He once
said he considered himself a scientific historian, one whose mission
in life is to relate geologic and planetary events in a perspective
manner. A modest statement coming from a legend of a man who almost
single-handedly created planetary science as a discipline distinct from
astronomy. He brought together geologic principles to the mapping of
planets, resulting in more than 3 decades of discoveries about the planets
and asteroids of the Solar System. He was a 1992 recipient of the National
Medal of Science, the highest scientific honor bestowed by the President
of the United States, then George Bush. His family, friends, former
students, and the scientific community are in shock as they hear the
news and feel the loss of "SuperGene."
Dr. Gene Shoemaker died Friday, July 18 (Australian Time) in Alice Springs,
Australia in a car accident. He was in the field, pursuing his lifelong
passion of geologic studies to help understand impact craters with his
wife and science partner, Carolyn Shoemaker. Carolyn survived the accident
sustaining various injuries.
A longtime resident of Flagstaff, Arizona, in 1961 Gene invented the
Branch of Astrogeology within the U.S. Geological Survey and established
the Field Center in Flagstaff in 1963. Retired from the USGS in 1993,
he has held an Emeritus position there and has been recently affiliated
with Lowell Observatory in Flagstaff. An incredibly diverse person,
he influenced science in numerous ways: most recently, in a decade-long
sky survey for earth-crossing asteroids and comets, culminating in the
discovery (with wife Carolyn and David Levy) of Comet Shoemaker-Levy,
which impacted Jupiter in 1994, giving the world of science a major
new insight into both the dynamics of comets and the planetary science
of Jupiter. He has spent numerous summers (Australian winters) exploring
ancient parts of the earth for records of meteorite and comet impacts,
resulting in the discovery of a number of new craters. In much of his
asteroid and comet work, Shoemaker collaborated closely with his wife,
Carolyn, a planetary astronomer. A close and devoted couple, their work
was recently featured in a 1997 National Geographic documentary "Asteroids:
Deadly Impact." They considered their work a "Mom and Pop" operation
and together they initiated the Palomar Planet-crossing Asteroid Survey
in 1973, and the Palomar Asteroid and Comet Survey in 1983.
Gene Shoemaker seems to have been a geologist from the day he was born
in Los Angeles, California, in 1928. He did not even need to complete
his higher education (B.S. and M.S., California Institute of Technology,
1947 and 1948; Ph.D. Princeton University after an interrupted career,
1960) before starting the practice of astrogeology that was to lead
him to the planets. He began exploring for uranium deposits in Colorado
and Utah in 1948, and these studies brought him geographically and intellectually
near the many volcanic features and the one impact structure on the
Colorado Plateau in the western United States, namely Hopi Buttes and
Meteor Crater. In the period 1957-1960, he did his classic research
on the structure and mechanics of meteorite impact. This work--including
the discovery of coesite (a high pressure form of silica created during
impacts) with E.C.T. Chao--provided the definitive work on basic impact
cratering. It was work that he continued throughout his life--both by
exploration of the earth--particularly in Australia--and the planets
by remote sensing and mapping.
A man of vision, he believed geologic studies would be extended into
space and in his early career he dreamed of being the first geologist
to map the Moon. During the 1960's he lead teams who were investigating
the structure and history of the Moon and developing methods of planetary
geologic mapping from telescope images of the Moon. A health problem
prevented his being the first astronaut geologist, but he personally
helped train the Apollo Astronauts and sat beside Walter Cronkite in
the evening news giving geologic commentary during the Moon walks. He
was involved in the Lunar Ranger and Surveyor programs, continued with
the manned Apollo programs, and culminated his moon studies in 1994
with new data on the Moon from Project Clementine, for which he was
the science-team leader.

Award, Texas Section of the American Institute of Professional Geologists,
awarded posthumously, 1997.
From 1962 to 1985, Shoemaker blended his astrogeology research for the
USGS with teaching at the California Institute of Technology (Caltech).
He chaired Caltech's Division of Geological and Planetary Sciences from
1969 to 1972. One of his doctorate students at Caltech, Dr. Susan Werner
Kieffer, remembers him as being one of the most unfailingly generous,
and intellectually honest mentors she has ever known. His colleagues
at the USGS remember a exceptionally brilliant, exuberant, vibrant man
and a warm human being whose angry antics over copy machines and loud
happy laughter rang down the hallways. I remember a meeting when a newcomer
to science overheard Gene's excited conversation and laughter at a meeting
and remarked "who is that loud guy?"--to which I replied that is the
"god of planetary geology" and we all know that gods don't whisper.
As with his persona, Gene Shoemaker's legacy will never be a whisper,
but a loud burst onto the realm of Science that will be sorely missed.
He is survived by his wife; his son, Patrick Shoemaker and wife Paula
Kempchinsky; his daughters Christine Woodard and Linda Salazar and her
husband Fred; and grandchildren, Sean and Adrian Woodard and Stefani
Salazar, and a sister, Maxine Heath.
