A famous British physicist Rutherford was born in New Zealand in 1871. He received his secondary training at Nelson college and graduated from the University of New Zealand in 1889. Four years later he got his M.A. degree (master’s degree) with a double first in mathematics and physics.
In 1895 Rutherford won a prize which took him to Cambridge University. At the Cavendish laboratory his ability was recognized at once. His earliest research there was a detector for electromagnetic waves.
In 1897 Rutherford worked upon the mobility of ions and related topics. He left Cambridge for Montreal. Later Rutherford continued his work at Cambridge on the radiation from radium and reported in 1899 that it is quite complex and consists of alpha rays and beta rays. Rutherford was one of the creators of the modern theory of radioactivity.
Rutherford won the 1908 Nobel prize in physics. His researches in radiation and atomic structure were basic to the later 20th century development in nuclear physics.
He died at Cambridge on October 19, 1937.
