notes: label: Description
content: In the 1970s, James D. Lehman, a laboratory technician in the physics department at James Madison University, developed a seismograph that was simple enough for students and amateurs to make, and sensitive enough to detect earthquakes and underground nuclear tests. This item is a cover for that instrument.
