Shoemaker, Eugene Merle (1928–97)

Astronomy

In 1952 he began to study Meteor Crater in Arizona, and became convinced that it and other terrestrial and lunar craters—which many believed to be volcanic—were impact features, especially after his discovery of coesite at terrestrial craters. In the 1960s he oversaw geological experiments on NASA’s lunar missions and helped to train the Apollo astronauts. With the American astronomer Eleanor Kay Helin, née Francis, and later with his wife, Carolyn (Jean) Shoemaker, née Spellmann (1929–2021), he began in the 1970s to search for near-Earth asteroids, potential causes of terrestrial impact craters, using the 0.46-m Schmidt telescope at Palomar Observatory. In addition to asteroids, Shoemaker discovered many comets, including Shoemaker–Levy 9, which demonstrated the effects of an impact on a gaseous body by crashing into Jupiter.

Geology and Earth Sciences

who founded the scientific study of impact cratering on Earth, the Moon, and on other solar system planets and their satellites, and who also pioneered the study of near-Earth comets and asteroids, often in collaboration with his wife Carolyn. This led him to recognize the importance of the cratering process in the history of the solar system. Shoemaker worked for the US Geological Survey (USGS) from 1948 to 1993 then continued to serve as scientist emeritus. In the 1960s he established the Astrogeology Branch of the USGS and its centre at Flagstaff, Arizona. Studies of the Moon and other bodies lacking atmospheres led him to propose that their surfaces should be covered with a layer of ejecta he termed ‘regolith’, and that the age of a surface could be inferred from its cratering. In March 1993, Gene and Carolyn Shoemaker and David Levy discovered a fragmented comet close to Jupiter. The comet, named Shoemaker-Levy 9, collided with Jupiter spectacularly in July 1994. Gene Shoemaker died in a car crash in the Australian outback. He and Carolyn, who survived, had been on their way to study a crater.
