Leon Carl Mosteller, 78, of rural Bern, Kansas was born August 22, 1943, in Humboldt, Nebraska to Oliver and Eleanor (Dick) Mosteller.  Leon was raised on the Mosteller Family Farm near Bern, Kansas and attended Bern Public School from 1950-1961.  He graduated from Bern High School with the class of 1961.  After graduation, Leon worked with his dad on the family farm before joining active duty with the U.S. Army on February 15, 1966.  He served his country while stationed in Germany during the Vietnam War until being honorably discharged on January 26, 1968.  Leon then served in the U.S. Army reserves until his discharge on February 16, 1972. 

On June 15, 1975, Leon was united in marriage to Karen Threlkel at the United Church of Christ in Centralia, Kansas.  To this union three children, Ross, Robert and Karla were born.  The couple raised their family on the Mosteller Farm where Leon was the 4th generation of Mosteller men raising Shorthorn Cattle.  Leon was the custodian/bus driver for Bern Schools from 1988-2011 and then drove bus for Sabetha Public Schools from 2011-2021.  Leon was known for his ability to carry on a conversation with anyone and everyone.  He was proud of his family and was a presence at any activity they participated in.  He especially enjoyed the county fair and was known by many for always being there to lend a helping hand or share a story.  Leon was definitely one of a kind and will be remembered by many.
