Obituary for Arthur Rudolph Kotz

Arthur Rudolph Kotz, passed away on December 20, 2021 at the age of 88 years. Arthur (“Bud”) was born in February, 1933 in Eau Claire, Wisconsin to Arthur and Harriet Kotz. 

At Eau Claire High School, Arthur was dubbed “Einstein’s newest competitor” by his senior class.  Art earned his Bachelor’s degree in Physics at the University of MN, and his Masters and Ph.D. in Physics from the University of WI, Madison. Art married Beatrice M Bruvold in October, 1955. Together they lived in Falcon Heights, Minnesota; Madison, Wisconsin; and then White Bear Lake, Minnesota, ultimately settling into their long-time residence surrounded by nature on the shore of Bald Eagle Lake. Art and Bea spent many days of summer at their lovely cabin on the North Shore of Lake Superior, near Lutsen, MN. They adored their time at this scenic lakeside retreat, and passed this tradition down to their children and grandchildren. More recently they spent several winters at their desert home at Quail Creek in Green Valley, Arizona.

Art treasured his wife and was an adoring father and grandfather. He was kindhearted, generous, and extremely witty. Art was a brilliant scientist. During his accomplished career as a research physicist at 3M, he was named Corporate Scientist. In 1978, he was inducted into the elite Carlton Society “for his many contributions and innovations in the field of graphic reproduction, including electron beam recording… and electronic reproduction systems; for his technical leadership in encouraging the development of pioneering technologies; for his achievements in developing the technical and creative talents of his colleagues.” Art’s primary retirement hobby was astrophotography, allowing him to continue his lifelong hobbies of astronomy and building electronics.

Art was preceded in death by his beloved wife, Bea and their first daughter, Kristen Elaine Kotz, now joyously reunited with them. He was also preceded in death by his 3 siblings (William, Donald, and Marianne).

Art is survived by his son, Arthur Kotz, his wife Denise, and their children, Jenna and Andrew, of Woodbury, MN. Art is also survived by his son, David Kotz of Rosemount, MN, and his sons, Evan and Leif. He is also survived by his daughter, Kimberly Marlowe, her husband, Michael, and their children, Ashley and Jessica of Minnetrista, MN.

Art’s gentle and wise soul touched many lives and was a role model for many. He will be dearly missed.
