Frank Wigglesworth Clarke: American Geochemist
Education and Early CareerFrank Wigglesworth Clarke was born in Boston, Massachusetts in 1847. He graduated from Harvard University in 1867 and began his career as a teacher at the University of Cincinnati in 1874.
Work at the U.S. Geological Survey
In 1883, Clarke joined the U.S. Geological Survey as the Chief Chemist. He held this position for over four decades, until his retirement in 1924. During his tenure, he conducted extensive research on the composition of various geological formations and the Earth's crust.
Contributions to Geochemistry
Clarke's most significant contribution to geochemistry was his calculation of the average composition of the Earth's crust. This work established the concept of "clarkes," which represent the average concentrations of elements in different geochemical systems. Clarke also identified several new minerals, including uraninite.
Honors and Recognition
Clarke was a highly respected and influential figure in the field of geochemistry. He was elected to the National Academy of Sciences in 1909 and the American Academy of Arts and Sciences in 1911. The mineral clarkeite was named in his honor.
Legacy
Clarke's work laid the foundation for modern geochemistry. His research on the composition of the Earth's crust provided valuable insights into the planet's origins and evolution. His methods and ideas continue to be used by scientists today.
