Mathematician:Pierre-Simon de Laplace

Mathematician
French mathematician and astronomer whose work greatly influenced the development of the mathematics governing astronomy.

Pioneered the field of mathematical physics. Considered himself to be the greatest mathematician in France.

Known within his lifetime as "the of France".

Often criticised by those who believe that his apparently insincere political views, and tendency to change sides to maximise his personal advantage, are a character flaw.

Others believe that his generous spirit, and willingness to help and encourage younger scientists, are of greater importance.

 * Laplace is the great example of the wisdom of directing all of one's efforts to a single central objective worthy of the best a man has in him.
