Thomson was born in
Ayr, Scotland on 9 January 1854. He was by trade a
house painter. Eventually, the lodge members refused to accept his Masonic degrees from Scotland and also accused him, as a Mormon taking part in the
Temple endowment ceremony, of practicing a "clandestine" form of Masonry. Thomson claimed the AMF descended from an
African-American lodge in
New Orleans, and accepted blacks as members unlike the "regular" Grand Lodges of the time. He sold Masonic degrees by mail to "shopkeepers, workers and other people" mainly from Utah, who as Mormons were not eligible to become Freemasons under the
Grand Lodge of Utah. In 1918, Thomson dedicated a
Masonic temple. He also published a periodical entitled the
Universal Freemason, in which he attacked the Grand Lodge of Utah's policy of exclusion. The Grand Lodge of Utah protested Thomson's activities, and sent a letter to all Utah Masons warning them that AMF lodges were "clandestine, spurious, and fraudulent". ==Contacts with European "fringe" Freemasonry==
