Born in 1890, he was brought up in a very orthodox Brahmin family and he soon found himself in the epicenter of the freedom struggle from British rule. He courageously started displaying his social responsibility by educating and initiating Dalits (untouchables) into Brahminhood much to the fury of the elders in the community. When he showed no signs of listening to their advice, Krishna was ostracized from his community. It was a huge deal, but Krishna was undeterred.
He continued his service for the untouchables through the Sabari Ashram that stands even today, which is committed to the cause of educating Dalits. Mahatma Gandhi knew and adored Krishna and always paid him a visit during each of his tours to southern India. There are anecdotes which mention an incident when Krishna saved Gandhiji from riots by stopping a train and taking Gandhiji to a safe place before the train reached the station.
“One among the visits by Gandhiji was on March 18,1925. Gandhiji had reached the Sabari Ashram as a part of a campaign against untouchability. There was opposition to Gandhiji from some quarters and they had planned to stage a black-flag demonstration at the Olavakkode railway station. Krishnaswamy Iyer came to know of the demonstration and he gathered people to wave red flags and stop the train at Akathethara,’’ said Ramaswamy. Subsequently, Gandhij, along with Krishnaswamy Iyer, cut through paddy fields and walked to the Sabari Ashram.
Krishnaswamy Iyer was also active in the Vaikom and Guruvayur temple entry agitations.
