ABSTRACT We present a transcription of what are among the earliest available notes detailing Ida Rolf’s ten-session series, as she taught it in the mid-1950s under the name of Postural Integrity and as preserved by Byron Gentry, DC, an early student. The notes were re-typed for clarity, with introductory comments added and an image from the archival originals. Rolf and Gentry became great friends, and over the years shared a regular and voluminous correspondence. We include a scan of a letter Rolf wrote to Gentry, less for content than as a document of their friendship and mutual regard.
