Ron's research interests included, as well as structure and bonding, superacids (and, related, aprotic media of very low Lewis Basicity) and the cations that could be formed in them, fluorine chemistry and noble-gas chemistry. He authored or co-authored more than 380 papers, two first year textbooks, and several books on molecular geometry.
Among the many recognitions that he received were Membership of the Order of Canada, Fellowship of the Royal Society (London), Fellowship of the Royal Society of Canada, Fellowship of the Royal Institute of Chemistry, Honorary Fellowship of the Chemical Institute of Canada, and several honorary degrees. He retired from McMaster University in 1988 as an Emeritus Professor.
Outside of chemistry, Ron enjoyed Scottish country dancing, hiking, skiing and sailing. Many of his students will remember crewing for him in his Wayfarer dinghy, which he loved to race. He continued to sail, in keelboats (up to 36 ft.), well into his retirement, cruising around Lake Huron-Georgian Bay. He and his family had a love of adventure and travel; he spent sabbatical leaves in England, France, Germany, Switzerland, Australia, New Zealand, and India, and also visited many other countries.
Ron died on February 26 , 2021. He leaves behind his wife Marcelle, his daughters Ann and Lynn, and many friends. He was pre-deceased by his first wife, Madge.
