There were four mint strikes of the Connecticut American Innovation Dollar in 2020. A Gerber Variable Scale was featured on each coin.
Science needed a clear, quick, and simple method to understand and solve scale problems before the invention of the graphing calculator or even computers in general. Fortunately, the Gerber Variable Scale was created to fill that need.
Joseph Gerber was a junior engineering student at Rensselaer Polytechnic Institute when he escaped Nazi persecution in Austria in 1942. Gerber developed the first Gerber Variable Scale by using elastic bands from his pajamas to cope with his increasingly time-consuming and challenging Engineering tasks.
Scales such as this work much like standard rulers. It is possible to stretch the spring coils of the Gerber Variable Scale up to ten inches in length. A logarithmic scale that uses short coil lengths to estimate mathematical distances and solutions can calculate far sizes or complicated measurements.
American Innovation Dollar Characteristics
As shown on the reverse, a drawing of Connecticut is enlarged by 200 percent using the Gerber Variable Scale. Several inscriptions appear, including “United States of America,” “Gerber Variable Scale,” and “Connecticut.” Richard Masters designed the reverse, which Renata Gordon sculpted.
