Many scholars consider François Viète the seminal algebraist of the 16th century. Although he worked in mathematics in his spare time and was regarded as an amateur mathematician, he has contributed numerous improvements, solutions, and other vital developments to mathematics. For example, Viète had a hand in the development of modern algebra by devising algebraic notation, using letters to denote quantities, both unknown and known. He also contributed to the theory of equations, and introduced algebraic terms, such as "coefficient," that are still used today. Among Viète's other significant mathematical accomplishments are: using algebra to solve longstanding geometrical problems; calculating to 10 places, an important accomplishment of his time; playing a role in the improvements brought by the development of Julian calendars; and having a public hand in the mathematical controversies of his era.

Viète was born in Fontenay-le-Comte...
