From the report of the 2nd IVU Congress, Manchester, England 1909:

Mr. Scott spoke for the "Battle Creek Idea," and explained how from very small beginnings Dr. Kellogg's movement had now grown to what one might fairly call gigantic dimensions. Vegetarianism is not their only tenet, but it is a very important one.

The full text of this talk is available and should be added here later.

The report of the 4th IVU Congress, at The Hague, The Netherlands, 1913, listed the papers presented to the Congress, including:

Dr. Kellogg, of BattleCreek (U.S.), "Recent Scientific Discoveries confirming the Principles of Natural Food Reform."
