M. Raghava Iyengar

His father was Sadavadhaanam Muthuswamy Iyengar, a Tamil Poet in the court of Ponnuchami Thevar, the brother of the king of Ramnad, Muthuramalinga Sethupathi II.

[1] He also wrote Nootrettu Thiruppathi Agaval which lists out all the 108 Sri Vaishnava Divya Desams along with Purana Sthalams.

Mu Raghava Iyengar was a leading member of Madurai Tamil Sangam and helped edit the magazine Senthamizh (செந்தமிழ்) between 1905 and 1910.

[2] For his scholarly contributions, Mu Raghava Iyengar was granted the title of "Rao Sahib" in 1936 by the government.

Iyengar contributed scholarly treatises to magazines like செந்தமிழ் (Senthamil), கலைமகள் (Kalaimagal), தமிழர் நேசன் (Thamizhar Nesan), ஸ்ரீவாணி விலாசினி (Srivani Vilasini), கலைக்கதிர் (Kalaikathir), அமுதசுரபி (Amuthasurabhi).
