Pell, John


Mathematician and clergyman, born in Southwick, West Sussex, S England, UK. He studied at Cambridge, and was appointed professor of mathematics at Amsterdam in 1643, and lecturer at the New College, Breda, in 1646. Employed by Oliver Cromwell, he went to Switzerland in an attempt to persuade Swiss Protestants to join a Continental Protestant league led by England. In 1661 he became rector at Fobbing in Essex, and in 1663 vicar of Laindon. He is remembered chiefly for the equation named after him, and for introducing the division sign ("÷') into England.
