RICHARD L. SCHMOYER
The Sunquest Sundial was invented by Richard L. Schmoyer in the 1950s.
Adjustable for latitude and longitude, the Sunquest's gnomon automatically corrects for the "equation of time" making it a rare sundial that actually tells clock time.
The Sunquest sundial is on public exhibit in botanical gardens, museums, observatories, and other locations in North America.
