Well-known geophysicist and geological engineer T.R. (Tom) Gledhill of Toronto has passed away. He was 74.
Gledhill, whose father, T.L. Gledhill, was a renowned mining engineer, earned his bachelor of science degree from the University of Toronto in 1954 in mathematics and physics. Upon graduation, he joined the firm McPhar Geophysics, which specialized in airborne and ground geophysical instrumentation and survey systems in the 1950s and 1960s.
After several years with McPhar, Gledhill left to join Nucom, a company established by Stan Ward. McPhar developed a helicopter-borne electromagnetic system, which was the precursor to later heli-systems such as DIGHEM and Hummingbird. Gledhill subsequently joined American Metals as a staff geophysicist and was involved in numerous exploration programs using geophysics throughout the Maritime provinces and the Canadian Shield.
In the mid-1960s, Gledhill launched a geophysical contracting and consulting firm with several partners, but eventually he was the only principal. He expanded his services to encompass all aspects of exploration and evaluation, working with a broad range of mining companies.
Gledhill was one of the earliest members of the Canadian Exploration Geophysical Society (KEGS), and was active in various charitable organizations, including Scouts Canada.
The KEGS Foundation has opened a scholarship under Gledhill’s name and will accept donations under its KEGS Pioneers Scholarship initiative. For more information, e-mail Jerry Roth at jroth@stratagex.com.
Gledhill is survived by his wife of 50 years, Barbara, five children (Gledhill’s son Peter passed away in 1996), and 21 grandchildren.
