*The army of those who have made at least one definite contribution to mathematics as we know it soon becomes a mob as we look back over history; 6,000 or 8,000 names press forward for some word from us to preserve them from oblivion, and once the bolder leaders have been recognised it becomes largely a matter of arbitrary, illogical legislation to judge who of the clamouring multitude shall be permitted to survive and who be condemned to be forgotten.'*- -- Eric Temple Bell:

##### Niels Henrik Abel (1802 – 1829)

Norwegian mathematician who died tragically young.

Made significant contributions towards algebra, analysis and group theory.

Best known for proving the impossibility of solving the general quintic in radicals (Abel-Ruffini Theorem).

##### Marius Sophus Lie (1842 – 1899)

**Sophus Lie** (pronounced **Lee**) was a Norwegian mathematician famous for his study of continuous transformation groups.

Such objects are now called Lie groups.
