K. Pattabhi Jois (26 July 1915 – 18 May 2009) was an Indian yoga guru who developed and popularized the flowing style of yoga as exercise known as Ashtanga vinyasa yoga. In 1948, Jois established the Ashtanga Yoga Research Institute in Mysore, India. Pattabhi Jois is one of a short list of Indians instrumental in establishing modern yoga as exercise in the 20th century, along with B. K. S. Iyengar, another pupil of Krishnamacharya in Mysore. Jois sexually abused some of his yoga students by touching inappropriately during adjustments. Sharath Jois has publicly apologised for his grandfather's "improper adjustments". Source: Wikipedia (en)
