Details:
John S. Minary autographed typed letter signed dated June 28, 1993, on personal letterhead, addressed to researcher Bruce Campbell Adamson regarding George de Mohrenschildt, Shelter Rock Development Corporation, and allegations concerning CIA associations tied to de Mohrenschildt and related business ventures. The one-page letter is boldly signed in black ink, “John S. Minary,” and is accompanied by the original handwritten transmittal mailing envelope.
In the detailed correspondence, Minary responds to questions concerning his knowledge of George de Mohrenschildt and “Rock Shelter Company,” clarifying that the recipient had likely confused it with Shelter Rock Development Corporation, a company solely owned by CBS chairman William S. Paley. Minary states that he served as an officer and director of the corporation from the mid-1940s until its liquidation in the late 1960s. He further explains that during the early 1960s George de Mohrenschildt presented Shelter Rock with several oil and gas exploration ventures and that the company may have participated in one or two of them. Minary specifically recalls George visiting his office on at least two occasions.
Most notably, the letter directly addresses longstanding conspiracy allegations surrounding the Kennedy assassination era by firmly denying any CIA connection, stating: “Shelter Rock Development Corporation did not, as you put it, ‘have CIA agents,’ or any other connection or relationship with the CIA.” The correspondence represents a firsthand response to JFK assassination-related research involving George de Mohrenschildt and William S. Paley’s corporate interests.
Fine condition with standard mailing folds and light handling wear. Accompanied by the original mailing envelope addressed in Minary’s hand.
Provenance: From the personal archive of Kennedy assassination researcher Bruce Campbell Adamson.
John S. Minary was a prominent attorney, Dartmouth graduate, and longtime secretary and financial advisor to CBS founder William S. Paley.

Kennedy.
