, we recall the perpetual humor of Art always reminding us that he was not invited to our wedding. Well, we didn’t even know that he and Joan were serious!! Every one of Art’s recent letters repeated this reminder. The obituary and comments by a small Ohio town captured his wonderful personality to a “T”

  • Jeff, Terri and family.
    So sorry to hear of Art’s (he’ll always be Mr. Cassell to me) passing. I so enjoyed having him as a teacher. He definitely loved his subject and passed it on to his students.
    Deepest condolences.
    Judy Jones

  • Jeff, Brian and Alan and family,
    Susanne and I are so sorry for your loss. Art was a true gentleman with a great sense of humor, and we always enjoyed the rare occasions visiting with him and Joan over the years, especially their 50th wedding anniversary celebration. Our thoughts are with you during this difficult time, and we send our deepest condolences.

  • What a super guy! My deepest sympathy to the family. When first attending First Congregational UCC in Mt. Vernon, it was Art that came up to me and invited me to choir practice. That started my choral singing. The rest is history! Peace!

  • At a time like this, words are hard to find to help ease your pain. Praying for and thinking of your family. So glad you have memories to cherish.

  • Alan, Jeff, Brian and families,
    Art (Joan) were wonderful neighbors. I enjoyed talking with him and all the stories he told me about their lives. I visited him at Colonial when he moved there. Cherish your memories. He once told me I want to live to be 85…….well, he did that and more.
    I was always amazed at how they both continued their daily walks and visit with neighbors along the way. Larry Layman

  • Dear Family of Art,
    We remember Art as a vibrant member of First Congregational UCC. The many tributes to him are evidence of the love he spread to others. We pray our Lord lifts your burden of grief at his loss with many, many fond memories.

  • SO SO SORRY. What a great man,father,and teacher. Cassell family have my prayers. He lived a great life. Bob Harrod

  • My sister, Betty Monk Barnett, and Art were in the same high school class. Both were very faithful in attending their class of 1945 reunions . Art was alway welcome
    and oftened attended the class of 1962 reunions. He was a wonderful math teacher and his kindness made the difference for me getting into and graduating from college. I struggled in algebra II and got a D
    I asked Art , Mr Cassell, if I could retake the class and he said sure. I got an A and that layed the ground work for the rest of my math and science classes to come. I have often wondered how things would have turned out for me if he had said no.
    Thanks Art for the second chance.
    Don Heagren DVM

  • To the Cassell Family,

    Grace and Peace,

  • To all of the Cassell family,
    Without a doubt, Mr. Cassell was one of my best and favorite teachers over 20+ years of education! I always enjoyed his dry wit and his dedication to our learning. I had him for two years of advanced mathematics (junior and senior). Never was I bored but always challenged to do better. What an honor for me to have had him as my teacher!

  • Deepest condolences to Arts family! Sounds like he was an amazing man!
    Erin Brian Burger family

  • Condolences to the entire Cassell family. I was crushed to learn of Art’s passing, and you are in my thoughts. He was absolutely one of my favorite teachers back in the day at MVHS. He will never be forgotten by his many students!

  • Dear Jeff, Alan, Brian and family,
    I send my deepest sympathy for the loss of your father, my colleague and friend. He was a wonderful teacher and a beloved member of our community. I will always hold fond memories of his unique sense of humor and his dedication to your Family and our schools. He will be missed. Love and peace be with you. Always-Joyce

  • Art was my father-in-law for over 20 years. In all that time, I do not recall him ever raising his voice in anger or disparaging anyone. He was a good, good man and father; I was privileged to have known him and will always have fond memories of him.
