Julius August Christoph Zech
Julius August Christoph Zech was a German astronomer and mathematician.
In 1849, Zech published a table of logarithms; as a result, Zech logarithms for finite fields are named after him.
In 1863, Zech attended the founding meeting of the Astronomische Gesellschaft and became its Vorstand. Friedrich Wilhelm Argelander assumed this role upon Zech's death.
