### Wallis's *Treatise of Algebra*

First publication focusing on algebra

Mathematician John Wallis, perhaps best known as the inventor of the symbol ∞ for infinity and for his eponymous infinite product for π, also wrote about the history and development of algebra in his *Treatise of Algebra*. In the preface of this work, published in 1685, Wallis credited Thomas Harriot (1560–1621), William Oughtred (1574–1660) and François Viéte (1540–1603) as contributors to the development of algebra as a mathematical discipline.
