I need a writer - Math Biography

The biographical sketch should contain information about the time period in which the person lived and worked, the major contributions of the person, and, if possible, any interesting (humorous?) anecdotal information. The paper will generally include information about the person, when and where they did their work, who influenced them, and who they influenced. Important: the written essay must contain and briefly explain a mathematical relationship, figure, or graph that is representative of the mathematician's contribution.
