The signs for greater than (>) and less than (<) were introduced in 1631 in “Artis Analyticae Praxis ad Aequationes Algebraicas Resolvendas.” The book was the work of British mathematician, Thomas Harriot, and was published 10 years after his death in 1621. The symbols actually were invented by the book’s editor. Harriot initially used triangular symbols which the editor altered to resemble the modern less/greater than symbols. Interestingly, Harriot also used parallel lines to denote equality. However, Harriot’s equal sign was vertical (II) rather than horizontal (=).
