F. J. “Lutz” Denning, born on February 17, 1918, passed away at the age of 99 on September 14, 2017 at his home in Lamar, CO with his family by his side.

Lutz was born to Michael and Pauline (Basgall) Denning in Ellis, KS. Lutz was the 7th of 8 children. He had 5 brothers – Frank, Tom, Vic, Mike and Mac and 2 sisters Josephine and Georgeanna. Lutz married Katherine (Katie) Gerlock on November 25, 1941 (12 days prior to Pearl Harbor being bombed) and was called to serve in WWII in the Army/Airforce May 1942.

Katie accompanied Lutz through the end of the war and his discharge in November, 1945. During this timeframe, 2 children were born of the marriage, Pauline and Joann. In 1946, Lutz and Katie settled into farming in the Holly/Hartman areas. Through the years to come, they continued to build their family with the births of Mary Alice, Darlene, Lenny and Jane.

Lutz was never afraid of hard work and provided a living and home for his family through many hard years of work at farming, and later traveled to Lamar to work at Cross Manufacturing and NEOPLAN.

As the children grew up and left home, Lutz and Katie moved to Lamar, but continued to enjoy visits to the farm to tend to their garden and enjoy time together.

After 68 great years of marriage, Katie passed away January 24, 2010. Lutz continued to live in their home in Lamar and spend time with their adult children and grandchildren. Lutz remained active in the management of his farm in Hartman and the maintenance of his home in Lamar, enjoying the company of his German Shepherd dogs who accompanied him on his visits to the country.

In addition to his loving wife Katie, Lutz was preceded in death by his son, Lenny Denning, his parents, his 5 brothers (including the loss of Mac who was killed in action during WWII) and 2 sisters, in addition to sons-in-law, L. Kenneth Brown and Ron Trumble.

Lutz is survived by his daughters, Pauline (Dallas) Glover of Wellington, KS; Joann Trumble, Mary Alice Henry both of Lamar, CO; Darlene Brown of Coolidge, KS; Jane (Brett Jones) Brewer of Colleyville, TX and daughter-in-law Joni Denning of Dumas, TX, grandchildren Gayle Grubbs, Mark Glover, Curt Glover, Jeff Glover, Mike Trumble, Scott Trumble, Kenny Trumble, Jill (Trumble) Williams, Jana Weimer, Ronnie Brown, Katie (Denning) Johnson, Karli (Denning) Gribble, and Chris Robertson. He is also survived by twenty four great-grandchildren and eleven great-great-grandchildren, numerous nieces, nephews, other family and a host of friends.
