Recent Reads: From Sail to Steam: Recollections of Naval Life by Alfred Thayer Mahan

 

Alfred Thayer Mahan shown late in his career (Naval History and Heritage Command)

By Dr. Ira Hanna
HRNM Docent

If any group of naval officers from any nation were asked what the name Mahan would bring to their minds, “Sea Power Wins Wars” would be their first choice. But Mahan’s life tells a lot more. From his first ship, the Congress, he learned what it felt like to be under “full sail.” Built in 1840, it represented the culmination of the era of sail. And from his last ship, the USS Wachusett, he became fully knowledgeable about being under “full steam.” This book is his story of how the U. S. Navy went from sail to steam power.

Mahan was born September 27, 1840, at West Point, New York, where his father was a professor at the Military Academy. Even so, he visited Norfolk often and became interested in the Navy and its ships. He always thought of himself as a Virginian. Although Mahan remained true to the Union during the “War of Secession,” he forever was influenced by the Chesapeake Bay. His father told him, “your mother is northern and very few can approach her, but still none compare for me the southern woman.” His father met Lafayette when he toured America in 1825-26 and spent time in France visiting him. His mother had a strong strain of French blood. Alfred said of himself that he was one half Irish, one quarter English, and “a good deal more than a trace of French.”

As a young boy, Mahan was fascinated by books written by the “old salts.” So it was not unusual that he chose to go to the Naval Academy rather than the Military Academy which his father preferred. In 1870, Mahan obtained command rank but was concerned with the “apathy” of the American people toward the navy. He called it a time of naval stagnation. That was when he began to read every book that told how sea power influenced the success of a nation, commercially as well as militarily.


By 1884, he had published a number of articles in popular magazines and become a regular lecturer at the Naval War College. He collected those articles and lectures into a book and in 1889 published The Influence of Sea Power upon History, 1660 – 1783. He continued to publish books that changed the way Americans, especially Congress and the President, felt about the need to build “a navy second to none.” Some of them were: The Influence of Sea Power upon the French Revolution and Empire, 1793 -1812 (published in 1892); The Life of Nelson (1897); The Interest of America in Sea Power, Present, and Future (1897); and The Major Operations of the Navies in the War of American Independence (1914). During his lifetime, Mahan authored over 40 books and before his death in 1914, predicted the defeat of the Central Powers and German Navy in World War I.

Although written in Victorian Era English with its hidden meanings, some revealing tales, and insights into the navy’s leadership, there is no doubt that Alfred T. Mahan influenced that leadership. The present navy reflects his belief that technological advances will influence what kind of ships will be built now and in the future in order for America to maintain its place as a world leader.

At HRNM: Scanning the Past, Printing the Future


By Joseph Miechle
Hampton Roads Naval Museum Educator

Recently at the Hampton Roads Naval Museum (HRNM) we had the opportunity to work with some local institutions in an exciting new capacity. We traveled to The National Museum of the Civil War Soldier at the Pamplin Historical Park in Petersburg, Virginia in order to 3D scan some rare Civil War artifacts.

We initially became aware of 3D scanning being used in historic institutions several years ago and have been trying to stay up with the technology as it evolves and incorporate it into our education programming. Scanning and printing of museum artifacts in 3D is a relatively new option but one that will certainly see more use as the technology becomes more viable and affordable. Here at HRNM we have purchased an affordable 3D scanner and our exhibits specialist had previously purchased his own 3D printer, which we utilize for printing our scanned objects. There are online companies that will print your scanned files for you and the Norfolk Public Library near our museum now has 3D printing capabilities.

Our 3D scanned images from Pamplin will be used to create faithful reproductions of artifacts that would normally not be permitted outside of the museum. This allows the public to hold and manipulate historic items they may not otherwise have the chance to do so. 3d printed objects are much more exciting for a learner than would be a traditional photograph. The use of 3D printed objects has other potential institutional uses as well.

The 3D printed objects can be used to facilitate visitation by visitors to museums that are sight impaired. Visually impaired visitors may be discouraged from visiting an institution that houses their entire collection behind acrylic cases, but the availability of 3D printed materials for them to experience could surely enhance their visit as well as the enjoyment they take away with them. We have even attempted to scan a traditional painting and to reprint it in 3D. Much of the detail was lost during the printing process but the implications are there and as the technology evolves we hope to gain greater results.

At the HRNM we have partnered with another local institution, The Hermitage Museum and Gardens, and have several 3D printed artifacts from our collection (several not normally removed from storage) that are on display as part of their “3D Printing the Smithsonian” exhibit. We also have included some of our 3D-printed objects in the HRNM’s Civil War Traveling Sea Chest, which contains resources for teachers to use in their classes while teaching on the subject of the American Civil War.
The 3D-printed duplicate of a Bashley Britten shell from CSS Florida (center left) is among several 3D-printed artifacts from the Hampton Roads Naval Museum that are currently on display at The Hermitage Museum and Gardens in Norfolk. With it are (from right) facsimiles of a temple bell removed from a pagoda on Tinian Island after it was captured by American forces in 1944, and (just under the bell) a pipe bowl recovered from the wreck of the sloop-of-war USS Cumberland. To the shell's right is a reproduction of a painting of the Battle of the Capes. (Photograph by Max Lonzanida)
It is certainly exciting to see these items up close and the experience of holding an item that bore witness to great historic events may be limited to few people, but 3D printing may be closing that gap and changing how museums share their collections with the public.
