Jacob Eugene “Jack” Gair, 75, an internationally known economic geologist who retired from the U.S. Geological Survey in 1987, died of cancer at his home in Kensington, Maryland, on January 1, 1998. Jack was widely recognized
for his research on iron deposits in the Upper Peninsula of
Michigan and in Brazil, and on volcanogenic massive sulfide
deposits of the central and southern Appalachian
Jack was born in Pittsfield, Massachusetts, and grew
up in Lee, Massachusetts, where he was active in the Boy
Scouts, attaining the rank of Eagle Scout. He served as a
B-24 pilot in the 8th Army Air Force in England during
World War II, flying 33 combat missions. Before and after
the war, he attended the University of Rochester, where he
played on the football team and was a member of Delta
Upsilon Fraternity. Jack received a B.A. degree in geology and English from the University of
Rochester in 1946 and was elected to membership in Phi Beta Kappa, the national honor society.
He earned a Ph.D. degree in geology from The Johns Hopkins University in 1949.
Jack taught geology at the University of Oregon from 1949 to 1952. He joined the USGS in
1952, devoting the ensuing 35 years of his career to studies of domestic and global mineral
resources. Jack’s first Survey work was in a USGS field office in Iron Mountain, Michigan,
where he studied iron deposits of the Upper Peninsula. From 1954 to 1956 he lived in Belo Horizonte,
Brazil, undertaking geologic studies of iron deposits in the Itabira district and training
Brazilian geologists in field and laboratory methods. From 1957 to 1968 he worked out of
USGS offices in Denver and Marquette (Michigan), where he continued research on iron
deposits of the Marquette and Iron Mountain districts in northern Michigan. Jack moved to the
Washington, D.C., area in 1968. He appraised iron resources in Turkey in 1969, and during the
1970s investigated tungsten deposits in the Hamme district of North Carolina. From 1971 to
1973 he served as Deputy Assistant Chief Geologist and Acting Chief of the Office of Mineral
Resources of the USGS. During the 1970s and 1980s he evaluated the potential for mineral
resources on Native American lands in the eastern and southern United States, in several
Wilderness Areas in Georgia and Tennessee, and in the Charlotte (North and South Carolina)
1° × 2° quadrangle. In 1975 Jack began studies of volcanogenic massive sulfide deposits of the
Appalachian Mountains region, chiefly in the Mineral and Gossan Lead districts of Virginia, and
in the Ducktown district of southeastern Tennessee; he continued these studies until his retirement.
In 1979 he assessed copper deposits in Egypt. From 1976 until 1984 he served as U.S.
representative to the highly successful IGCP Project 60 on massive sulfide deposits of the
Jack was the author of nearly 100 scientific papers, maps, and abstracts, an editor of several
volumes, a Fellow of both the Geological Society of America and the Society of Economic

Geologists, and a member of the Geological Society of Washington. He received the Meritorious
Service Award of the U.S. Department of the Interior in 1987.
Jack will long be remembered by his colleagues for his meticulous attention to detailed and
accurate descriptions of geologic features, and for his insistence that any interpretation was
inadequate unless it explained all observed features. His maps and reports on the Michigan iron
ranges, in particular, are a timeless contribution to knowledge of U.S. mineral resources.
Jack enjoyed photography and world travel, and was active in the Science and Religion
Group of the Cedar Lane Unitarian Church in Bethesda, Maryland. He was also an associate
member of the Woman’s National Democratic Club. Survivors include his wife of 53 years,
Peggy Lou Davis Gair; his daughter, Cynthia; his sons, Dan and Philip; his grandaughter, Aja;
and two brothers, David and Robert. Jack’s family, his many friends, and his geologic work
were the cornerstones of his life.
