Kunhiraman was born on 25 July 1937 at Kuttamath in Hosdurg Taluk of Kanhangad in Kasaragod District of the south Indian state of Kerala.[3] After early schooling at the local schools in Kuttamath and Puthaott, he joined Raja's high school, Nileshwaram to pass the Secondary School Leaving Certificate examination in 1957.[4] A teacher at his school, by name Krishnan Kutty, encouraged him to pursue his artistic interests but he did not get encouragement from his family which forced him to flee home to Chennai where he studied sculpture at the Government College of Fine Arts, Chennai.[5] It was during his days here, Kunhiraman had the opportunity to come in contact with K. C. S. Paniker who was a faculty and later, the principal of the institution.[citation needed] After completing the course, he worked as a part-time teacher at Ethiraj College for Women from 1961 but when he received the Commonwealth Scholarship, he moved to England to study at the Slade School of Fine Art[1] in 1965; he spent three years at the school. On his return to Kerala, he undertook a number of assignments and in 1976, he was invited to head the department of sculpture of the College of Fine Arts Trivandrum; he would also serve the institution as its principal until 1978 when he was nominated as the chair of the Kerala Lalithakala Akademi; he would also chair the academy again in 2001.[3]
On his return to Kerala from Chennai, Kunhiraman was commissioned by the irrigation department of Kerala, on recommendation from K. C. S. Paniker,[7] for an art work to be installed at the Malampuzha dam garden and he created Yakshi, a 5.5-metre (18 ft) statue of a naked woman, sitting on the lawns; the sensuality of the sculpture drew protests from traditionalists.[5] Two years later, he was invited by the Greater Cochin Development Authority (GCDA) for two sculptures in the premises of their new office in Kadavanthra and he created Environmental Pieces and Mukkola Perumal, both concrete sculptures.[8] He also created a sculpture, Fertility at Ambalamedu premises of the Fertilisers and Chemicals Travancore. In 1990, he completed the Jalakanyaka (Mermaid), a 23-metre (75 ft) sculpture at Shankumugham Beach, in Thiruvananthapuram;[9] The beach also has another of his sculptures titled, Snake.[8]
