Thomas Brennan Nolan

Thomas Brennan Nolan (May 21, 1901 – August 2, 1992) was an American geologist who was director of the United States Geological Survey (USGS) from 1956 to 1965.The mineral nolanite is named in his honor. He was generally known as Tom Nolan.

Nolan was born in Greenfield, Massachusetts in 1901.

He was educated at New Haven, Connecticut then studied Metallurgyat Yale University, graduating with a BS in 1921. He continued studying at Yale and received a PhD in Geology in 1924. After training for the Civil Service he joined the US Geological Survey,

After Director William Embry Wrather retired because of illness and age in 1955, Assistant Director Thomas B. Nolan became the 's (USGS) seventh director in January 1956. During his 11 years as Assistant Director, Nolan had many times and for extended periods served as Acting Director so no transition period was needed. Nolan believed that geologists, because of the unique requirements imposed on them by their science, should expand their fields of interest from individual problems and "participate actively and authoritatively in the matters affecting the whole country." Until September 1965, when he resumed his research in Great Basin geology, Nolan pushed, prodded, and led the Survey to a broadened and intensified commitment to basic research, to the advancement of geology in the public service, and to the prompt publication of Survey results. As Assistant Director, he had also served as the Interior Department representative on the Interdepartmental Committee on Scientific Research and Development, on the Scientific Advisory Committee on Specialized Personnel to the Selective Service Committee, and on the Advisory Board on Education of the National Academy of Sciences, and had been president of the Society of Economic Geologists and the Geological Society of America (1961).

As Director, his professional responsibilities outside the Survey were still further extended to service as vice president and president of the Geological Society of America, as vice president of the International Union of Geological Sciences, and on committees advisory to university geology departments. In 1956, the Geological Survey began an evaluation of the effects of underground nuclear explosions at the Atomic Energy Commission's Nevada Test Site; that program was expanded to study the geologic and hydrologic conditions affecting the peaceful uses of atomic energy and the disposal of radioactive wastes.

In December 1958, Director Nolan, speaking at the meeting of the American Association for the Advancement of Science, remarked that the early work of the Geological Survey had been characterized by a transition from exploration of a geographical to an intellectual frontier, but demands by younger scientists for studies of the geography of outer space might soon inaugurate a new cycle in the history of the US Geological Survey.

In 1959, the Survey compiled a photogeologic map of the Earth's satellite, the Moon, and began studies of tektites and impact craters. On May 25, 1961, President John F. Kennedy proposed as a goal "landing a man on the moon and returning him safely to earth" before the end of the decade, and in 1963, the US Geological Survey, in cooperation with the National Aeronautics and Space Administration, began to train astronauts in geology and to investigate and evaluate methods and equipment for geological and geophysical exploration of the Moon.

He died in Washington D. C. on August 2, 1992.

He was married to Mabel ("Pete") Orleman (d.1983). They had one son.
