K. S. Radhakrishnan is a prominent contemporary Indian sculptor celebrated for his expressive bronze figures. Born in Kerala, India, he studied at Kala Bhavana, Visva-Bharati University, where he trained under influential modernist sculptors Ramkinkar Baij and Sarbari Roy Choudhury. His distinctive elongated figures—often depicting his recurring characters Musui and Maiya—explore movement, balance, memory, and the human experience. His work has been exhibited and installed throughout India and internationally.
Two characters dominate much of his life's work: Musui and Maiya. The elongated male and female figures appear repeatedly in his sculptures, often dancing, balancing, leaping or seemingly defying gravity.
Musui was inspired by a real person. As a student, Radhakrishnan met an 18-year-old Santhal man named Musui who sat for a portrait. The encounter stayed with the artist and eventually inspired his recurring male figure.
Maiya was created as Musui's female counterpart. Radhakrishnan has treated the pair as complementary aspects of human identity and has described them as recurring alter-ego figures.
A major work stands at the Supreme Court of India. His monumental bronze Constitution, the Flourishing Tree (2018) is installed at the Supreme Court complex in New Delhi.
