Ronald Albert (Al) Palladino, age 80, of Columbia, passed away Sunday, November 25, 2018, peacefully in his home. Al was born on February 10, 1938 and raised in Omaha, Neb., the youngest of three siblings born to Louis A. Palladino and Madeleine (Williamson) Palladino. Al was a lifelong devotee to environmental education and conservation, having worked as a high school biology teacher and for nearly 30 years for the Missouri Department of Conservation within the Outreach and Education Division. He was a sometimes artist and always photographer, a keen observer of nature, a hunter and outdoorsman. He passed along his great respect and love for the natural world to his three children with whom he reconnected in his later years. All are grateful for the chance to have been present for him. Al is survived by two daughters, Madonna Palladino of Minneapolis, Minn. and Michaelene Knudsen of Hermann, Mo., and one son, Erik Palladino, also of Hermann, Mo. He was preceded in death by his parents and sisters, Joan Anderson and Shirley Shawhan, and infant daughter, Michelle Theresa Palladino. Private family services will be held at a later date.
