Dr. Hollis Dow Hedberg (May 29, 1903 – August 14, 1988; nickname: "El Doctor Hedberg") was an American geologist specializing in petroleum exploration. His contribution to stratigraphic classification of rocks and procedures is a monumental work which received universal acceptance. The firm he worked for, the Gulf Oil Corporation in Venezuela, trusted his findings and explored what had until then been uncharted territory. As a result, they reaped huge benefits from their petroleum findings. Hedberg taught at Princeton University from 1959 until his retirement in 1971. He was awarded the Mary Clark Thompson Medal by the National Academy of Sciences in 1973.〔(【引用サイトリンク】url=http://www.nasonline.org/site/PageServer?pagename=AWARDS_thompson )〕 In 1975 he was awarded the Wollaston Medal by the Geological Society of London. Hedberg won the Sidney Powers Memorial Award in 1963.〔(【引用サイトリンク】title=Sidney Powers Memorial Award )〕 ==Early life== Hollis Dow Hedberg was born on 29 May 1903 in Falun, Kansas. He belonged to a small Swedish community and his parents lived on the second floor of the house. At that time Kansas experienced the worst flood in its history. His father, Carl August Hedberg, born in Sweden came to the United States as a child of four. His mother, Zada Mary Dow, was of Scottish-English descent. His initial years were hard and he worked in the fields. He also developed a skill for whistling (which became his trait) while ploughing fields with the horses. He came from a musical family: his father played violin, his mother the piano, his brother James the viola, and he himself played the cello. They were all fond of reading books to each other.〔
