Charles Glover Barkla

1877-1944
Scientist and Nobel Prize Winner


Barkla was born in Widnes near Liverpool, and he was educated at Liverpool University.   After some years of research at Cambridge, Barkla returned to Liverpool in 1902 and devoted himself to the study of röntgen radiation. Barkla was a pioneer in the study of the character of X-rays. He showed that every element radiates a characteristic form of X-rays specific for the element. Barkla also confirmed that this radiation has a definite permeability, specific for each element.   Barkla won the 1917 Nobel Prize in Physics.

In 1977 he was honoured by the Swedish Post Office with a commemorative stamp.
