Stillwater resident, Dr. John P. Lloyd, 85, passed away peacefully on Saturday, April 11, 2026 in Stillwater, Oklahoma.

John was born on December 20, 1940, in Tuscola, Illinois to John and Gretchen (Skinner) Lloyd.

After his military service was completed he joined Oklahoma State University as a Professor of Civil Engineering, where he impacted many students and colleagues over the years.

John first married Heather M. MacAlpine who preceded him in death. In May of 2005, he married Ruth Ann (Boone) Pals in Stillwater, Oklahoma where they built a life together filled with love and companionship.

He found joy in simple things - camping, hiking, fishing, woodworking and time spent with family. He had a special place in his heart for dogs and all animals.
