W. Slagle Obituary
He was born on June 16, 1931, in rural Kirkwood, Illinois, to William and Ida Slagle. Lyle proudly served his country as a Staff Sergeant in the United States Air Force during the Korean War.
Lyle built a long and respected career at the Idaho National Laboratory (INL) as a Health Physicist and Technical Writer. In 1961, he served as a first responder during the SL-1 accident, demonstrating courage and professionalism during a historic and challenging time.
In 1953, he married Doris Hunzinger, and together they had two daughters, Karen (Daryl) Deringer and Connie (Phillip) Wagoner. They later divorced. In 1986, he married Jean Romine
Slagle and gained a stepdaughter, Donita Land. Jean preceded him in death in 2025.
He was blessed with nine grandchildren: Chiane (Jake) Williams; Lacey Kriegh (Cameron
Dennett); Rick (Rhenda) Mattern; Brandon (Kresada) Mattern; Mallory (John) Malee; Steele (Susie) Deringer; Lindy (Kaelyn) Brewer; Dustin Deringer; and Samantha Deringer. He was also the proud great-grandfather of nineteen and great-great-grandfather of four.
Lyle was preceded in death by his parents, his five siblings, and his wife Jean.
Lyle found great joy in camping and fishing, especially in Island Park, Idaho, where many
special memories were made. He was an accomplished pool player and often laughingly said
he "majored in health physics and minored in pool." He also had a creative spirit and enjoyed
writing poetry about the people and places he admired. Above all, he was devoted to his
family.
Dad will be remembered for his love, caring nature, warmth, and creativity. He will be missed
every single day.
No services will be held at this time. A celebration of life will be held in June 2026
