Arnold Lewis Larsen was born on either September 6th or 7th 1927 depending on who you asked. His mother Minna (Rasmussen) Larsen and father Lewis Christian Larsen delivered him at home and the doctor, who arrived the next day, wrote the wrong day as Arnold’s birthday. Minna and Lewis had not picked out a name for Arnold yet, so his original birth certificate in addition to having the wrong date had his name as boy no name Larsen.

His youth was spent on an 80 acre farm near Fiscus Iowa. Arnold grew up witnessing great changes to agriculture in America. He started working with horses and watched as farming moved to tractors and other machinery. He personally experienced the change of having to hand pick corn to seeing massive combines do the same job. He often bragged about graduating second in his high school class. Upon further questioning you would find out that his class only had seven kids, but he was in the top half. He went to Dana Collage in Blair Nebraska after high school. While there he caught pneumonia and was sent home. While recuperating at home he met Dorothy Ann Lauritsen who he married on June 8th 1950. On April 5th 1951 their first child was born, Roger Arnold Larsen, on August 30th 1955 their second child was born Amy Sue (Larsen) Brown.

Arnold is survived by his wife Dorothy Ann, his son Roger Arnold Larsen and wife Sally, and daughter Amy Sue (Larsen) Brown. He has three grandchildren Jessica Thressa (Larsen) Spinks her husband Jon Spinks, Sean Karl Brown, and Matthew Eric Brown (wife Katie). He also has two great grandchildren Ashlynn Julia (Larsen) Spinks and Logan Jon Spinks. He came from a family of hard chargers his oldest brother Dr. Lawrence Larsen MD deceased (surviving wife Betty), his sister Neoma (Larsen) Steen LPN deceased, Anna (Larsen) Berg RN, Rev Dr. Peter Larsen (wife Inetta) and Dr Philip Larsen PhD (wife Sandra), and brother-in-law Don Ray Lauritsen deceased a very successful farmer (wife Joan) and several nieces, nephews, and friends.

Arnold has worked several jobs throughout his life. He was a farmer, he worked in a gas station, drove a gravel dump truck, and at fifteen he drove a school bus. After he got married, Arnold and Dorothy Ann lived on two different farms but, before long he wanted to go back to school where he eventually received his PhD from Iowa State University in Ames Iowa. From there he took his family to Washington DC where he worked for the United States Department of Agriculture in Beltsville Maryland for six years. In 1970 he took his family to Fort Collins Colorado where he managed the Colorado State University Seed Testing Laboratory. There he created a training program to develop and train future seed analysis that is now used nationwide. He retired from CSU, July 30, 1993.

In addition to his different careers Arnold did volunteer work. He was always there to help a friend with a project. He worked on a sod farm to help a neighbor in Maryland. There were times he would help doing anything from moving furniture to putting on a new roof. He was a member of church councils in Maryland and Colorado. He sang in the choir and helped youth groups. His favorite hobby was photography where he took family pictures, church events, and seeds to be used in his seed analysis training program. He was a member of several professional societies and served on their board of directors. Ultimately he was known worldwide in the seed testing and certification community.

Arnold passed peacefully in his sleep at home while being attended to by his family at 7:10 AM May 6th 2020. Ultimately he didn’t just love and serve his immediate family consisting of wife and children, but grandchildren, great grandchildren, brothers, sisters, cousins, nephews, nieces, friends, neighbors, and anyone that needed help. The world is a better place for his having been here. I’m sure that our four legged companion Muffin will be waiting for him as he goes to his reward.

I loved visiting Colorado not for the beautiful scenery but because of Uncle Arnold and Dorothy Ann. I always felt so welcome and we were always laughing. I especially remember sitting around the campfire when we stayed at the cabins on the Pouder river. I will continue to think of you when the violets come out in the spring and I break into song- “Sweet violets, sweeter than the roses”. Love you and will miss you Arnold

I will miss Arnold .
He was a great mentor and smiling face to me when I arrived at csu.
He always made me feel welcome and supported.
We had great discussions about fixing house and yard issues since we both lived in the same neighborhood
He was one of the quiet heros and made the world a much better place
I send my condolences to his family for their loss

Dorthy and kids I just wanted to share the wonderful memories I have of Arnold. The world has lost a truly great man. I worked on multiple projects with him even though our professional life’s only overlapped a little over 10 years. I never had anything but respect for Arnold and never heard anyone say anything but good about him. I am so sorry for your loss. May your memories be comfort during this time of loss.

Arnold was our neighbor on S. Bryan for many years, colleague at CSU, and fellow member of Shepherd of the Hills Lutheran. He was the friendliest and most helpful neighbor anyone could possibly have. Our sympathy and condolences to Dorothy and the family.

Applewood Seed Co., established in 1965, began seed testing in the early 70s. Arnold and his laboratory was the source of several of our analysts over the years. These analysts took their seed training under Arnold which was always very thorough. In fact, Arnold along with Louis Bass at the National Seed Storage Lab were both instrumental in helping us set up our own certified lab. Arnold was always the most honest, open and helpful of people that I have known. You could always rely on him for objective and thoughtful evaluation of any seed quality problem or industry issue. We could always rely on the accuracy of tests done by the Colorado State Seed Lab during his tenure.

On personal level, Arnold was always a pleasure to spend time with and I consider him a wonderful asset for the industry and the world.

I came to Colorado, partly due to Arnold. The two of us shared a view of seeds and nature together. More than a mentor, a true friend. The world has been blessed to know him.

Arnold was a kind gentle man with a passion and love for seeds. My favorite story that Arnold told me was about when he started a small dairy farm in Iowa. He said that he bought 10 dairy cows with the hope of increasing the herd as he had heifer calves. As luck would have it, in the first two years of those 10 cows producing calves, 20 in all, only 2 were heifer calves. Arnold told the story with a smile on his face and he believed that was why he went on to graduate school to get his PhD.

My condolences to all the family and friends of Arnold.

Arnold was a soft spoken man with a good sense of humor and easy laugh. Sweet Dorothy Ann was the love of his life and always laughed as his humorous comments. I wish I knew more about his work at the university. I am sure he did his part in making his knowledge of plants and seeds go toward nothing but good. Uncle Arnold will truly be missed. PS: Did any of you ever see a more beautiful head of hair!?!

We’ve known Arnold since the early 1970’s. I still remember the first time we met. Our church, Shepherd of the Hills, had a couple’s club and for whatever reason we were at someone’s house and they had a piano. Arnold and I spontaneously set down at the piano and begin playing chop sticks. I’m pretty sure that was the full extent of piano playing for either of us and thus begin a lifelong friendship.
Some years later, I had taken up flying and Arnold thought it would be fun to fly around Fort Collins and take some pictures, so we did. He had two cameras and we flew all around the Fort area, Kodak, CSU, etc., taking pictures only to find out neither camera had film it. As I recall, I think something similar happened at our daughter’s baptism.
After retirement the four of us would have lunch at various restaurants which frequently included a long drive a couple of times a year. These got more frequent as time went on until just about every month. Usually our drives would be a trip up the Poudre canyon some times only as far as Misawaka. Other times all the way to Walden and at least once or twice, all the way to Woods Landing with lunch along the way of course.
We also both enjoyed “The Great Courses” which we shared on occasion, Arnold being much more diligent than I.
Arnold was a great guy and a great friend. We will certainly miss these times together but we will always have the fond memories.

I had the privilege to serving as department head for a number of years during Arnolds's tenure. Arnold was always well oranized, thoughtful and deeply committed to the seed lab. It prospered under his leadership.

On the lighter side the department had a bowling team but Arnold didn't participate on the team and as far as we knew he probably didn't know how to bowl. Then Arnold voluntereed to sub for someone. He bowled in the mid 500's that night and we new we had found a pro!

My deepest sympathies to Dorothy and his family.
