Henry Palmer was born at Bangalore, British India, on 30 April 1838; the youngest son of John Freke Palmer, then a major of the 32nd Native Infantry, Madras Army, and Jane James, a daughter of John James of Truro, Cornwall, and sister of then Lieutenant Henry James, Royal Engineers. Jane died at Bangalore on 24 May 1838, less than a month after Henry's birth.[7][5]
He was commissioned as a lieutenant of the Royal Engineers on 20 December 1856 and studied for a year at the Royal Engineers Establishment, Chatham. In October 1858, he was assigned to British Columbia, Canada, as part of a survey mission. In addition to undertaking several exploratory surveys, he laid out trails, supervised road construction, and inspected road-works. He was commended for his efforts, and during his stay in Canada also contributed papers on British Columbia to the Royal Geographical Society in London. In November 1863, one month after marriage at New Westminster on 7 October, he and his 15-year-old Canadian wife, Mary Jane Pearson Wright (17 January 1848–10 January 1934), daughter of the Ven.Henry Press Wright, Archdeacon of Columbia, and Ann Nalder, sailed for England.
From 1864 and 1874 Palmer served with the Ordnance Survey of Great Britain. Palmer was well known not only as a soldier but also as a scientist. From 1874, he undertook various postings as a surveyor, civil engineer, and astronomer in New Zealand, Barbados, Hong Kong, and Japan. At some point before Palmer headed out for Japan, he and his wife parted. She returned to her native British Columbia where she lived for the rest of her life.
After retiring from the Royal Engineers in 1887, he settled in Japan, established a successful civilian practice in Yokohama, where he was hired by the Japanese government to develop designs for the harbor, Ōsanbashi Pier and the city waterworks.[8] He was also a frequent contributor of letters and articles to the Japan Times,Japan Weekly Mail and other newspapers and periodicals, and was also a correspondent for The Times. He also wrote a profusely illustrated guidebook to Japan, "Letters from the Land of the Rising Sun".
At some point around 1890, he remarried to a refined Japanese woman, Uta Saito, with whom he had a daughter.[1]
A bronze bust of Palmer was unveiled by the Yokohama Water Works in 1987 to commemorate the centennial of its foundation. The Yokohama Archives of History also held a special exhibition in his honor the same year.
