Marvin W. Barrash

The Mysterious Disappearance of the U. S. S. Cyclops

Marvin W. Barrash was introduced to the U.S.S. Cyclops at an early age. His father told him that his great uncle was lost with the Collier Cyclops during the First World War. That bit of family history made an impression on him. Years later, he authored three books concerning the U.S.S. Cyclops. Following his initial thirteen years of extensive research of surviving Cyclops documentation, his book, U.S.S. CYCLOPS, the comprehensive history of the ship, was completed. His next volume was, Murder on the Abarenda, a pre-history of the Cyclops saga that delved into the prior sea service of the ship’s only commanding officer. His third book, U.S.S. CYCLOPS, Volume Two, focused on the men who perished with the ship and provided information that was not previously available. Mr. Barrash’s decades of research of the Cyclops’ history never ceased. He continues with the hope that the ship will be located and studied; not salvaged. The cause of the ship’s demise and the terrible loss of life with her must be ascertained. Barrash retired after more than four decades of service with the U.S. Department of Defense. His military service was in the Maryland Army National Guard. He resides in Maryland.
