International New Thought Alliance, founded in London, England, in 1914 by renaming the National New Thought Alliance (founded in 1908) which had been formed by renaming the
World New Thought Federation (founded in 1905), which had formerly been the
New Thought Federation (founded in 1900); upon INTA's creation it also absorbed the
International Metaphysical League (founded in 1900), which was the international wing of The Metaphysical Club (founded in 1872); thus at the time of its official "founding", INTA had an unbroken membership history that stretched back 42 years.[1]
The Metaphysical Club (defunct), founded in Boston, Massachusetts, by Rev. L. B. Macdonald, Dr. J. W. Lindy and Mr. Frederick Reed in 1895. This group, which is unrelated to a group of the same name at Harvard University organized by C.S. Peirce, Oliver Wendell Holmes and William James in 1872, was called "the first permanent New Thought Club" by
Horatio Dresser. This Metaphysical Club was absorbed into the
International New Thought Alliance in 1914.[1]
