[edit] Biography

Milne was born in Liverpool, England and raised in Rochdale and Milnrow in Lancashire.^[2] He was educated at King's College London and the Royal School of Mines, afterwards working as a mining engineer in Newfoundland and Labrador. In 1874, he participated in a geological survey expedition to northwest Arabia.

[edit] Career in Japan (1875-1895)

Milne was hired by the Meiji government of the Empire of Japan as a foreign advisor and professor of mining and geology at the Imperial College of Engineering in Tokyo from 8 March 1876, where he worked under Henry Dyer and with William Edward Ayrton and John Perry. Partly from a sense of adventure and partly because he suffered from seasickness, he travelled overland across Siberia taking three months to reach Tokyo. In 1880, Sir James Alfred Ewing, Thomas Gray and John Milne, all British scientists working in Japan, began to study earthquakes following a very large tremor which struck the Yokohama area that year. They founded the Seismological Society of Japan and the society funded the invention of seismographs to detect and measure the strength of earthquakes. Although all three men worked as a team on the invention and use of seismographs, John Milne is generally credited with the invention of the horizontal pendulum seismograph in 1880.^[3] Milne's instruments permitted him to detect different types of earthquake waves, and estimate velocities.

[edit] Contributions to Anthropology

In addition to his work on seismology, from 1882 John Milne was also contributing to the world of anthropology. He helped develop theories on where the Ainu of northern Japan came from, and theories on the racial background of the prehistoric peoples of Japan in general. After having actually excavated for several years in the Omori shell mound, John Milne introduced the conception of the Koropok-guru race, racially linked with the Inuit. The word Koropok-guru came from an Ainu word meaning “the man under the rhubarb,” i.e. a small person. An Ainu legend concerning the existence of such a people seems to have been first reported by Milne. However, Milne believed that only in Hokkaidō were prehistoric sites of the Koropok-guru people. For northeastern Japan proper, he subscribed to the tradition which assigned prehistoric sites to the Ainu, who lived in pits and made stone implements and pottery. He considered the inhabitants of the Kurile Islands, Sakhalin and southern Kamchatka to be of a different race, though possibly one related to the Koropok-guru. He anticipated the work of later scientists who in actual materials recovered recognized different prehistoric cultures for Hokkaidō and northeastern Japan. ^[4] His first cousin William Scoresby Routledge related to him though his mother, Emma Twycross, was also an anthropologist. Along with his wife Katherine Pease Routledge they worked in the early twentieth century in both East Africa with the Akikuyu and on Easter Island.

[edit] Career in England (1895-1913)

After a fire on 17 February 1895 destroyed his home, observatory, library, and many of his instruments. Milne resigned his posts on 20 June 1895 and returned to England with his Japanese wife, settling at Shide Hill House, Shide, on the Isle of Wight, where he continued his seismographic studies. He was made a professor emeritus of Tokyo Imperial University.

Milne persuaded the Royal Society to fund 20 earthquake observatories around the world, equipped with his horizontal pendulum seismographs. His network initially included seven in England, three in Russia, one in British Columbia, three on the east coast of the United States, and one in Antarctica, eventually growing to total 40 worldwide. These stations sent their 'station registers' to Milne, where the data formed the basis of Milne's researches. For the next 20 years, Milne’s seismological observatory was the world headquarters for earthquake seismology.

In 1898, Milne (with W. K. Burton), published Earthquakes and Other Earth Movements, which came to be regarded as a classic textbook on earthquakes.

The need for international exchange of readings was soon recognized by Milne in his annual "Shide Circular Reports on Earthquakes" published from 1900 to 1912. This work was destined to develop in the International Seismological Summary being set up immediately after the First World War.

Milne died of Bright's disease on 31 July 1913 and is buried in St. Paul's Church, Newport.
