David Frederick Poertner

David Frederick Poertner was born in St. Charles, MO, October 1, 1940, to Vernon and Evelyn (Luetkemeyer) Poertner. He peacefully passed from this life on September 17, 2026.

Dave demonstrated a great work ethic and was dedicated to all that he did: devoted husband (64 years), father to 3 (60+ years), tool designer at McDonnell Douglas/Boeing (51 years), card club (40+ years), church volunteer (60+ years), Lutheran School Board President, Indian Guides, Boy Scout Leader, and perennial 2nd-place finisher at Family Game Night. He was a life-long Lutheran, a member of Immanuel St. Charles, 1940-1961 and 1973-2025, and Our Savior St. Charles, 1962-1972. His faith was evident to all. He was known for punctuality. Dave loved to laugh, had a quick wit, and, in fact, may just be the original dad joker.

David is survived by his wife Dr. Grace (Schwane) Poertner; children Daniel (Debbie) Poertner, Timothy Poertner, and Sarah (Michael) Popp; grandchildren Hector, Robby, Samuel, Andrew, Richie, Kallub; his great-grandchildren; niece Julie (Darrel) McDowell; multiple Schwane in-laws, nieces, nephews, great-nieces, great-nephews, etc.

David was preceded in death by his parents Vernon and Evelyn (Luetkemeyer) Poertner; sister Elizabeth (Poertner) Hancock; grandparents Fred and Alma (Budde) Poertner, Oscar and Bertha (Moentmann) Luetkemeyer; aunts and uncles including Howie and Cecelia Luetkemeyer; in-laws Rev. Walter and Helen (Kramer) Schwane as well as many cousins and second cousins.

Memorials may be made in David's name to Immanuel Lutheran Church.
