Walt Whitman: The Making of the Poet

Clapp became Whitman's champion for a while. Clapp's influence helped make Whitman known and "located him on the margin of literary respectability." Clapp published reviews of Whitman's work and "nursed controversies and kept Whitman in the public eye as a radical new voice."

Clapp edited The Saturday Press until it ran out of money.

Zweig writes that, "In the evenings" during 1860 and 1861, Whitman "was mostly at Pfaff's with the crowd of drinkers he would soon be writing to from Washington: Hugo Fritch, Nat Bloom, Charlie Saunders, and others" (325).
