In 1952, C. R. Subburaman died unexpectedly, which led to Ramamoorthy and Viswanathan joining to complete the background music for the films Subburaman was working on. They were introduced by
N. S. Krishnan, who knew them both fairly intimately and also their respective talents by then. T. K. Ramamoorthy, despite being an excellent musician with an orthodox Carnatic musical background, was a shy, modest and reserved person whereas M. S. Viswanathan was naturally talented, charming, forward and dynamic even if he lacked the similar background in Carnatic music. Ramamoorthy was older than Viswanathan by six years, but the placing of their names in
Viswanathan–Ramamoorthy team was agreed upon by both parties on the advice of Krishnan, who thereafter got the duo their first chance to score Krishnan's 1953 film,
Panam. The duo composed for over 100 films during the '50s and '60s, revitalising Chennai film music. The duo parted in 1965 and since then, they had composed for films individually. Although M.S. Viswanathan enjoyed a successful solo career, with over 700 films from 1965 to 2013, Ramamoorthy composed for only 19 films from 1966 to 1986. He was awarded an honorary doctorate, along with
M.S. Viswanathan, by the
Sathyabama Deemed University in September 2006. In addition,
J. Jayalalithaa being the
Chief Minister of
Tamil Nadu, conferred the
Thirai Isai Chakravarthy (; "Emperors of the Cine Music") title in August 2012 and presented it to him, along with 60 gold coins and a new car. ==Death==
