Kathleen M. Seilheimer

August 29, 2018

Kathleen M. “Kathy” Seilheimer, of New Auburn, WI died on Wednesday, August 29, 2018, after a short time at the Cornell Area Care Center after dealing with cancer for 6 ½ years. She was born on February 8, 1944 to Charles and Kathleen A. (Grove) Seilheimer in Chicago, IL. She attended a one-room schoolhouse on Long Lake and graduated from New Auburn High School in 1962. She graduated from Eau Claire State Teachers College in 1966, later earning a master’s degree from UW-Eau Claire.

Kathy grew up at the family resort on Clear Lake and enjoyed waterskiing with the summer neighbor kids. Her first two years of teaching were in Rockford, IL and then she settled into her 32-year career at Palatine High School in Illinois. She taught biology and math; including A.P. and the gifted and talented program, retiring in 2001. She also taught for a few years at McHenry County Community College night school. With summers off she was able to travel extensively. She made several trips to Europe, often chaperoning high school student groups. She also went on a photo safari in Africa and took a nephew to the Galapagos Islands.

Kathy was a talented seamstress, cook, woodworker and basket weaver. After retirement she returned to rural New Auburn and she had more time for community involvement. She served on the New Auburn school board and was president. She also headed the New Auburn branch of the Bloomer-New Auburn Food Pantry. She was the chief election official for Rusk Township, Rusk Co. She was a longtime member of Island Chain of Lakes Association and more than one Red Hat group.

Kathy had strong opinions, was generous with her talents, related well to her students and inspired them to continue their educations, and valued her many friendships.

She was preceded in death by her father, “Charlie” in 1971; mother, “Sunny” in 2002; her brother, Allen in 2005.

She is survived by her nephews, Titus (Amy Fettes) Seilheimer of Manitowoc, WI, Jacob (Megan Yaple) Seilheimer of Manchester, NH; grandnephews, Tor and Leif Seilheimer of Manitowoc, WI; sister-in-law, Sandra Hatch Seilheimer of New Auburn, WI.

The family would like to thank her extensive medical team at Lakeview Medical Center in Rice Lake for their continued care and support.

  • Kenneth Heydrick, Ed.D. The dominant influence on me to pursue science was my Biology 2 teacher at Palatine High School (IL) - Kathleen Seilheimer. Ms. Seilheimer was an extraordinary teacher. She taught me both Algebra and Biology 2. I can still remember how intelligent and thoughtful she was to us. I know that at least 7 of our Bio 2 classmates received their MDs, PhDs, etc. in the science or medical field. Wow. Ms. Seilheimer was dedicated to science and kept us engaged in the classroom. Along with my chemistry teacher, Ken Spengler, these two teachers inspired in me to pursue science education (36 years) — from a high school biology/chemistry teacher to the director of science curriculum for the State of Texas. I always made a point to stop by PHS to thank my teachers for motivating me. May God bless Kathleen Seilheimer. Thank you for being that first point of light for my professional career. I will always be grateful to you and your influence, awakening, and spark.

  • Lori Jessen Whitis I had Ms. Seilheimer for AP Biology many years ago. She was very motivating and encouraged me to pursue my medical degree, which was my dream. I now am the medical director for the Chippewa Valley Free Clinic in Eau Claire, and I was thrilled to have a chance to reconnect with Kathy a couple of years ago. Please know that her influence continues to ripple throughout many communities through her former students.
