Question: What are both Naval History and Blender?
Context: Blender was an American music magazine that billed itself as "the ultimate guide to music and more".  It was also known for sometimes steamy pictorials of celebrities.  It compiled lists of albums, artists, and songs, including both "best of" and "worst of" lists.  In each issue, there was a review of an artist's entire discography, with each album being analyzed in turn. Historical accounts for early U.S. naval history now occur across the spectrum of two and more centuries.  This Bibliography lends itself primarily to covering early U.S. naval history beginning around the American Revolution period on through the 18th and 19th centuries and includes sources which cover notable naval commanders, Presidents, important ships, major naval engagements and corresponding wars.  The bibliography also includes sources that are not committed to the subject of U.S. naval history per se but whose content covers this subject extensively. The Secretary of the Navy's Research Chair in Naval History was established in 1987 by the then Naval Historical Center, Department of the Navy (now known as the Naval History & Heritage Command).  This competitive appointment was designed to support, for up to three years, a scholar in researching and writing a major monograph on the history of the U.S. Navy since 1945. Admiral Sir Herbert William Richmond {'1': ", '2': ", '3': ", '4': "} (15 September 1871 – 15 December 1946) was a prominent Royal Navy officer, described as "perhaps the most brilliant naval officer of his generation."  He was also a top naval historian, known as the "British Mahan", the leader of the British Royal Navy's intellectual revolution that stressed continuing education especially in naval history as essential to the formation of naval strategy.  After serving as a "gadfly" to the British Admiralty, his constructive criticisms causing him to be "denied the role in the formation of policy and the reformations of naval education which his talents warranted", he served as the first Vere Harmsworth Professor of Imperial and Naval History at Cambridge University in 1934-1936, and Master of Downing College, Cambridge in 1934-1946. USS "Cyclops" (AC-4) was one of four "Proteus"-class colliers built for the United States Navy several years before World War I.  Named for the Cyclops, a primordial race of giants from Greek mythology, she was the second U.S. Naval vessel to bear the name.  The loss of the ship and 306 crew and passengers without a trace within the area known as the Bermuda Triangle some time after 4 March 1918 remains the single largest loss of life in U.S. Naval history not directly involving combat.  As it was wartime, there was speculation she was captured or sunk by a German raider or submarine, because she was carrying 10800 LT of manganese ore used to produce munitions, but German authorities at the time, and subsequently, denied any knowledge of the vessel.  The Naval History & Heritage Command has stated she "probably sank in an unexpected storm" But the ultimate cause of the ship's fate is unknown. The Naval Historical Foundation, a nonprofit organization founded in 1926, has a broad mission to preserve and promote the naval history of the United States by supporting official Sea Services programs and institutions, meeting the needs of the public for naval history, and collecting historical items.  The Foundation is located at the Washington Navy Yard, in Washington, D.C. Naval History is a bi-monthly magazine published by the United States Naval Institute since 1987.  The 72-page publication not only includes feature articles spanning the course of Naval History written by significant scholars of their subject, but also has standing features including: "Looking Back," "On Our Scope," "Naval History News," "Book Reviews," and "Museum Report." The Naval History Society was a historical organization that existed in New York City from 1912 to 1936.  The collection of documents, books, manuscripts, and memorabilia related to naval and military history was housed in Aeolian Hall on West 42nd Street 1912 to 1925 when it was relocated to the New-York Historical Society and ceased independent operations in 1936 becoming that societies "Naval History Society Collection". The Naval History and Heritage Command, formerly the Naval Historical Center, is an Echelon II command responsible for the preservation, analysis, and dissemination of U.S. naval history and heritage located at the historic Washington Navy Yard.  The NHHC is composed of 42 facilities in 13 geographic locations including the Navy Department Library, 10 museums and 1 heritage center, USS "Constitution" repair facility and detachment, and historic ship ex-USS "Nautilus". The Julian Corbett Prize in Modern Naval History was established in 1924 by Mr. H. E. Corbett in memory of his brother, the great naval historian Sir Julian Corbett (1854-1922).  First awarded in 1926, the prize has been offered annually by the University of London for a piece of original research in the field of naval history.
