What does/did a Postmaster do?
<p>Reading the list of officers of the <a href="http://history.house.gov/Congressional-Overview/Profiles/59th/" rel="nofollow">59th Congress</a>, I see someone whose job I can't figure out:</p>

<blockquote>
  <p><strong>Postmaster:</strong><br>
  J.C. McElroy</p>
</blockquote>

<p>What did the Postmaster do? Was it his job to oversee the nation's postal service? There doesn't seem to be a corresponding position today.</p>

<p>They ran the mail service for the <em>House of Representatives</em>, not for the country as a whole (that was, and still is, run by the Postmaster General). <a href="https://en.wikipedia.org/wiki/Postmaster_of_the_United_States_House_of_Representatives">The position was eliminated in 1993</a>, with duties reassigned to other personnel.</p>
