William P. Lonc  (May 5, 1930 – November 27, 2014) was a professor emeritus of physics at Saint Mary's University in Canada and also the co-translator and co-editor of the series The Jesuit Relations, working assiduously in translating over 64 historical works by Lucien Campeau and other French Canadian Jesuit sources into English.

Life
Jesuit Father William P. Lonc was born in London, Ontario, Canada on May 5, 1930, son of Gregory Lonc and Veronica Lewickie.

He studied physics at Sir George Williams University in Montreal, before he entered the Jesuit novitiate on Sept. 7, 1954. He followed the usual Jesuit education with the addition of physics and mathematics. He entered the Polish Province of the Society of Jesus but transferred to the Canadian Province a few years later.

In 1965 he received a doctorate degree in physics (Ph.D.), followed by  a licentiate in philosophy from Saint Louis University.

On June 1, 1968, he was ordained a priest in the Roman Catholic Church.

As professor of physics at Saint Mary's University in Halifax, he specialized in astrophysics and microwave technology. He wrote a high school textbook on radio-physics, which is still used today, and had served for several years as a visiting short-term teacher at Bellarmine College Preparatory in San Jose, California. Fascinated by amateur radio, he soon became an expert in it. In his capacity as a researcher, he was one of the few people to gain access to the environmentally sensitive Sable Island, off the coast of Nova Scotia.

He had a sabbatical year in 1990–1991, and spent it in Tucson, Arizona, with the Vatican Observatory team. He was dedicated to reflections on the relationship between science and religion in the modern age. When he achieved Professor Emeritus status in 1995, he was among the last Jesuit professors to retire from the university, which was under Jesuit administration from 1937 to 1970.

Since his retirement, he worked assiduously in translating and editing a series of publications pertaining to the Jesuit Missions in Canada, beginning with the mission at Port Royal (today's Nova Scotia) in 1611 and reaching the 1860s. Fr. Lonc's areas of specialization included the early history of the Society of Jesus in the Maritimes, in Quebec and in 19th century Ontario. Most of the material consisted of translations from French and Latin of letters, diaries, and Reports (Relations), including the French historical works by Lucien Campeau, and is therefore basic data for historiographers.

In his final years he served as chaplain to the Sisters of St. Joseph in Toronto. He died on November 27, 2014, at the René Goupil House, the Jesuit infirmary  in Pickering, Ontario, aged 85 years, having lived 60 years in religious life in the Society of Jesus.
