Leonard Fred

Burkhart

Leonard F Burkhart, Sr., age 88, of Yorkville, IL died Sunday, November 8, 2026, at Rush-Copley Medical Center in Aurora, IL. He was born December 23, 1937, in Aurora, IL the son of the late Ralph M. and Margaret (Armbruster) Burkhart.

He was employed as a draftsperson engineer at Caterpillar in Aurora, IL prior to his retirement. He was a member of the NRA, Yorkville Moose Lodge #2371, DANK, and for many years was a volunteer firefighter with the Oswego Fire Protection District. Additionally, he was an avid gardener and especially loved edible plants (vegetables, fruits, and nuts). He also planted hundred trees, shrubs, and vines over his lifetime. Besides collecting everything from model trains to political buttons, he worked tirelessly on family genealogy with cousins. The family genealogy database has over 2,000 relatives in it, which are mostly in the U.S.A.

He is survived by his daughter Sue (Dan) Glenn, stepdaughter Anita Halmagyi, two sons Leonard (Jeff) Burkhart, Jr., Timothy Burkhart, two grandchildren Neil (Marilyn Johnson) Halmagyi, Nathan Halmagyi, two great grandchildren Diana Halmagyi, Francesca Halmagyi, niece Lisa (Gary) Nixon and two grandnephews Taylor Hamilton, Kyle Hamilton, and great grandnephews.

He was preceded in death by his wife Gisela (Hengsmith) Burkhart of 57 years, his parents, and sister Nila (Burkhart) Kelley.

Leonard & Gisela had also raised one hundred (100) Foster Children, so their extended family is extremely large.

A Celebration of Life and memorial service will be held later.

Memorials may be directed to Kendall County Animal Control, 802 W. John St, Yorkville, IL 60560.
