Madhan Bob

S. Krishnamoorthy (19 October 1953 – 2 August 2025), professionally known as Madhan Bob, was an Indian actor and comedian, appearing in many Tamil films in supporting roles. Madhan Bob was known for his amusing facial expressions, laughter and protruding eyeballs, inspiration for which he took from Kaka Radhakrishnan. He appeared in the popular Sun TV comedy show Asatha Povathu Yaaru? as one of the judges.

Early life Madhan was named by his parents as Krishnamoorthy. He was born on 19 October 1953 as the eighth child in his family. Madhan insisted that he had sufficient time to engage in self learning by honing skills and mastering his craft and body language including self-hypnotism. He had revealed that he wanted to maximise the learning capacity from his younger days by plying his trade playing musical instruments in order to keep himself busy and occupied. He also learnt other facets such as yoga and heavyweight boxing. He also reportedly dealt with issues pertaining to stammer, but he himself redeemed himself from the stuttering largely due to his sound knowledge of self-hypnotism.

Career Madhan also ventured into different career paths including serving as a medical representative and then serving in as a sales officer for a reasonable stint. He later quit his job as a sales officer in order to embark on opportunities in music arena. He also crossed paths meeting veteran musicians S Ramanathan, Harihara Sharma and ‘Vikku’ Vinayakaram from whom he gained mentorship and guidance in order to learn the techniques of western classical and carnatic music. Madhan had spent devoted majority of his time committing himself to broadcast music shows, songs for advertisements, dramas, radio commercials and serials. It is also believed that by the time Doordarshan had commenced its operations in Chennai in 1975, he became the first individual to play guitar on the channel. He also once served as a mentor to esteemed renowned musician A. R. Rahman, which was also confirmed by the latter himself during the music composition and audio launch of the film Thenali (2000). He later pursued his career in acting, mainly in supporting roles and Madhan was a part of consecutive silver jubilee movies and hence he was nicknamed ‘sentiment artist' by the Tamil film fraternity.
