## Bio

John Wallis was an English clergyman and mathematician born 3 December 1616. Between 1643 and 1689 he served as chief cryptographer for Parliament and later the royal court, reading encrypted messages while advancing pure mathematics in parallel. He extended Cavalieri's method of indivisibles through interpolation and applied Kepler's principle of continuity to develop techniques for evaluating integrals—steps that edged toward the calculus Newton would formalize. He introduced ∞ to represent infinity and 1/∞ for the infinitesimal, symbols that stuck. He died 8 November 1703, recognized as one of the greatest intellectuals of early modern mathematics.
