He was a soldier for the East India Company, joining in 1782 as a cadet. He became a brevet-captain in 1796, having been wounded in 1791 at Dooridroog, a hill fort near Bangalore, and Gadjnoor (not Doridroog and Gadjmoor, as stated in the Dictionary of National Biography ).
He married Elizabeth Lynn on 10 July 1794. She died on 13 December 1835 and was buried in the churchyard at Great Bealings on 19 December 1835.
While Major Moor lived in Great Bealings he experienced what he believed was a ghostly ringing of the servants' bells in the house. This began on 2 February 1834 and was alleged to have lasted fifty three days. He described his experiences in the book Bealings Bells, published in 1841.
The mysterious bell ringing was sensationalised by paranormal writers as evidence for poltergeist activity. However, the case was critically examined by Trevor H. Hall who concluded that Moor was not a reliable witness and had been duped by one of his servants playing a practical joke. Other writers have suggested that Moor was responsible for the bell ringing and the entire case was a hoax. Author Daniel Cohen wrote that there was "more than a suspicion" that Moor had played a joke on everyone and his book "may have been conceived as a gentle satire on investigations of other odd phenomena."
