 John Pell (mathematician)

John Pell (1611–1685) was an English mathematician known for his contributions to number theory and algebra. He is best known for Pell's equation, which is a specific type of Diophantine equation of the form \(x^2 - Dy^2 = 1\), where \(D\) is a non-square integer. Although Pell's equation had been studied before his time, Pell made significant contributions to its resolution and analysis.
