“Through faith we understand

That the worlds were formed

By the word of God,

So that things which are seen

Were not made of things which do appear.”

It is the wish of the members of the Hawaiian Volcano Research Association to share with others the experiences they have enjoyed in their association with a truly great man.

On October 5, 1911, through the efforts of Thomas Augustus Jaggar, Jr., the Hawaiian Volcano Research Association was organized to assist in the support of the newly created Hawaiian Volcano Observatory at Kilauea, Hawaii. Accepting Dr. Jaggar’s sincere belief that a systematic and continuous study of volcanoes would result in the protection of life and property, the motto the Hawaiian Volcano Research Association adopted was “Ne plus haustae aut obrutae urbes.”

Dr. Jaggar arrived in Hawaii to take up his work at the Observatory on January 17, 1912—exactly forty-one years before the day of his death on January 17, 1953.

Dr. Jaggar spent the last years of his life writing the history of his sixty years of intensive, rugged, and hazardous scientific achievements. During many of these years, and up to the completion of his life’s history, it has been well stated that one of his most valuable co-workers was his wife, Isabel, who shared with him the disappointments, the joys of discovery, and much of the physical work. It is the privilege of the officers, directors and members of the Hawaiian Volcano Research Association to present in book form this story of Dr. Jaggar’s life.
