On 16.6.1886, Dasaridas was born at Sivakasi in Ramanathapuram District, as a first child in a wealthy family from the Maruthuvar Community. His parents were Mr.Subbaiah and Mrs.Gnanambal. Dasaridas Later to be known as "Thiyagi Viswanatha Doss". He came under the tutelage of Sankaradas Swamigal. He is one of the earliest artistes to have used the Tamil stage to arouse the patriotic fervour through his messages vide drama and songs, he was the first Indian who had shown to the our country that one can convey the message of struggle for freedom through drama and songs. It was a meeting with Mahatma Gandhi that led to Viswanatha Doss involving himself actively in the freedom struggle. Invited to sing at the meetings of Mahatma Gandhi during his visit to Tuticorin in 1911, Viswanatha Doss was drawn into the freedom movement by Gandhiji who was captivated by his voice. Doss accepted the offer and soon took to wearing khadi. Not only did wear khadi, he also ensured that the character he was playing on stage too wore khadi. It was thus not uncommon to see him act as Lord Muruga in Valli’s stage play dressed in Khadi or as Kovalan in Kannagi’s play wearing khadi. This idea of using the stage to stoke the fire of patriotism gained momentum and soon it became common sight to see characters in plays such as Kovalan, ValliThirumanam, Harischandra Mayana Kandam being staged by various other troupes too singing patriotic songs on stage. Viswanatha Doss’s own theatre group, the "Shanmukanandam Drama Troupe" travelled to places such as Singapore, Burma, Malaysia and Sri Lanka, and spread the message of the movement through his plays and songs.

His active participation in the freedom struggle meant that he was never far away from trouble. In the place of Kanniseri, Police had given objection that Congress should not conduct any meetings. That time Thyagi Viswanathadas along with Pasumpon Muthuramalinga Devar went and gave a brave speech and on seeing the big crowd for their meeting police left the spot. It was common occurrence for the police to arrive at the venue where Viswanatha Doss was performing to arrest him as soon as he sang the songs propagating the freedom movement. Legend has it that he was arrested 29 times in the 29 years since he first met Mahatma Gandhi in 1911. It is also said that in one case where he was being tried for treason against the Crown, appearing for him was V.O.Chidambaram, the famous "Kappalottiya Thamizhan". On another occasion, it was Muthuramalinga Thevar who bailed him out after he was arrested in Ramanathapuram for singing songs arousing the patriotic fervour. Given his dedication and passion for the stage and the freedom movement, it was in a way fitting that his end came on stage.

When the Tamil patriotic song "Vellai Kodi Parakkuthadi Pappa" sung by Thyagi Viswanathadas, a round of applause will be there by the audience. On 1.1.1941 it was announced by posters all over the Madras city that Thyagi Viswanathadas will participate in a drama in four roles like "Velan, Vedan, Valayarkaran, Virutthan" etc..
