Herman LeRoy Fairchild

Herman Le Roy Fairchild (April 29, 1850 – November 29, 1943) was an American educator and geologist.

He located strand lines (beaches) and erosional surfaces, determined their altitude, and interpolated between them to show the extent of several large bodies of water.

A series of lakes was created as the Wisconsinan glaciation ended and ice sheets retreated during the latest Pleistocene and early Holocene epochs.

He taught at the University of Rochester for many years and founded the geology department there.

He co-founded the Geological Society of America (GSA),[1] served as its Secretary from 1891 to 1906 and President from 1912 to 1913.
