Thoothukudi Govindachari Raghavachari, also known by his initials TGR and the pseudonym Acharya, was an Indian filmmaker and lawyer who was active in Tamil cinema in the 1940s and 1950s.
A scholar in Sanskrit and English, he was a lawyer in the Madras High Court, and had in-depth knowledge of fine arts.
[3][4] Due to cinema being considered taboo in India at the time, Raghavachari worked anonymously and uncredited in films.
Nonetheless, the film became a success, and the two reunited for Apoorva Sagodharargal (1949), where Raghavachari was again credited as "Acharya" to maintain anonymity.
[6] He later began directing Kalyani (1952) for Modern Theatres, although cinematographer M. Masthan later took over after Raghavachari contracted tuberculosis; both men received director's credit.
