Rao Sahib Saravanapperumal Vaiyapuri Pillai (12 October 1891 – 17 February 1956)[1] was a renowned lawyer and Tamil scholar.

In June 1940, the government of Madras Province appointed a committee headed by V. S. Srinivasa Sastri to frame general principles for coining words for scientific and technical terms in Tamil.

Vaiyapuri justified the decision as a necessity for promoting national integration and cited the poetry of Manonmaniam Sundaram Pillai.

The decisions of the committee were opposed tooth and nail by activists of the Madras Presidency Tamil Sangam and were eventually reversed after Sastri's death in 1946.

In his budget address, finance minister K. Anbazhagan said compensation would be paid to the legal heirs of the authors having regard to the number of books written by them, their social impact and literary value.
