Bellur Krishnamachar Sundararaja Iyengar cut a mean figure in his old age, sporting a mane of white hair and wild eyebrows that fanned his forehead between the stiff line that was always drawn down the middle (a marking to denote his sect within Hinduism). But the father of modern yoga, as he was often called, is remembered with an outpouring of fondness and grief the world over after his death from kidney failure on Wednesday. The 95-year-old was largely responsible for putting yoga on the global map, making the ancient Indian discipline more accessible to people of all ages.
