Today’s History Feature:

Prof. Wilhelm Rontgen

(Mar 27,1845 – Feb 10,1923)

💠German Physicist

💠Father of Radiology

His contributions…

🔸Wilhelm Rontgen was a Professor of Physics at Wurzburg University, Germany.

🔸One day, while he was conducting an experiment, he noticed the photographic plates near his equipment were glowing due to the mysterious rays emitted by the Cathode ray tube. That tube had a pair of electrodes. Because electricity was passed between the electrodes, the rays were emitted and appeared on the photographic plates.

🔸Through series of investigation conducted on 8th November 1895, Roentgen created a new ray and called as rays X for unknown.

🔸Subsequently, he took the X-ray photographs of metal objects and took the picture of his wife Anna bertha’s left hand with wedding ring.

🔸On seeing the X-ray image, Anna became horror-struck and exclaimed – “I have seen my death!

🔸In fact, his discovery of X-Rays created a great revolution in the fields of physics and medicine.

🔸In recognition of his incredible discovery, Prof. Roentgen was honoured with Rumford Medal of the Royal Society of London in 1896 and received the first Nobel Prize in Physics in 1901.

🔸Later, Prof. Rontgen donated his entire prize money to promote scientific studies and moreover he strongly refused to patent his own discovery.

🔸Unfortunately, Prof. Rontgen was affected by colon cancer and died at the age of 78.

🔸His Legacy…

🔅 X-rays or Rontgen rays.

🔅 Rontgenology – synonym for Radiology in North America.

🔅 Rem (rontgen equivalent man), a legacy unit of measurement of effective dose.

🔅 Element number 111 was named roentgenium (Rg) in his honour.

🔅 International Day of Radiology is celebrated annually on 8th November – the anniversary of the discovery of X-rays.

A Day to Commemorate

A Scientist Who Made the Invisible Visible
