    <description>
&lt;P&gt;A very carefully brought up young man.  His father, Leo Wiener, was a
professor of Slavic languages and literature at Harvard, who had pronounced and
peculiar views on education, and put them into effect on young Norbert.
(Wiener &lt;em&gt;p&amp;egrave;re&lt;/em&gt; also had a crackpot theory about the African
discovery of American c. 1000 A.D., but that's another story.)  The net effect
of these practices was that Norbert got his Bachelor's at the age of 14, and
his Ph.D. (from &amp;mdash; where else? &amp;mdash; Harvard, in mathematical
philosophy) at the age of 18, at which point he headed to Europe to study at
G&amp;ouml;ttingen and Cambridge
(under &lt;a href=&quot;bertrand-russell.html&quot;&gt;Russell&lt;/a&gt;).  After various
peregrinations he settled at the math department of MIT, where he did lots of
good work on algebra and measures, at last finding his true home
in &lt;a href=&quot;stochastic-processes.html&quot;&gt;stochastic processes&lt;/a&gt; and their
applications to &lt;a href=&quot;time-series.html&quot;&gt;time series&lt;/a&gt; and the foundations
of &lt;a href=&quot;stat-mech.html&quot;&gt;statistical mechanics&lt;/a&gt;.

&lt;P&gt;In his younger years, he was (by his own account) a barely-ambulatory bundle
of neuroses, and insufferable; he improved with age, to the point of being
merely vain and arrogant.  In all fairness, he had a lot to be arrogant about:
in addition to his mathematics, he was one of the founders
of &lt;a href=&quot;cybernetics.html&quot;&gt;cybernetics&lt;/a&gt;, and the man who coined the word
(from the Greek &lt;em&gt;kubernetes,&lt;/em&gt; steersman, whence also &quot;governor&quot;).  He
defined it as &quot;the science of control and communication in the animal and the
machine,&quot; and thought it was basically
about &lt;a href=&quot;information-theory.html&quot;&gt;information theory&lt;/a&gt; and feedback,
and how animals and machines manage to &lt;em&gt;do&lt;/em&gt; things; and he warned, as
explicitly as possible, against using it for handwaving fluff in social science
or philosophy.  (These warnings were, naturally, ignored; but that is also
another story.)  He realized, of course, that understanding that would lead to
better automatic machinery, with profound but unpredictable consequences, and
he wrote a lot to try and make people think about them.  (They didn't, but
that's yet another story.)  He was less than entirely successful as
a &lt;A href=&quot;prophecy.html&quot;&gt;prophet&lt;/a&gt; &amp;mdash; for instance, automation has not
&lt;em&gt;yet&lt;/em&gt; resulted in mass unemployment &amp;mdash; but nobody is or was, and
his heart at least was in the right place.
