Special Note:
The Turn Of The Century Electrotherapy Museum is honoured to
present three rare works on Lichtenberg Figures made by Danish
Scientist P. O. Pedersen.  We have obtained permission to publish
these papers from The Danish Royal Academy, who graciously sent
us uncut originals from 1919, 1922, and 1929.  These volumes are
at the museum, with PDF versions below.

We are grateful for the assistance of Danish Tesla Coiler Finn Hammer,
who has created many masterpiece Tesla Coils that included homemade
transformers and variacs that look better than those which can be
purchased new.  His amazing website is located at:

Thank You Finn, for giving us the opportunity to see and share these
wonderful documents.

Violet Rays Aids The Life Process
This peculiar little Violet Ray book is non-descript in terms of the manufacturer.  It came with
a Viracorp ("Violet Ray Corporation") Violet Ray.  The only sign a manufacturer name was
located on the bottle of ozone inhalant in the photo - Violetta / Bleadon Dun.
Perhaps this was done in an attempt to provide literature and avoid the issues of false claims?
Sterling Violet Ray and Booklet (1915) - Longoria Electrical
Laboratories, Cleveland Ohio

This booklet is unique in many ways.  It describes some basic repairs to the machine, and
mentions surface electrodes evacuated to the X-Ray degree.  Antonio/Anthony Longoria was
known in the 30s for trying to develop a death ray.   In the late 30s he began to develop special welders for thin materials and wire mesh.  In the early days he did work for Rogers Violet Ray.
Tesla Inspired Induction Coil:  2" hot flames from a Model T Coil ran
directly from 220/240V mains!  No electronic ignition here! No circuit

board!  No soldering!  No transistors!!

Rita and I had many adventures with a man we met across
the world in the Czech Republic.  His life was an
inspiration to everyone who met him.  He traveled the
world and found beauty and adventure in every place he
visited...including the Electrotherapy Museum.
