Hindenburg was a professor of philosophy and then physics at Leipzig. He is however best known for his mathematical work. In the book he lays out the design and theory behind a mechanical device independent of the work done by Felkel named the Erasthosthenes Sieve. Prior to Hindenburg it was the name given to a means of calculating all the prime numbers to a selected limit. It was Hindenburg who mechanized this method of accomplishing the calculations. In the book he establishes rules to both optimize and organize the device for calculating the primes. There are three folding plates of the device. The book also contains results in linear Diophantine analysis decimal periods combinations and gave combinatorial significance to the digits of numbers written in decimal notation. He later went on to publish work in combinatorials and could rightfully claim to be the founder of this approach in Germany.
