Reginald Aldworth Daly

from Wikipedia, the free encyclopedia

Reginald Aldworth Daly (born March 18, 1871 in Napanee , Ontario , † September 19, 1957 in Cambridge , Massachusetts ) was a Canadian geologist . He was a professor at Harvard University from 1912 to 1942 after serving as a mapping geologist for the Canadian International Boundary Commission .

He examined the rocks along a strip more than 600 kilometers long at the 49th parallel . From his findings during this work, he formulated a theory of igneous rocks , which he published in his 1914 work Igneous Rocks and Their Origin . He was an early proponent of Alfred Wegener's and Arthur Holmes ' continental drift theory, about which he published a book ( Out mobile earth ). In 1946 Daly published the collision theory of the formation of the moon .

In 1909 Daly was elected to the American Academy of Arts and Sciences , in 1913 to the American Philosophical Society and in 1925 to the National Academy of Sciences . In 1921 he became an Honorary Fellow of the Royal Society of Edinburgh . In 1929 he became a corresponding member of the Academy of Sciences of the USSR , in 1946 of the Académie des sciences in Paris and in 1950 a foreign member of the Royal Netherlands Academy of Sciences . In 1932 he was President of the Geological Society of America . He was awarded the Penrose Medal of the Geological Society of America in 1935 , the Wollaston Medal of the Geological Society of London in 1942, and the William Bowie Medal of the American Geophysical Union in 1946 . Crater on Mars and the moon ( lunar crater Daly ) and the rare mineral Dalyit are named after him, and his house in Cambridge (the Reginald A. Daly House is) today listed building as a National Historic Landmark .
