Arthur H Clark III

Obituary
Arthur Harrison Clark, 73, passed away peacefully at home in Green Valley, Arizona, on November 18th, 2025 surrounded by his family.
Art was born to Arthur H. Clark II and Donna (Wright) Clark in Vincennes, Indiana, and moved to Wheaton, Illinois, when he was 6 years old. After graduating from Wheaton Central High School he attended the University of Arizona for one year before transferring to the University of Colorado Boulder, where he graduated with a degree in Math and Computer Science. He went on to receive his Master’s in Marketing at Louisiana State University in Baton Rouge. After college, he moved to Houston, Texas where he worked for Digital Equipment Corporation, and met his wife, Kathy. They were married 2 years later and his job with DEC took them to Henderson, Nevada and Boston, Massachusetts with Apollo Computer Co. They eventually settled in Monte Sereno, California where he worked for PCAD, EDA, Infoseek, eWalk Software Corp. and they raised their 4 beautiful children.
Always the ultimate competitor, playing on the football team in high school and the wrestling team in both high school and college, he went on to become the President of the rugby club, competed in more than 20 triathlons, ran the Boston Marathon, and culminating in completing the full Ironman Triathlon in Cape Cod.
Art was also a man of adventure and had a love for travel. With Kathy’s job with Delta Airlines, they were able to mix his love for athletics with traveling the world; riding their bikes through Greece, bike racing through Mexico, hiking in Peru and Brazil, and scuba diving in Australia, the British Islands and Hawaii.
First and foremost though, Art was a deeply involved father of his 4 children; Kelly, Kristopher, and twins Karilyn and Kyle. Coaching soccer and wrestling teams, teaching life skills, helping with homework, and inventing stories at bedtime with the kind of creativity that made their childhood feel slightly magical. With his no-quit attitude - a kind of discipline, toughness, and determination - he passed his work ethic directly on to them. It fueled athletic careers, shaped their own work ethics, and gave them the confidence to believe they could do anything they set their minds to. As adults, they recognize what a rare gift that was. His dedication extended beyond the immediate family as he welcomed his children’s friends into the mix, teasing them, roughhousing with them, and poking at them in the exact ways his kids now catch themselves doing with the next generation. He became a kind of bonus parent to many.
In addition to his love for his children, he loved his wife Kathy deeply. His kids saw it clearly in his later years - the way his face lit up when she walked into a room, the joy he felt simply being near her. Their marriage of 45 years was filled with travel and shared curiosity, becoming a quiet roadmap for how to love, how to explore, and how to keep choosing the adventure.
Art is remembered as a builder: of memories, of adventures, of confidence, of chaos, of laughter, and of the kind of family culture people look back on and realize was rare. He was happiest outside, exploring someplace new, or anywhere surrounded by his friends and family.
He is survived by his wife, Kathy (Gidel) Clark; his children, Kelly (38), Kristopher (35), and twins Karilyn (31) and Kyle (31); his sisters, Terri Burney and Debbie (Bob) Stevenson; Terri’s daughter, Brandy (Nick) Oostman, and her son, Daniel; Debbie’s children, Nicole (Matthew) Betts and Bryan (Miyah) Stevenson; Kathy’s mother Mary Gidel, her sister Joyce Gidel (Jay) and her daughter Lindsay Jones, her brother Rob Gidel and his children Ali (Jarrod) Lord, Rob (Jacqui) Gidel, Jill (Brian) Smith, and a wide circle of friends who will remember him for his humor, his imagination, his relentless determination, and the way he made life feel full. Art will be greatly missed.

Art clearly lived an accomplished and successful life with Kathy and their children. After reading the other memories posted Art was consistently was a great friend, coach, boss and mentor to many people he knew.
I remember him for his quick wit, intelligence and being as avid reader, always expanding his knowledge. On a small but meaningful side note; Arts Father picked me up when hitch hiking back to I.S.U. from Wheaton one day. Arts father was a character and extraordinary man, so its no wonder Art turned out so well. That said, Arts Mother was an equally wonderful person whom I remember fondly, too.
It is so sad the your amazing life was cut short by an awful disease. I lost a former work friend/mentor from the same illness just a couple years ago. Its just so tragic! However, I can safely assume that Art is laughing and smiling over all of his friends, family and co-workers. You did good Art - thanks for the good times and friendship in our formative years





Your love for your children and your wife was ever-present and inspiring. You created a home characterized by warmth, laughter, and unconditional support. As a father, you were not only loving but also an incredible role model who raised
your children to be the wonderful people that they are today.
What I will particularly remember
your unwavering positive attitude and your dedication. Your were always the one who brightened the mood with your good humo. At the same time, your commitment to youth and sports was remarkable.
You helped countless young people realize their potential – a dedication that extended far beyond your own family.
I will always remember you as a good, dedicated, and always cheerful person, whose positive influence continues to live on in your family and your community. It was an honour to known YOU. THANK YOU ❤️ (The Nanny)

Art was a member of the Houston Heathens Rugby Club in Houston in the late '70's. The Heathens won more tournaments and games when Art was a member than any team in the U.S. The Heathens were 80 members strong and would field 3 strong sides every weekend. A force to be reckoned with and Art was front and center.
Art was a fierce competitor on the field. And probably comes as no surprise after reading about his marathons and triathlons that Art was always in tip top shape. Art was class act and the best teammate ever. I speak for Heathen Nation to say we are proud to have known and played the game of rugby with Art Clark.
Lasting memory was that Art had the best smile and laugh of anyone on the team, a happy image to remember the boy.
It is with great privilege, pride and pleasure to share with Art's family and especially his kids the person we knew and loved.

That was Art in a nutshell, decades (to quote Kathy) of "Oh Art"
We will all miss you

I learned several sales tactics during those trips: "Never argue with your comp plan" & "Feel Felt Found" were among the many words of advice he always gave.
After Infoseek I moved out of the bay area. I had an idea for another startup and wrote some code. The first person I thought of to help was Art. Of course he was all-in. We spent the next decade building ewalk virtual tours. It was definitely an adventure. Lots of work and lots of fun figuring out how to make things work. We spent many days taking pictures and going through all kinds of homes for sale. Art always kept us on the straight and narrow as far as product direction and business focus. He did the work to figure things out and not guess at decisions.
I will always admire Art for his work ethic and fun approach to getting things done. I miss him but will always remember our history together.
This is how we remember our dear friend, Art.
We have had the great pleasure of knowing Art, Kathy and family for several years while living in Green Valley, Arizona. Everyone loved Art's zest for life, infectious smile and great love for Kathy. How proud he was of his children and the people they have become!
Art's quiet determination to do the things he loved inspired us all. We are forever grateful for years of friendship and wonderful times together.
We miss you Art!
Our hearts go out to Kathy, Kelly, Kris,Kari and Kyle.
May you find comfort in your memories of an amazing husband, father and friend.
Love ❤️ Donna and Paul

I am grateful for the time I was able to spend with him while I lived with you. I will always remember Art as an incredibly warm-hearted and wonderfully humorous person.
Art speaking his funny German, his excitement about Nudelaufenlaufen, sleeping every weekend on the floor in the family room with the kids, me catching him late at night with the huge peanut-butter jar — and the next moment he was out on the patio railing demonstrating to me that ants don’t like peanut butter. Or when he came home from work and was once again annoyed that the Nanny had beaten his TETRIS high score. And in the mornings, when he stood in the kitchen in his always-good mood, with his big cup of coffee, dressed in his suit and holding his small travel bag — and the whole family wasn’t allowed to say anything except LUAMU. And if someone accidentally said anything else, he would simply start all over again with each person.
I am thinking of you and the kids so much during these difficult hours.
Falk and the children also want to express their condolences to you and the kids.
