Benjamin Smith Lyman (11 December 1835 – 30 August 1920) was an American mining engineer, surveyor and amateur linguist and anthopologist.

Biography

Benjamin Smith Lyman was born in Northampton, Massachusetts. He graduated from Harvard University in 1855. After working briefly as a school teacher, he worked as an assistant to his uncle by marriage on a topographical and geological survey of Broad Top Mountain in Pennsylvania, which spurred his interest in geology and mining engineering. He went for a year's study at the Ecole Imperiale des Mines in Paris (1859-60), followed by a practical course at the Freiburg Mining Academy in Freiberg, Saxony (1861-62). Upon returning to the United States, Lyman opened an office as a consulting mining engineer in Philadelphia and worked on surveys from Pennsylvania to Nova Scotia, Arizona and California.

In 1870, Lyman surveyed oil fields in the Punjab for the Public Works Department of the government of British India, and developed a lasting interest in the Far East.

In 1872, Lyman was hired by the Japanese government to survey the coal and oil deposits of Hokkaidō and along the Sea of Japan coastline of Honshu. His survey identified the most promising coal fields for Hokkaidō's eventually successful coal industry as well as reporting on progress in the reclamation of waste land, the nature of the soil in various districts; the customs, physique, and folklore of the Ainu people; useful ores and stones; the development of hydraulic power; importation of foreign capital; and the advantage of cooperation with foreign concerns in the mining industry. He stayed on in Japan from 1873-1879 as chief geologist and mining engineer to the Meiji government. While in Japan, he educated many Japanese in western techniques for natural resource surveys, and published the first geological map of Hokkaidō in 1876. Many of Lyman's Japanese assistants became proficient surveyors and some of them distinguished geologists, although his relations with the Hokkaidō Colonization Office were often strained. Before leaving Japan, he encouraged his assistants to form the Geological Society of Japan and to publish a journal. He donated his house to the new society for use as its headquarters.

In his study of the Japanese language, Lyman noticed that a necessary condition for the voicing (technically "rendaku") of the initial obstruent of the second word in a compound is that the word contain no voiced obstruent in a later syllable. (A sufficient condition for predicting "rendaku" is not known.) This constraint has come to be known as "Lyman's Law".

After his return to the United States, Lyman returned to Northampton, and spent the next several years working on his reports, which he published at his own expense. He attended meetings of technical and scientific societies as well as the Oriental Club of Philadelphia, and held a reception each year on the birthday of the Emperor of Japan. Although he officially retired in 1895, Lyman made a journey to survey the coal lands near Mount Lantauan on Cebu in the Philippines, for a New York company building a railroad there in 1906-07. On the way, he visited his former assistants in Japan. He hoped to re-visit Japan on his return trip, but was prevented by a long bout with dysentery.

Lyman, a vegetarian for most of his life, published a scholarly cookbook of vegetarian recipes in 1917 at the age of 81. He died August 30, 1920, aged 84, in Cheltenham, Pennsylvania.

Many of his personal journals, books, maps and papers are preserved at the “Benjamin Smith Lyman Collection” at the University of Massachusetts at Amherst.
