Since 1965, award-winning, internationally published features describing the vital but overlooked people, places, and significant events of the 20th Century.  Enter the same history-changing but intact locales from the past as they appeared then in rare photos and as they are now.

Every locale is personally visited, extensively researched, and fully documented with photos from the era contrasted with present-day images.  These include world exclusives in revealing the intact existence of Winston Churchill’s wartime Cabinet War Rooms, and in disclosing the equally intact existence of Bletchley Park, where the German Enigma cypher was broken by 12,000 British codebreakers.

The author, a Chicago-based educator and dynamic program presenter, is available for 60-90 minute image-based presentations about any of the original features appearing on this site.  Jerome O’Connor was named the U. S. Naval Institute’s 2001 “Author of the Year”.

Group tours are available for the Chicago locales described. Complete the contact form for information and availability.
