Today in History November 8 :Wilhelm Röntgen discovers the X-ray and wins the very first Nobel Prize in Physics.

Wilhelm Röntgen
November 8 is the 312th day of the year. There are 53 days remaining until the end of the year.

Today's Highlight in History:
1895 – While experimenting with electricity, Wilhelm Röntgen discovers the X-ray.

Wilhelm Conrad Röntgen ( 27 March 1845 – 10 February 1923) was a German credited as the discoverer of X-rays on 8 November 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 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.

Birthplace of Roentgen in Remscheid-Lennep

His Early Life and Education

Born on March 27, 1845 in the small town of Lennep (Rhine Province) in Germany; Wilhelm Conrad Roentgen was the only child of a cloth merchant. He was raised in the Netherlands because his family moved to Apeldoorn when he was still three. For his early education he went to a boarding school in Apeldoorn named, Institute of Martinus Herman van Doorn. He was not a sparkling student rather he was keenly interested in nature during his young years. In
1862, he joined Ambachts school; a technical school in Utrecht. There he got involved in a contrivance against one of his teachers and was expelled subsequently.

In 1865, he studied mechanical engineering at the Federal Polytechnic Institute in Zurich having failed to get admission in University of Utrecht lacking required credentials. There he flourished greatly under the influence of the teachers like Kundt and Clausius. He graduated from the University of Zurich and received his Ph.D. in 1869. In the same year, he assisted Kundt and followed him to Wurzburg and then to the University of Strasburg in 1873.

His Professional Career

In 1874 Röntgen became a lecturer at the University of Strassburg. In 1875 he became a professor at the Academy of Agriculture at Hohenheim, Württemberg. He returned to Strassburg as a professor of physics in 1876, and in 1879, he was appointed to the chair of physics at the University of Giessen. In 1888, he obtained the physics chair at the University of Würzburg, and in 1900 at theUniversity of Munich, by special request of the Bavarian government. Röntgen had family in Iowa in the United States and at one time planned to emigrate. Although he accepted an appointment at Columbia University in New York City and had actually purchased transatlantic tickets, the outbreak of World War I changed his plans and he remained in Munich for the rest of his career.

Discovery of X-ray Beams

On November 8, 1895, Wilhelm Röntgen stumbled on X-rays while experimenting with Lenard and Crookes tubes and began studying them. He found that if vacuum tube, used for experiments with cathode rays, was covered tightly with thin, black cardboard and placed in a darkened room, bright glow was observed during each discharge on a screen covered with fluorescent barium platinum cyanide (placed near the device). He realised that the fluorescence was caused by an agent which could infiltrate from within the vacuum tube through dark cardboard (impermeable to visible or ultraviolet radiation) to the outside of the set. He termed this agent as x-rays.

Nearly two weeks after his discovery, he took the very first picture using X-rays of his wife Anna Bertha's hand. When she saw her skeleton she exclaimed "I have seen my death!".

By developing the image of his wife's hand and analyzing the variable transparency as showed by her bones, flesh and her wedding ring. and also based on his subsequent research and experiments, he declared that X-ray beams are produced by the impact of cathode rays on material objects

He wrote an initial report "On a new kind of ray: A preliminary communication" and on December 28, 1895 submitted it to the Würzburg's Physical-Medical Society journal. It was the first written paper on X-rays. Röntgen referred to the radiation as "X", to indicate that it was an unknown type of radiation. The name stuck, although (over Röntgen's great objections) many of his colleagues suggested calling them Röntgen rays. They are still referred to as such in many languages, including German, Danish, Polish, Swedish, Finnish, Estonian, Russian, Japanese, Dutch,

In 1901 Röntgen was awarded the very first Nobel Prize in Physics. The award was officially "in recognition of the extraordinary services he has rendered by the discovery of the remarkable rays subsequently named after him".

Nobel Prize

Röntgen donated the monetary reward from his Nobel Prize to his university. Like Pierre Curie, Röntgen refused to take out patents related to his discovery, as he wanted mankind as a whole to benefit from practical applications of the same

Röntgen was married to Anna Bertha Ludwig (m. 1872, d. 1919) and had one child, Josephine Bertha Ludwig. With the inflation following World War I, Röntgen fell into bankruptcy later in life, spending his final years at his country home at Weilheim, near Munich.

 In keeping with his will, all his personal and scientific correspondence was destroyed upon his death Röntgen died on 10 February 1923 from carcinoma of the intestine.It is not believed his carcinoma was a result of his work with ionizing radiation because of the brief time he spent on those investigations, and because he was one of the few pioneers in the field who used protective lead shields routinely.
