More About Hal Jespersen

Hal Jespersen is a retired computer industry executive who has a strong interest in studying the Civil War. Hal was a U.S. Army Signal Corps officer in the 1970s and then held a variety of computer software jobs in Silicon Valley until his retirement in 2010. 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 published over 160 Civil War battle maps, which are starting to appear in a number of online sites and some recently published books. Hal focuses his interests primarily east of the Mississippi, and although he loves the Army of the Potomac, feels that the war was substantially won in the Western Theater.

Hal's website,, contains links to his maps, 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: [San Francisco] Peninsula, South Bay (San Jose), and Old Baldy (Philadelphia).
