János Bolyai ( December 15, 1802January 27, 1860) was a Hungarian mathematician.

Bolyai was born in Kolozsvár, Transylvania, Austro-Hungarian Empire (today Cluj-Napoca, Romania). When he was 13, he had mastered the calculus and other forms of analytical mechanics, his father Farkas Bolyai giving him instructions.

GaussJohann Carl Friedrich Gauss (Gauss ( April 30, 1777 February 23, 1855) was a legendary German mathematician, astronomer and physicist with a very wide range of contributions; he is considered to be one of the greatest mathematicians of all time. His name, on reading the Appendix, wrote to a friend saying "I regard this young geometer Bolyai as a genius of the first order".

Biography Lobachevsky was born in Nizhny Novgorod, Russia. His parents were Ivan Maksimovich Lobachevsky, a clerk in a landsurveying office, and Praskovia Alexa had published a similar piece of work in 1829, but also a generalisation of this theory. So as we know, Lobachevsky published his work a few years earlier then Bolyai, but it contained only hyperbolic geometry. Bolyai and Lobacsevszkij haven't known each other or each other's works.

In addition to his work in geometry, Bolyai developed a rigorous geometric concept of complex numbers as ordered pairs of real numbers. Although he never published more than the 24 pages of the Appendix, he left more than 20000 pages of manuscript of mathematical work when he died. These are now in the Bolyai-Teleki library in Targu-Mures, Romania.

He was an accomplished linguist speaking nine foreign languages including Chinese and Tibetan. The Babes-Bolyai University in Cluj-Napoca is named after him.
