Villard's voltage booster appears in Fig. 1 on p. 31.

Greinacher's voltage doubler appears in Fig. 4 on p. 412.  He used chemical (electrolytic) rectifiers, which are denoted "Z" (Zellen, cells).

↑ In 1919, a year before Greinacher published his voltage multiplier, the German Moritz Schenkel published a multi-stage voltage multiplier.

↑ Jules Delon (1876-1941) was an engineer for the French company Société française des câbles électriques Berthoud-Borel . He used a mechanical rectifier, which was based on a rotating commutator (contact tournant ).
His apparatus was exhibited at the 1908 Exposition d'électricité in Marseille, France:  Georges Tardy (August 15, 1908) "Contact tournant de la Société  française des câbles électriques Systeme Berthoud-Borel", L'Electricien:  Revue Internationale de l'Electricité et de ses Applications, 2nd series, 36 (920) :  97-98.  (Article includes photograph of machine.)  The equipment was used to test insulation on high-voltage commercial power lines.
The operation of Delon's bridge rectifier is also explained (with schematic) in:  E. von Rziha and Josef Seidener, Starkstromtechnik:  Taschenbuch für Elektrotechniker (High-current technology:  A Pocket book for Electrical Engineers), 5th ed., vol. 1, (Berlin, Germany:  Wilhelm Ernst & Sohn, 1921), pages 710-711.
Delon's name and dates appear in:  Friedrich Heilbronner, Internationale Liste von Elektrotechnikern (2013), pp. 14-15.

Available on-line at:  Technica.  See also Delon's U.S. patents no. 1,740,076, no. 1,837,952, and no. 1,995,201.
