1941-1945: 

On 29 March 1941 L. Ron Hubbard receives his Master of Sail Vessel license for “Any Ocean.”

On 2 July 1941 he is commissioned as Lieutenant (jg) of the United States Navy Reserve. With the outbreak of war in December 1941, Ron is ordered to Australia where he coordinates intelligence activities.

Returning to the United States in March, Ron takes command of a convoy escort vessel in the Atlantic, then a subchaser in the Pacific. He also serves as an instructor and chief navigation officer, and is selected to Princeton University’s Military Government School.

In early 1945, while recovering from war injuries at Oak Knoll Naval Hospital, Ron conducts a series of tests and experiments dealing with the endocrine system. He discovers that, contrary to long-standing beliefs, function monitors structure. With this revolutionary advance, he begins to apply his theories to the field of the mind and thereby to improve the conditions of others.

1946:

After discharge from the US Navy in February 1946, Ron returns to writing, although his primary thrust continues to be the development of a means to better the condition of men. To help support this research, he writes thirty-one science fiction, fantasy, western, mystery and detective stories over the next three years. A few of the titles included in his work at this time are: Blood on His Spurs, Ole Doc Methuselah, Killer’s Law, Hoss Tamer and The Obsolete Weapon.

1947:

Ron opens an office near the corner of La Brea Avenue and Sunset Boulevard in Los Angeles, where he 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 Ron’s revolutionary breakthroughs in the field of the mind.

With test cases and research material in hand, Ron travels to Washington, DC where he compiles into manuscript form 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.)
