Ernst Blaschke was a pr<strong>of</strong>essor at the Technischen<br />
Hochschule in Vienna.<br />
This volume is not directly concerned with calculating<br />
machinery until the last <strong>chapter</strong>, when the author<br />
describes some <strong>of</strong> the new punched card machinery. In<br />
particular, he briefly describes the Hollerith machines<br />
used for the U.S. census and also equipment developed<br />
specifically for the insurance industry by John K. Gore,<br />
an actuary at the Prudential Life Insurance Company.<br />
Gore’s little-known system is illustrated with his card<br />
punch and sorting machine.<br />
