To fund that research through the Great Depression, Ron embarked upon the first leg of a fifty-year literary career. By the mid-1930s he was among the most widely read authors in the fabled heyday of American pulp fiction. He also scripted several memorable screenplays in Hollywood’s Golden Age, and is still remembered for his work on various box office blockbusters and a classic Clark Gable film.

But never losing sight of his primary quest, he continued his mainline research with far-flung expeditions to primitive lands. He would eventually study 21 races and cultures while searching out an underlying “common denominator of existence” upon which to build a workable philosophy for the betterment of Man. In early 1938, he isolated that common denominator as Survive!

That survival was a key motivation within all living things was not a new idea. That all life was ultimately and only attempting to survive—this was entirely new. Ron originally presented this discovery in a manuscript entitled “Excalibur.” Although he eventually chose not to publish the work as it lacked any actual method for improvement, here nonetheless was the philosophic yardstick with which to align all further research.

In recognition of his exploratory achievements through these years, 1940 saw Ron’s admittance to the famed Explorers Club where he stood among the foremost adventurers of his day. Consequently, all subsequent expeditions were carried out under the coveted Explorers Club flag—most immediately a 1940 voyage to Alaska wherein he not only conducted landmark studies of Pacific Coast Indian tribes, but also pioneered a prototypic navigation system employed along all sea and air lanes into the latter decades of the twentieth century.

With the advent of the Second World War, Ron entered the United States Navy as a lieutenant. He initially served as a senior American intelligence officer in Australia. Upon his return to the United States (as the first American casualty of South Pacific combat) he went on to serve with distinction in both the North Pacific and Atlantic—commanding antisubmarine corvettes and training crews for amphibious landings. Although highly decorated for duties under fire, he was deeply saddened by the resultant carnage and inhumanity. Thus, he resolved to redouble his efforts to improve the human condition. Accordingly, he continued his research even through the darkest days of 1943 and 1944.

Left partially blind and lame from injuries sustained in combat, Lieutenant L. Ron Hubbard was diagnosed as permanently disabled by 1945 and hospitalized in Oakland, California. By this point, however, he had evolved the first practical procedures for alleviating trauma. He tested those procedures on former prisoners of war who, notwithstanding intensive medical treatment, had failed to regain their health. With the employment of early Dianetics techniques to remove “mental blocks” inhibiting response to medicine, all those Ron treated swiftly and remarkably recovered under standard medical care. Utilizing the same procedures, he likewise regained his own health—much to the bafflement of medical examiners.

With the restoration of peace, Ron set out to further test the workability of Dianetics among hundreds of individuals from all walks of life. After continued refinement in that “real-world laboratory,” he prepared a paper detailing both underlying theory and techniques. That paper was Dianetics: The Original Thesis. Copies of the manuscript were initially distributed to medical and scientific circles. In no time at all, however, those copies were eagerly recopied and passed on to others, until Ron’s Original Thesis was literally circulating around the world.
