Meeting of January 10, 2019

Join us at 7:15 PM on Thursday, January 10, at Camden County College in the Connector Building, Room 101. This month’s topic is

Hal Jespersen on “Civil War Cartography”

Readers say that one of the most important features of a modern book about the Civil War is a good collection of understandable, accurate maps. Hal’s presentation, offered via Skype from California, will reveal some of the details behind the process for creating such maps. Hal Jespersen’s cartography business has produced over 2,900 maps for Wikipedia and numerous books, magazines, and battlefield displays. Hal will discuss the state of mapmaking during the war, review the work of some famous cartographers, and describe tools and processes he uses to create maps. Some of the technical concepts included were projection, elevation rendering, evaluating the accuracy of the Official Records Atlas, and plotting the courses of 19th century rivers, roads, and railroads.

Hal Jespersen is a retired computer industry executive—formerly of Sun Microsystems—who has a strong interest in studying the Civil War. Hal was a U.S. Army Signal Corps officer in the 1970s, including Viet Nam, and then held a variety of computer software jobs in Silicon Valley until his retirement in 2010. Although he studied some military history and visited some battlefields as an ROTC cadet, Hal’s overriding interest in the war was triggered recently by a specific event—reading Michael Shaara’s The Killer Angels in 2003. That led to a period of voracious reading about the Battle of Gettysburg and to the first of a number of trips to that hallowed ground.

In 2004, Hal began to make significant contributions to the Civil War articles on Wikipedia, and is the principal author of about 130 battle and campaign articles as well as an equal number of biographical articles about Civil War generals. In addition to the text of the articles, Hal has produced over 2,900 Civil War battle maps, which are appearing in a number of online sites and numerous books. Hal focuses his interests primarily east of the Mississippi, and although he loves the Army of the Potomac, believes that the war was substantially won in the Western Theater.

Hal’s mapping website, www.CWMaps.com, includes about 200 freely available maps of the war, as well as information about his custom cartography business. His personal website, www.posix.com/CW/, contains links to his important Wikipedia articles and a large number of travelogue articles, recording his visits to Civil War battlefields and seminars over the years. Hal is the webmaster for three Civil War Round Tables, including Old Baldy.
