Who invented the Indian harmonium?

The Indian harmonium, as we know it today, was developed in the 19th century, with significant contributions from European Musical Instruments. While it does not have a single inventor, its design evolved from the European harmonium brought to India by missionaries and colonial influences. Indian musicians adapted this instrument to suit local musical styles, leading to its widespread use in Indian classical and Folk Music. Thus, the Indian harmonium is a product of cultural exchange rather than the creation of a single individual.
