 Bernard Frank, a fellow forester, joined them later in the year; the men mailed an "Invitation to Help Organize a Group to Preserve the American Wilderness" to like-minded individuals.The invitation expressed their desire "to integrate the growing sentiment which we believe exists in this country for holding wild areas sound-proof as well as sight-proof from our increasingly mechanized life," and their conviction that such wildernesses were "a serious human need rather than a luxury and plaything".On January 21, 1935, the organizing committee published a folder stating that "for the purpose of fighting off invasion of the wilderness and of stimulating ... an appreciation of its multiform emotional, intellectual, and scientific values, we are forming an organization to be known as the WILDERNESS SOCIETY".
