Nikola Tesla (Serbian Cyrillic: Никола Тесла) (10 July 1856 – 7 January 1943) was a Serbian American inventor, physicist, mechanical engineer, and electrical engineer. Born in Smiljan, Croatia , Austro Hungarian Empire, he was an ethnic Serb subject of the Austrian Empire and later became an American citizen.^[2] Tesla was born to a Serbian family in the village of Smiljan near Gospić, in the Lika region in Krajina, Croatia (then part of the Austrian Empire). According to legend, he was born precisely at midnight during an electrical storm.Tesla is best known for his many revolutionary contributions to the discipline of electricity and magnetism in the late 19th and early 20th century. Tesla's patents and theoretical work formed the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC motor, with which he helped usher in the Second Industrial Revolution. Contemporary biographers of Tesla have deemed him "The Father Of Physics" and "the man who invented the twentieth century"^[3] and "the patron saint of modern electricity.

In April of 1887, Tesla began investigating what would later be called X-rays using his own single node vacuum tubes (similar to his patent #514,170 ). This device differed from other early X-ray tubes in that they had no target electrode. The modern term for the phenomenon produced by this device is bremsstrahlung (or braking radiation). We now know that this device operated by emitting electrons from the single electrode through a combination of field emission and thermionic emission. Once liberated, electrons are strongly repelled by the high electric field near the electrode during negative voltage peaks from the oscillating HV output of the Tesla Coil, generating X-rays as they collide with the glass envelope. He also used Geissler tubes. By 1892, Tesla became aware of what Wilhelm Röntgen later identified as effects of X-rays.

In the early research, Tesla devised several experimental setups to produce X-rays. Tesla held that, with his circuits, the "instrument will [... enable one to] generate Roentgen rays of much greater power than obtainable with ordinary apparatus." He also commented on the hazards of working with his circuit and single node X-ray producing devices. Of his many notes in the early investigation of this phenomenon, he attributed the skin damage to various causes. One of the options for the cause, which is not in conformity with conventional x-ray production, was that the ozone generated rather than the radiation was responsible. He early on stated,

“	As to the hurtful actions on the skin [...] I note that they have been misinterpreted [...] They are not due to the Roentgen rays, but merely to the ozone generated in contact with the skin. Nitrous acid may also be responsible, but to a small extent.
—Electrical Review, 30 November 1895

Tesla's experiments were confirmed by others. Tesla later stated,

“	[...] I have not noted injuries which could be traced directly to this cause, though on several occasions burns were produced in all respects similar to those which were later observed and attributed to the Roentgen rays. This view is seemingly being abandoned, having not been substantiated by experimental facts, and so also is the notion that these rays are transverse vibrations.	”
