Biographical sketch of Calvin Blanchard's brother, Rufus Blanchard (1821-1904)
[An entertaining snippet]
Should Blanchard† publish First Principles—and it is far from impossible (I prevented him from publishing Social Statics)—it would not only ruin the whole subscription project, but, by mingling your name with the gang of obscene, prurient, and scoffing authors whom he patronizes and advertises, would make it embarrassing for others.
† Calvin Blanchard, a disreputable publisher who kept a shop on Nassau Street, where you could buy any kind of book that your minister would frown upon—whether for free thought or for obscenity made little difference to this unsavoury Calvin. It is odd to find him wanting to publish Social Statics. Probably somebody had told him that the author was an “infidel” or a “positivist.” That would have been enough.
[from John Fiske, Edward Livingston Youmans: Interpreter of Science for the People, (New York: Appleton, 1895), 156-7]
