Born in Calcutta, he obtained a diploma from the Government College of Arts & Crafts there in 1959. He worked with various media before settling on a self-innovated form of tempera. His works are mainly in small format and are best appreciated at close quarters. Although he rarely travels out of Calcutta, Pyne has participated in numerous exhibitions, including the First International Triennial, New Delhi (1968), the Paris Biennial (1970), the Second International Triennial, New Delhi (1971), and many others in both Europe and Asia. He is the recipient of the Calcutta Art Society Award (1956), the Birla Academy of Art and Culture Award (1973) and the Shiromani Purashkar (1985). Pyne's works can be seen in the National Gallery of Modem art, New Delhi, the Academy of Fine Arts, Calcutta, the Lalit Kala Akademi, and in various private collections in India and abroad, including that of Sir Yehudi Menuhin.
