John Kanzius

John S. Kanzius (March 1, 1944 – February 18, 2009) was an American inventor, radio and TV engineer, one-time station owner and ham radio operator (call sign: K3TUP) from Erie, Pennsylvania. He invented a method that, he said, could treat virtually all forms of cancer, with no side effects, and without the need for surgery or medication. He also demonstrated a device that generated flammable hydrogen-containing gas from salt-water-solution by the use of radiowaves. In the media this was dubbed "burning salt water". Both effects involve the use of his radio frequency transmitter.

Kanzius, self-taught, stated that he was motivated to research the subject of cancer treatment by his own experiences undergoing chemotherapy for treatment of non-Hodgkin's lymphoma. He died of B-cell leukemia with complications from pneumonia without seeing FDA approval and commercialization of his invention.

He was of Rusyn descent - his mother was Rusyn American.
