Thomas Burton Kinraide (1864-1927) (Famous Works Thomas Kinraide)


Thomas Burton Kinraide (1864-1927) was an electrician and inventor of a high-frequency x-ray coil, commonly known as the Kinraide Coil.


By using glass plate negatives in a spark gap between the poles of his coil, he was able to capture some stunning electrical discharges.


Positive discharges produced fern-like branching which he called “filiciform”. Negative discharges produced a softer, feathery-like images which he called “plumous”.

With his coil and techniques, he was able to capture images containing both positive and negative discharges which combined at the base of the discharge.
