IDDINGS, Joseph Paxson.

(1857 – 1920)

(Born: Baltimore, Maryland, U.S.A., 21 January 1857; Died: Montgomery County Hospital, Maryland, U.S.A., 8 September 1920) American petrologist & mineralogist.

Iddings moved to Orange, New Jersey at age of 10. In 1877, he graduated from the Sheffield Scientific School of Yale University, where he became interested in mineralogy and petrology. He traveled to Europe, becoming a student from 1879 to '80 of Harry Rosenbusch [1836-1914] at the University of Heidelberg. Upon returning to America in 1880, he went to work for U.S. Geological Survey. There he helped survey the Eureka district of Nevada and Yellowstone National Park. Iddings accepted an appointment as professor of petrology at the University of Chicago in 1895, where he remained until 1908. Then Iddings retired to a private life of scholarship.

Scarce. The advance of petrology during the late nineteenth century is clear in Iddings textbook. Here the emphasis is on determining the mineral species that make up rock aggregates. The numerous illustrations show apparatus, diagrams and many excellent crystal drawings probably copied from Dana's Sixth Edition, which was also a Wiley publication.
