Nagesh (born Cheyur Krishna Rao Nageshwaran; died 2009) was an Indian film actor, mostly remembered for his roles as a comedian during the 1960s. He is regarded as one of the most prolific comedians in Tamil cinema. He acted in over 1,000 films from 1958 to 2008, performing in a variety of roles as comedian, lead roles, supporting actor and antagonist. Nagesh's style of comedy was largely inspired by Hollywood actor Jerry Lewis. Similarities between Nagesh and Lewis earned Nagesh the sobriquet "Jerry Lewis of India".
Nagesh was born as Cheyur Krishna Rao Nageshwaran to Krishna Rao and Rukmaniamma. He was born in Dharapuram, now in Tiruppur district, Tamil Nadu. While his school records give his date of birth as 8 February 1931, and his passport reads 27 August 1933, according to his elder brother’s wife he was born on Maha Navami (Saraswati Pooja).
He left Dharapuram at an early age and moved to Madras city in search of a career. His roommates, the writer Vaali and director Sridhar, later became established themselves as prominent personalities in the Tamil cinema field. He worked as a clerk in the Indian Railways.
