George Langford, Sr. at his desk in the Field Museum.
25 Years Ago - April 1998
- The Gem, Mineral, and Fossil show for 1998 was huge success. The newsletter had a report.
- There were 48 display cases at the show! Where did they find the room?

50 Years Ago - April 1973
- The General Meeting topic was devoted to the various junior groups.... of which there were two - Downers Grove and Western Springs.
