Colesworthey Grant (sometimes spelt Colesworthy; 25 October 1813 – 31 May 1880[1]) was an English artist, writer and pioneer activist against cruelty to animals in India. Teaching himself art and sketching, he produced numerous portraits of many early East India Company servants of influence in Calcutta which were published in the local periodicals of the time. He later became a professor of drawing. He founded the "Calcutta Society for the Prevention of Cruelty to Animals" in 1861 after seeing the sorry conditions especially of draught animals on the streets of Calcutta.
