K. M. Adimoolam trained at the School of Art and Craft in Chennai and was part of the Madras Art Movement of the 1970s. After completing a Diploma in Advanced Painting in 1966, he began to work on a series of black and white portraits of Mahatma Gandhi. He sketched almost a hundred drawings covering 60 years of Gandhi's life.
He was a brilliant draughtsman. His works are an artist's expression of freedom of expression. Adimoolam moved to an abstract style when he started painting in oil in the 1970s.
