MARKS, Dr. Ronald L. died May 2, 2017 at the age of 82 in Tucson, AZ. He was born in Avis, PA to William and Miriam (Strunk) Marks. Ron was the youngest of two older brothers, Bruce of Tucson and William Jr., deceased, of Jersey Shore, PA. Ron was married June 10, 1956 to Carol L. Cook of Dale, PA. Their happiness together began at the 1952 Thanksgiving Dance at Lock Have State Teachers College where they were both members of the freshman class. Ron and Carol were blessed with three wonderful daughters, Linda who predeceased her parents in 2010, Mona Croy of Aurora, OH and Sara McCarthy of Ashburn, VA. The three daughters provided their parents with five grandchildren, all of whom, according to their Grandpa could run faster, jump higher and spelled more words than any other child in the world. Ron and Carol began their careers as educators in Bradford, PA., Ron in chemistry and Carol in elementary education. Ron furthered his chemistry education at The Pennsylvania State University (M.ED., Ed.D.), Bucknell University, and Brown University. He loved teaching his students the subject of chemistry in the classroom and in the laboratory. Ron taught two years at Bradford, Pa High School, 28 years at the Indiana University of Pennsylvania, and nine years at the University of Arizona. He has published in both chemistry education and inorganic chemistry. Amongst his several awards was a Faculty Teaching Chair from the Commonwealth of Pennsylvania in 1978. Since his retirement in 1996, Ron and Carol have travelled and fished extensively; but, their love of family was always most important. A lifelong Lutheran, Ron was a member of the Tanque Verde Lutheran Church where a Memorial Service will be held on Monday, May 8, 2017 at 10:00 a.m. Arrangements by ADAIR FUNERAL HOME, Dodge Chapel.
