James Johnston (1851 – November 1921) was a British missionary, early photographer, doctor and explorer. He created his own mission at Brown's Town in Jamaica. He took six Jamaicans to help him on his journey across central Africa from west to east to cross the continent and rediscover David Livingstone's mission. Johnston's book and photographs record the journey and his observations on many things but particularly overly ambitious missionaries. Johnston later created slideshows to market Jamaica to potential tourists.
