Rev. John Anderson Graham arrived in Kalimpong in 1889 as a representative of Young Men's Guild of Scotland to do missionary work in the small village of Kalimpong which had recently been annexed by the British from Bhutan after the Dooars War of 1864–1865. In only a few years after arriving in Kalimpong Mr. Graham had turned into a social reformer who aimed to find a solution to what contemporary observers at that time called the "poor white problem" of British India. The "poor whites" were unacknowledged mixed race children of British fathers and "native" mothers. Shunned by the British and the upper class Indians most mixed-race children ended up on city streets. Newspapers, administrators and commentators portrayed this as an acute problem that threatened existing social and racial hierarchies. One solution took the form of St. Andrew's Colonial Homes in Kalimpong, where the pure air of the Himalayas would assist in schooling "poor white" children into a useful workforce.
