1947:
He opens an office near the corner of La Brea and Sunset Boulevard in Los Angeles, and tests the application of Dianetics among actors, directors, writers and others of the Hollywood community. These are the people who first receive the benefits of Mr. Hubbard’s revolutionary breakthroughs in the field of the mind.

1948:
L. Ron Hubbard accepts an appointment as a Special Police Officer with the Los Angeles Police Department and uses the position to study society’s criminal elements.

Moving on to Savannah, Georgia, he volunteers his time in hospitals and mental wards, saving lives with his counseling techniques.

With test cases and research material in hand, he travels to Washington, DC and compiles into final manuscript form the result of his sixteen-year investigation to determine the dynamic principle of existence. (The result of this work is published today as the book The Dynamics of Life.)

1949:
His as-yet-unpublished manuscript on Dianetics, which had been passed to a few friends for review, is copied and copied again until it circulates around the world. As a result of this enthusiastic response, he is urged by associates to write a popular book on the subject of Dianetics.

Late in the year, L. Ron Hubbard’s “Terra Incognita: The Mind,” the first published article on Dianetics, appears in the Winter/Spring issue of the Explorers Club Journal.
