Biography

Joseph Paxson Iddings was born in Baltimore, Maryland on January 21, 1857, the son of a wholesaler in Philadelphia.[5] He received a master's degree from Yale College's Sheffield Scientific School in 1877.[6] Then he studied analytical chemistry at the University. Later, he transferred to Columbia University where he studied Geology under Professor John S. Newberry. He spent 1879-1880 at the University of Heidelberg, where he conducted petrographic research under the direction of Karl Rosenbush.

From July 1880 to 1895, he worked in the United States Geological Survey.[6]

Beginning in 1892, he lectured at the University of Chicago, where a Department of Petrology, the first of its kind in the world, was created especially for him. In 1908, he left the University and retired to his country house in Maryland, conducting his own research. He died unmarried and childless at his home in Sandy Spring, Maryland on September 8, 1920, from chronic nephritis.[6]
