Surendranath Kar (1892–1970) was an Indian artist and architect, known for amalgamating the Indian architectural style with western and eastern styles of architecture. Born in 1892 in the Indian state of Bihar, Kar did his primary learning of art under renowned Bengali painter, Nandalal Bose and Abanindranath Tagore, the nephew of Nobel Laureate, Rabindranath Tagore. Later, he joined Vichitra Club, founded by the Tagore family, as a teacher of art. In 1917, when Tagore set up Brahmacharyasrama, the precursor of later day Shantiniketan, he joined the institution and worked as an art teacher. Two years later, he moved to Kala Bhavana of Tagore as a faculty member.
Kar, who was a companion of Tagore in many of his overseas visits, used the exposure he received to western and eastern architecture, to evolve his own style and, later, designed many buildings for Shantiniketan. The Government of India honoured him in 1959, with the award of Padma Shri, the fourth highest Indian civilian award for him services to the nation.
Surendranath Kar died in 1970 at the age of 78.
