Hemachandra
Appearance
Hemachandra Suri (हेमचन्द्र सूरी) (correct Sanskrit spelling Hemacandra Sürí) (1089 -1172) was one of the greatest scholars of his time. He wrote on many subjects: grammar, philosophy, tradition, and contemporary history.
One of his best known works is the Tri-shashthi-shalaka- purusha-charitra, the lives of the 63 illustrious persons in Jainism. After having written this, he composed an appendix to it (hence called "Parishista-parvan"). This appendix, also called "Sthaviravali-charitra" is actually itself a text of considerable value.
Hemacandra, following the earlier Gopala, presented what is now called the Fibonacci series around 1150, that is at least 50 years before Fibonacci.
