As long as there's no word boundry touched, it won't remove the "I" in the author name; however, it will remove the personal pronoun "I". I'd do something like this:
#!/usr/bin/perl -l
use strict;
use warnings;
my(@data) = q(
1. Iilliam H. Schneider, IV
2. William Vassilakis, II
3. Alessandro Calvi, I
);
foreach my $data (@data) {
$data =~ s/\b[IVXLCDM]+\b//g;
chomp $data;
print "$data\n";
}
I used "Iilliam" instead of "William" for demonstration purposes.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
