Hike in the Tijuca Florest

I took a class from Dr. Fisher in 2019, and I liked it so much that I signed up for another in 2020! I went into that first class not liking mathematical proofs, and I came out loving them. It was in his class that I started to understand how beautiful math is. He used to talk about how the people who originally proved the ideas we were learning and that was fascinating to me. 

I enjoyed going to his office hours, because I could push back, and he would keep explaining until I understood. He was also very patient and generous with me in class. And funny! 

His love for mathematics was infectious and it's something I'll carry with me for the rest of my life. Condolences to his family and friends.

We are so sorry for your great loss.

I was very sad when I heard the news of Todd's passing. One of my favorite memories of Todd, was how much he cared for Mary. He always treated Mary and their kids with love and respect. I admire him for his discipline and tender heart.

Another one of my favorite qualities about Todd was his strong belief in his religion. He truly knew of a surety that we are all Children of God, and he lived what he believed. I know that Todd and his family will be reunited once more.

I’m so sorry to hear about Todd’s passing. Although I had not been in touch with him since high school, I very much remember him from the neighborhood days back at Lawton elementary and every memory and impression I have of him is that he was sincere and kind in a very genuine, meaningful way.  Even as a kid, he was authentic and warm, and in reading his obituary, it is clear that his beautiful qualities were not only maintained into adulthood, but continued to blossom and impact others. I also remember him as having a sense of humor and of course- being smart! I also remember his whole family being warm and friendly members of the community and I specifically have memories of his dad being the epitome of the “Ann Arbor parent” who is a brilliant professor! I remember when Todd’s dad came to school for parent career day. We didn’t have too many parents coming to school who were cool jobs like firemen- but when Todd’s dad came and explained to all the elementary kids sitting on the floor that he was working on some very complicated scientific research which my childhood brain seems to recall had something to do with genetics (this was like the early 1980s) - it seemed very cool and I remember thinking that the whole Fisher family were geniuses and meeting his dad was like meeting Albert Einstein! 

I hope the entire family can find comfort to carry them through this terrible loss. 

Several years ago I took multivariate calculus from Dr. Fisher. He was clear, kind, and made it easy to get excited about the subject. I treasure the opportunity I had to be one of his students, even for just one class. Best wishes and condolences to the Fisher family.

For Todd's family: I just want to share my sadness for this terrible loss and hope his cheerfulness will remain in all of us. It was great to meet him and work with him. 

Dr. Fisher was my advisor for more than two years. We went to several math conferences together. He guided me and helped me writing papers.  I am grateful for the time I am able to spend with him. May he Rest In Peace. Sending my condolences to his family. 

Michael and I really only knew Todd thru the stories Ellen told. She so dearly loved him and is so very proud of him; what a good man he is. We mourn with the whole Fisher family, and pray for comfort to be with each of you, especially Mary and the children. Life is fragile and precious and the blessings of Eternity await.

Dr. Fisher was/is great. Steady and reliable. I feel like his "Introduction to Real Analysis" class was a good mix of keeping it relaxed and as simple as possible and acknowledging that it was hard subject (the subject is notoriously difficult for undergraduate math students) while also not dialing back the challenge where it counted. Then, even though he only taught the class for one semester, he brought a good level of organization and stability to my ACME cohort (I really really appreciated his review practice tests that he put together for us). He was always friendly and helpful in office hours and I never felt stupid asking stupid questions. He had/has a great smile and a generally cheerful attitude which I know I and a lot of my peers really appreciated - math can be kind of mind numbing sometimes but he always stayed personable.                                       On a more specific level, I once got stuck behind an avalanche at my Sundance job up the canyon and was going to miss a test, but Dr. Fisher quickly responded to my email saying he totally understood my situation and was happy to arrange a later date for me to take the test in the math lab. It wouldn't have been hard for him to say "You shouldn't have put the test off till the last minute" but he willing postponed releasing the graded tests so that I could take it late - a reasonable size inconvenience for him/the class, but a HUGE stress relief for me in an already stressful situation (and a stressful semester in general). Small things add up. I can basically guarantee he was equally willing to work with other students in their individual circumstances, and he made himself accessible.                                                                                                  The math department will definitely not be the same without him but his impact on me and other students will definitely continue. Sending my thoughts and prayers for the family!

Mary and kids: really glad that I and my family had the opportunity to meet with your family. I can not think about Todd without remember  his great and beautiful smile. Hope that this pain and sadness moment be short and his memories  last forever. 

Sending prayers and hugs to your family at this time. Todd and I were grad students at BYU together many years ago. We were teachers assistants together for Calculus. I was always impressed with how he prepared for his classes and the kindness that I always felt from him.

Todd was a great friend, colleague, and collaborator. He will be missed in the department, for his casual conversations that happened when colleagues would spontaneously gather in the hallways, for his enthusiasm for mathematics, and for his joy of life.

I was so very sorry to hear about Todd's illness and then his passing. He was a wonderful person. I knew Todd through Northwestern. I also received my PhD from Northwestern, although a while before Todd did. We got to know each other through our shared research interest in dynamical systems. I remember with great fondness spending time with him about a decade ago when he invited me to BYU to speak in the department. He will be missed, and I wish the best to his family during this difficult time.

Todd was a HS friend who was always so positive and inspiring. Taken from earth too soon. May his family have some condolence and peace in this very difficult time. 💕

Dear Mary, Katherine, Andrew, Aaron and Adam,

Kathy and I are sending our deepest condolences, as are my family and students. Todd has been an amazing colleague, coauthor and friend—and above all a generous and spiritual man, as well as a loving husband and father, who was rightly proud of you all. Even though she only met Todd once, my sister still remembers you all from talking to him. May God hold you in the palm of His hand.

With my love

Boris

Dear Mary, Katherine, Andrew, Aaron and Adam,

Sending our deepest condolences for your terrible loss.  Todd was a dear person, with such intelligence, warmth, kindness, generosity and good cheer.  We were blessed to have him as a student, colleague and friend. You were the pride of his life, and for such a modest person, he could hardly contain himself when talking about his family.  We will miss him so much.  May his memory be a blessing  

Love,

Amie and Benson (and Beatrice and Felix)
