Before the invention of the graphing calculator, scientists needed a clear, fast, and simple solution to understand and solve scale problems. The invention of the Gerber Variable Scale was that solution.
Heinz Joseph Gerber (1924-1996) invented the device while studying aeronautical engineering at the Rensselaer Polytechnic Institute in 1945, a few years after he had escaped from Nazi-controlled Austria with his mother. The first version of the variable scale was made with an elastic band removed from a pajamas. Gerber created a rubber scale and ruler that could expand, contract, and bend corners. It allowed direct numerical reading of curves, charts, and graphical representations.
Due to its ease of use and quick solutions, the Gerber Variable Scale was a great success and, in the 1950s, it was considered a tool universally used by engineers and architects around the world. Although calculators and computers have replaced it, the Gerber scale was an important part of the scientific advances of the 20th century.
The sixth coin in the American Innovation collection, which is being issued by the United States Mint, features this curious invention, the Gerber Variable Scale, which I personally was unaware of and for which there is very little information on Internet in Spanish. Thanks to the issuance of this currency, scheduled for the end of the month, I have discovered something else that I did not know existed.
The coins in this series honor innovation and innovators from each of the States and Territories of the United States, this time belonging to the State of Connecticut.

The design of the coin represents the Gerber Variable Scale being used to increase a geometric shape similar to the State of Connecticut by 200 percent. The inscriptions are "UNITED STATES Of AMERICA", "GERBER VARIABLE SCALE" and "CONNECTICUT".
Designer: Renata Gordon
Sculptor-Engraver: Richard Masters

The obverse features the same design common to the entire series, featuring the image of the Statue of Liberty in profile and the inscriptions "$ 1" and "IN GOD WE TRUST" (IN GOD WE TRUST).
The coins in this series show the year of issue or issue, the mint mark and the text “E PLURIBUS UNUM” (out of many, one) on the side of the coin.

Series of American Innovation dollars coins
The American Innovation coin series started in 2018 and will end in 2032, it is intended to honor innovation and innovators by issuing $ 1 coins for each of the 50 states, the District of Columbia and the five territories of the United States: Puerto Rico, Guam, American Samoa, the United States Virgin Islands and the Northern Mariana Islands.
Coins are available at face value in the United States. The order of issuance is the same as the States ratified the Constitution of the United States or were admitted to the Union. Once a coin is issued for each state, the coins for the District of Columbia and the territories will be released.
To finish I leave you a video that I have found on the Gerber Variable Scale. The explanations for its use are in English, but it is quite interesting.
