Who was Joseph Thomson?

Answer 1

Joseph John Thomson, or J.J. Thomson, was a British physicist. He received the Nobel Prize in Physics in 1906.

The prize was for his extensive research which was part of the process of discovering the electron. He is usually said to have discovered the electron, but it is more accurate to say he characterized and extended the experimental phenomena of the time which contributed to our understanding of the electron as a charged particle and a constituent of matter.

He is also known as the scientist who came up with the idea of the "plum pudding model" for the structure of the atom, a model later replaced after Ernest Rutherford (who had been a student under Thompson) discovered the nucleus.
