Mirza Reza Kalhor (fa|محمدرضا کلهر; – 1892) was a 19th-century Iranian calligrapher, known for his mastery of the Nastaʿlīq script technique.[1]
A member of the Kurdish Kalhor tribe of Kermanshah, he initially followed the typical tribal path, learning horsemanship and sharpshooting. He gained an interest in calligraphy as a child, and left the tribe for further training.[1] During his career, he introduced several innovations to Nastaʿlīq calligraphy, changing both the aesthetics and mechanics of the technique.[1]
Kalhor modified and adapted Nastaʿlīq to be easily used with printing machines and newspaper lithography, which in turn helped wide dissemination of his transcripts.[1] [2] He also devised methods for teaching Nastaʿlīq and specified clear proportional rules for it, which many could follow.[1]
He died of cholera in Tehran at age 65, having sired nine children and taught many calligraphy students, several of whom went on to become notable in their own right.[1] He was buried in Ḥasanābād cemetery.[1]
