S. D. Somasundaram

. After his graduation, S.D.S worked as an assistant engineer in public works department.

Thiru S.D.S began his political career as an activist of the Dravida Kazhagam in 1947 and joined the DMK when the late C.N. Annadurai floated the party in 1949. He was first elected to parliament from the Thanjavure lok sabha constitutency in Tamil nadu in 1967 after defeating former president R.V. Venkataraman. He was re-elected from the same constituency in 1971 and 1977.

He was one of the first to come out of the DMK along with MGR and was considered by the AIADMK middle and lower-level workers as a simple man who mixed with them easily and had a fairly clean record. MGR took the activities of SDS very much close to heart. He resigned his MP post in 1977 and was nominated to the now-defunct legislative council.

Thiru S.D.S was an able parliamentarian and served as a Member of the Joint Committee on Salaries and Allowances of Members of Parliament during 1971-72, Committee on Private Members’ Bills and Resolutions during 1973-74; House Committee in 1977 and General Purposes Committee during 1977-78.. He was the first person to question MGR about the widespread corruptions during his term as chief minister. As a result of differences, that existed between him and MGR, he decided to quit AIADMK and floated his own party “ namathoo Kazhagam".

Later he quickly folded his new party and returned to the AIADMK, to be in dr. J. Jayalalitha's camp and served as revenue minister from 1991-1996. He was a pioneer in conducting the 8th Tamil world conference at Thanjavur during his tenure as revenue minister. Due to differences of opinion with Dr. J.jayalalitha, he quit AIADMK again and floated another party called “ puratchi thalaivar aiadmk”.

Thiru S.D. Somasundaram died on 6th December, 2001 at Chennai, at the age of 71.
