David G. Croly

He wrote about "miscegenation" in an effort to promote antagonism to civil rights and authored a book on opponents of Reconstruction policies.

David Goodman Croly was born in Clonakilty, Ireland and educated at New York University.

In 1863, during the Civil War, he co-authored the anonymous pamphlet The Theory of the Blending of the Races, Applied to the American White Man and Negro, which tried to discredit the abolitionist movement and the Lincoln Administration by playing on racist fears common among whites.

[1] From 1870 to 1873, Croly published a journal called Modern Thinker which served as a vehicle for the positivist and Spencerian positions of himself and a small circle of colleagues, including John Humphrey Noyes.

[2] In 1872, Croly predicted the Panic of 1873, along with the failures of Jay Cooke & Co. and the Northern Pacific Railroad.
