John Munro Longyear (15 April 1850 – 28 May 1922), a noted developer of timber and mineral lands in the Upper Peninsula of Michigan became the central figure behind the Arctic Coal Company which surveyed and mined coalfields on Spitsbergen, now Svalbard, from 1905 to 1916. This company developed a settlement on Spitsbergen able to accommodate up to around 500 people which became known as Longyear City, now Longyearbyen, adjacent Advent Bay.[2]

Born in Lansing, Michigan, Longyear served as mayor of Marquette, Michigan in 1890–1891.[3] He was one of the founders, ca. 1890, of the Huron Mountain Club near Big Bay, MI. In 1906 he founded the Arctic Coal Company with long-time associate Frederick Ayer and several other small shareholders. John Munro Longyear was the main owner of the Arctic Coal Company with headquarters in Boston, USA. Longyear had visited Svalbard in 1901, and bought the Tronhjem Spitsbergen Kulkompani in 1906.

Store Norske Spitsbergen Kulkompani started as a consortium of Norwegian investors in 1916. It purchased the Arctic Coal Company's and Ayer and Longyear's lands and operations on Spitsbergen in that year. They went on to develop major coal-mining operations in the Advent Valley region and at Sveagruva, originally a Swedish coal-mining operation.

Longyear died in Brookline, Massachusetts. His wife was Mary Beecher Longyear,[1] née Mary Hawley Beecher.

Mr. And Mrs. LongyearEdit

Longyear Museum was founded by noted philanthropist Mary Beecher Longyear (1851 - 1931), who had been greatly benefited by Christian Science. Personally acquainted with Mary Baker Eddy, Mrs. Longyear began in 1911 to assemble a remarkable collection of documents and artifacts. She founded the Longyear Museum to provide future generations with facts rather than myths and legends about this religious leader.

Before moving to Massachusetts, Mary Longyear, her husband, John, and their children lived in Michigan’s Upper Peninsula, where John had amassed a fortune in timber and mining. Their home in Marquette, built in 1892, was an imposing stone mansion on the shores of Lake Superior (photograph above shows the house circa 1900).

In 1903, when the Longyears decided to move to Brookline, Massachusetts, Mrs. Longyear was reluctant to leave her beloved home. So her obliging and financially able husband arranged for the house to be disassembled and moved by rail — more than 1,300 miles — from Marquette to its new site in Brookline.

The Longyears were known for their philanthropy and were generous patrons of art, music, and education. They contributed to many institutions organized for benevolent purposes, including the extension of the teaching of the blind by the Braille system and the publication of the Bible in Braille.

Mrs. Longyear generously provided funds to purchase a portion of the land adjoining The First Church of Christ, Scientist, in Boston, known as The Mother Church. The land is now part of the Christian Science Church plaza on Huntington Avenue in Boston.

At a time when development threatened landmarks in the name of progress, Mrs. Longyear collected paintings, furniture, documents, photographs, and artifacts on the life and work of Mary Baker Eddy, including four houses in which Mrs. Eddy lived. (Two additional houses were donated to the Museum, and thanks to generous donations the Museum was able in 2006 to purchase two other former homes of Mrs. Eddy.)

After Mrs. Longyear’s death, her home was opened to the public as Longyear Museum. Here the collection was exhibited from 1937 to 1998, when the home was sold to build the new museum at 1125 Boylston Street in nearby Chestnut Hill. The former Longyear residence and its grounds are now the site of the condominiums known as Longyear at Fisher Hill.
