Henry Falkenau (January 14, 1864 – January 1, 1907) of Chicago, Illinois was a musician, music critic and bibliophile who operated an antique book shop at 167 Madison Street, Chicago, Illinois specializing in Americana, first editions, as well as metaphysics.[1] He was also an early defender of Walt Whitman's poetry, taking a First Amendment stand against censorship soon after Leaves of Grass was declared obscene in 1882.
