An instrument maker in Augsburg, Brander was known<br />
as one <strong>of</strong> the finest workmen <strong>of</strong> his day, and many <strong>of</strong> his<br />
instruments are in museums today. He is known to have<br />
had almost a hundred different instruments <strong>of</strong> his own<br />
design for sale and is also known to have written several<br />
books on these instruments and their use (see Brander,<br />
Beschreibung und Gebrauch …, 1780).<br />
This work on binary numbers was a very early explanation<br />
<strong>of</strong> the system. In the introduction he credits Leibniz with<br />
earlier work. The slim volume starts with an explanation<br />
<strong>of</strong> the system; proceeds to describe addition, subtraction,<br />
multiplication, division and the extraction <strong>of</strong> roots;<br />
then concludes with a table <strong>of</strong> the binary equivalents <strong>of</strong><br />
numbers from 0 to 500,000.<br />
