Germany: Nacht Schatten, .
16mo. Hardbound in dust jacket. First German edition of this collection of essays. Presentation copy inscribed by Hofmann to fellow author and psychedelic researcher, Ralph Metzner on the occasion of Ralph's visit to Hofmann's home shortly after the conference celebrating his 100th birthday: "Fur / Ralph / in geboryen heit / der BL / Albert / 26.VI. 06." ("For Ralph / in the shelter / of BL"---a reference to his home near Basel.) A splendid association linking the man who discovered LSD to one of the major researchers in that field. Metzner co-athored several titles with Timothy Leary based on their groundbreaking psychedelic drug experiments at Harvard, and he went on to write The Ecstatic Adventure and other books on psychedelic drug experience. Hofmann's signature is uncommon, but meaningful association copies are rare. Very fine with Metzner's bookplate to front pastedown.
