when was the term x ray first used
X-ray German physicist Wilhelm Röntgen is usually credited as the discoverer of X-rays in 1895, because he was the first to systematically study them, though he is not the first to have observed their effects. He is also the one who gave them the name "X-rays" (signifying an unknown quantity[4]) though many others referred to these as "Röntgen rays" (and the associated X-ray radiograms as, "Röntgenograms") for several decades after their discovery and even to this day in some languages, including Röntgen's native German.

X-ray The first use of X-rays under clinical conditions was by John Hall-Edwards in Birmingham, England on 11 January 1896, when he radiographed a needle stuck in the hand of an associate.[26] On February 14, 1896 Hall-Edwards was also the first to use X-rays in a surgical operation.[27] In early 1896, several weeks after RÃ¶ntgen's discovery, Ivan Romanovich Tarkhanov irradiated frogs and insects with X-rays, concluding that the rays "not only photograph, but also affect the living function".[28]
Holy Roller Merriam-Webster traces the word to 1841.[3] The Oxford English Dictionary cites an 1893 memoir by Charles Godfrey Leland, in which he says "When the Holy Spirit seized them ... the Holy Rollers ... rolled over and over on the floor."[6]
