Baron Albert von Schrenk Notzing (1862-1929) was a German aristocrat and practising physician whose private wealth gave him the means to undertake an extensive programme of psychical research. He concentrated on physical phenomena, particularly on ectoplasmic materialisations, and his carefully-controlled experimental techniques put his results beyond all reasonable criticism. He worked with the well-known materialisation mediums of the time, Eusapia Palladino, ‘Eva C.’ and the Schneider brothers. His description of his work remains the most detailed account of the experiments of the time, and was published as:

Schrenck Notzing, Baron Albert von (1920). Phenomena of Materialisation. A contribution to the investigation of mediumistic teleplastics. Kegan Paul, Trench, Trubner & Co., London. Translated by E.E. Fournier d’Albe (First published in German as Materialisations - phaenomene, Reinhardt, Munich, 1914).

This book, together with those of Juliette Bisson and Gustave Geley, form the most detailed evidence available for the reality of ectoplasmic materialised forms. See also:
