James R. Wait

James R. Wait was a Canadian electrical engineer and engineering physicist.^[1]^[2] In 1977, he was elected as a member of National Academy of Engineering in Electronics, Communication & Information Systems Engineering for his contributions to electromagnetic propagation engineering as it affects communication and geophysical exploration.^[3]

Biography

Wait was born in Ottawa, Ontario, Canada, on January 23, 1924, received his BS (1948) and MS (1949) in engineering physics and his PhD (1951) in electrical engineering, all from the University of Toronto. Between 1948 and 1951, he worked for Newmont Exploration in Jerome, Arizona, where his research led to several patents in both IP and EM methods of geophysical prospecting. After a brief stint with the Defense Research Communications establishment in Ottawa, Wait first joined the National Bureau of Standards in Boulder, Colorado, and then NOAA; at each, he concentrated predominantly on theoretical aspects of radio-wave propagation.

Gertrude L Norman was his spouse, married in 1951 in Jerome AZ, deceased in 2010, Tucson, AZ. He had two Children, Laura H Wait, born 1954 in Ottawa Canada. She is a well known artist, living in Santa Fe. NM. Jim's son George, born in Boulder, CO in 1956, died in 2010 in Tucson, AZ. George had two children James and Carolyn. Jim has two great grandchildren.

He held numerous teaching and visiting scientist research positions at various prestigious universities and research establishments all over the world. In 1980, he was appointed professor of electrical engineering and geosciences at the University of Arizona in Tucson and in 1988 became one of the prestigious Regents' Professors. He died October 1, 1998, at his home in Tucson.^[2]
