[1] The antecedents of the International New Thought Alliance date back to the 1899 New England convention of the Metaphysical Club,[2] one of the first New Thought organizations,[3] formed in Boston, Massachusetts in 1895 by, among others, L. B. Macdonald, J. W. Lindy, and Frederick Reed.
The first public lecture sponsored by the club was an address by Julia Ward Howe.
[4] This convention led to the founding of the International Metaphysical League the following year.
The first International New Thought Alliance Annual World Congress was held here, with a variety of New Thought luminaries leading the organization, such as James A. Edgerton, Annie Rix Militz, Thomas Troward, and many others.
Throughout its history, other New Thought notables such as William Walker Atkinson, Clara Bewick Colby, Florence Crawford, Horatio W. Dresser, George Wharton James, Edgar L. Larkin, Orison Swett Marden, and Elizabeth Towne were involved in the INTA.
