Jonathan "Jon" K. Ewald 75 of Tiffin, Ohio passed away at his home surrounded by his family on November 26, 2025. He was born March 10, 1950 in Tiffin, Ohio. He attended Old Fort Elementary and graduated from Tiffin Columbian in 1968. He received a degree in Agriculture from The Ohio State University in 1972.

In 1973, Jon Ewald married Diana Lynn (Hopple) Ewald in Tiffin, Ohio, who was his greatest love and best friend for 52 years. His passions were faith, family, and farm.

He was a full-time farmer and was proud to be a fifth generation farmer who spent his life working on his family Centennial Farm which was founded in 1855 and received the Ohio Legacy Farm distinction. He safeguarded his 470 acre farm for future generations with the Black Swamp Land Conservatory which he considered his greatest legacy.

He was a member of the Trinity United Church of Christ in Tiffin and the Old Fort Lions Club. He was a former member of the Old Fort Young Farmers and a proud supporter of area 4-H and FFA programs of which his children and grandchildren were members with animal and farming projects. He also loved sports and was a proud supporter of The Ohio State University Buckeyes and both the Cleveland Browns and Indians. However, his favorite teams were the teams of his children and grandchildren: Old Fort High School, Bowling Green State University, Ohio Northern University, Heidelberg University, Genoa High School, St. Edwards High School, and Hopewell-Loudon High School.

He is survived by his wife, his children: Holly (Derrick) Szepiela, Laura (Christopher) Snyder, Mark (Andrea) Ewald, and Jonathan Michael (Kristinea) Ewald, his grandchildren: Logan (Aric) Recker, Zachary Szepiela, Nathan Snyder, Andrew Szepiela, Aiden Ewald, Joseph Ewald, and Sidnee Ewald, and his great-grandson: Hudson John Recker.

He was preceded in death by his parents Charles Richard Ewald and Marjorie (Kleckner) Ewald.
