Tyler and Kim;

I was so sad to hear of  the passing of Doc. I have so many wonderful memories of him on the golf course and basketball court. I'm sure he and Fred are having a cold one up in heaven. Take care my friend!

I remember Charles coming to baseball games. He was such a good grandfather to Justin who played on the same team as our son. I didn't know him well, but know he was a great father to his son and my friend, Tyler.

Dr. Tom Greenwald

I have served as a member on the Research Committee Tuberculosis in Animals of the International Union against Tuberculosis and Lung Diseases while Charles was chairman.
He guided and helped us in many ways to become a rather interesting group of veterinarians from many parts of the world. We attended numerous conferences with him in different parts of the world. Charles visited South Africa to attend a Tuberculosis conference in Pretoria in 1994 and at the same time visited the Onderstepoort Veterinary Institute. While in Pretoria he was guest in our house in the countryside outside Pretoria. Here he very much enjoyed the South African trees and animals.
His passing has left me very sad and I would like to offer my deep condolences to Charles family.
Hildegard Huchzermeyer, retired from the Onderstepoort Veterinary Institute

My husband and I rent a home from Charles. He was always understanding, kind, and loved giving our dog pets when he came to discuss anything. We'd see him walking the neighborhood with his own dog and he was always happy and smiling. We've rented from Charles for 5 years and a big part of why we stay is because of his kindness. Our thoughts go out to his family during this sad time. He will be greatly missed.


I collaborated with Charles for many years when he was Chairman and I was secretary of the Research Committee on Tuberculosis is Animals of the International Union Against Tuberculosis and Lung Disease.We attended conferences for very many years  in various parts of the globe.
Charles was a valuable colleague and friend to myself and the other Committee members.Some of these former members have contacted me on hearing of Charle's passing .
On my own behalf and and also on behalf these former colleagues,I wish to offer our heartfelt  condolences to Charle's family.



So sorry to hear of Charles' passing.  We farm near him and got to know him quite well.  He was so interesting as he talked about his work.  Our heartfelt condolences to all of his family.  Robert Gulbranson

I only knew Dr. Thoen in the last year or so through the Mayo Clinic Alumni Assocation - I wrote a story about him. He called me occasionally, including only a month ago, and was such a kind person. I hope his beloved dog is in good hands.

My deepest sympathies to Dr. Charles Thoen's family. I have had the great honor of calling him a colleague where he exemplified a sincere passion for both science and teaching. His contributions to both will always be remembered and cannot be replaced.

Our heartfelt sympathy to the family. We had the pleasure to get to know Charles and enjoyed many visits. Charles will be dearly missed and fondly remembered by all who where fortunate to have met him.
Our thoughts and prayers are with your family.

Dr. Thoen was a great professor and excellent mentor. He was always ready to help students, especially those coming from overseas.

I knew Chuck very well and worked with him extensively on TB and Johnes in zoo animals. He was so supportive in developing tests for exotics and assisting Zoo Veterinarians in getting Mycobacterium sp. cultures run. His knowledge on the topic was extensive and he was so enthusiastic and willing to share his resources and his knowledge with anyone who asked him. I feel so fortunate to have known him and he will be truly missed. The world is a much better place because of him.

I want to give my condolences to the family of Dr. Charles Thoen.  I have long appreciated the friendship and scientific collegiality of Dr. Thoen as a fellow faculty member in the Department of Veterinary Microbiology at Iowa State University.  His contributions as a citizen of the community, as a teacher and as a research scientist were very outstanding.  Thank you for sharing the time and exceptional talents of your father with us.  

Dick Ross, Emeritus Distinguished Professor and Former Dean, Department of Veterinary Microbiology and College of Veterinary Microbiology, Iowa State University.

Dr. Thoen opened his heart and laboratory to research scientists from Africa. We appreciate his contributions to promoting one-health, one-world collaboration. Our prayers go to his family at this time, and may his soul rest in perfect peace.

Tyler and Kim;
Doc was an awesome guy.  He laughed and smiled so easily.  He made everyone feel they were the most important person to him at that time.  Doc loved to talk sports whether it was Ames High or the Cyclones!!  And he never failed to ask about our kids.

Tyler & Family:

So very sorry to hear of your dad's passing. 
Please know that you and all your family are in our prayers. 
May God assure you of peace and comfort at this time. 

Best to you and your family,
Dick & Marty Miller

It was a great shock to hear of the death of Dr. Charles Thoen! I have known Dr. Thoen since 1976  working on TB  research. The latest work we did together was serving as Co-authors on the latest Zoonotic TB textbook,
He was a quality scientist, a thinker, great father, wonderful friend, and all around a great person. I will miss him very much.
John Kaneene - Michigan State University

I'm sad to hear my good friend Chuck Thoen has passed away. I worked closely with Dr. Thoen since a long ago as 1973 working on TB in zoo anmials and livestock.  We worked hard, published lots and had some fun doing both.  

Dr. Thoen was a well respected colleague of mine in the field of tuberculosis epidemiology.  We spent many hours together thru the years discussing cases of TB in various animal species, the best tests to use in diagnosis, and he was always a champion of the cause to eliminate the disease when and however possible.  His expertise and advice will be greatly missed.     Bob Meyer

Dear Thoen Family, Colleagues and Friends:

On behalf of the members of the American Veterinary Epidemiology Society (AVES), of which Dr. Thoen served as a distinguished President, we send our heartfelt thoughts and prayers to family members and friends.  Because of his outstanding leadership and  many contributions to veterinary medicine, public health and One Health, the world is a much healthier place for animals and people.  Our sincerest condolences on this tragic loss,

Craig N. Carter
President, AVES

Chuck was a great friend and colleague whom I will miss.

My condolences for Dr. Thoen's family. He will be deeply missed.

Veterinary medicine has lost a great and highly esteemed colleague with the passing of Dr. Thoen.  His contributions were many and significant; he gave selflessly of himself every day on behalf of the profession, co-workers, students, and friends. We will miss him dearly even as we celebrate his life.

I had Dr. Thoen as a professor and very much respected him and appreciated his sharing of his knowledge of veterinary epidemiology. He will be missed at ISU.

My thoughts and prayers for the family and friends.  
Dr. Thoen was my adviser in graduate school and he had his hands full with an "old warhorse" from veterinary practice.  We did get my research printed with his encouragement.

Doc was a great friend and neighbor. We lived next door to each other for many years, played a lot of basketball and golf together and enjoyed many ISU games and memories. He will be missed.

My thoughts and prayers are with you. He was my supervisor at the NVSL, on my graduate committee and a friend. He touched many lives.

Bless Dr. Charles Thoen's wife and family.
Respectfully, Sylvia Wade

Tyler, I am heartbroken to hear his news about Doc.  Such a large part my growing up, he was always larger than life itself.  I have so many good memories about the times we spent on the basketball court and just hanging around.  
Byron

It was truly a pleasure working with Dr. Thoen.  He was always a student advocate and caring person.  His expertise and willingness to help students will be missed.  Thank you for your years of service to the College of Veterinary Medicine.

He was a devoted father. He was a great friend.  He was my husband.
Always
Diana
