Barringer Medal (1985) Robert Sinclair Dietz (September 14, 1914 – May 19, 1995) was an American scientist with the United States Coast and Geodetic Survey. Dietz, born in Westfield, New Jersey, was a marine geologist, geophysicist and oceanographer who conducted pioneering research along with Harry Hammond Hess concerning seafloor spreading, published as early as 1960–1961. While at the Scripps Institution of Oceanography he observed the nature of the Emperor chain of seamounts that extended from the northwest end of the Hawaiian Island–Midway chain and speculated over lunch with Robert Fisher in 1953 that something must be carrying these old volcanic mountains northward like a conveyor belt.

Early life and education

Born and raised in Westfield, New Jersey, Dietz graduated in 1932 from Westfield High School.

Career

In later work he became interested in meteorite impacts, was the first to recognize the Sudbury Basin as an ancient impact event, and discovered a number of other impact craters. He championed the use of shatter cones as evidence for ancient impact structures. He received the Walter H. Bucher Medal from the American Geophysical Union in 1971, the Francis P. Shepard Medal for marine geology in 1979, the Barringer Medal from the Meteoritical Society in 1985 and the Penrose Medal from the Geological Society of America in 1988.

Dietz was an outspoken critic of creationism, and was the faculty advisor of two student groups at Arizona State University in 1985, Americans Promoting Evolution Science (APES) and the Phoenix Skeptics. Dietz spoke on evolution and creationism at meetings of these groups, and debated creationist Walter Brown and Christian apologist William Lane Craig at Arizona State University.

Death

Dietz died in Tempe, Arizona.

Minor planet 4666 Dietz is named in his honor.
