<p>[QUOTE=&quot;kaparthy, post: 4900131, member: 57463&quot;]<i>The Imitation Game</i> (released December 25, 2014) was a movie about Alan Turing and the cryptanalysts at Bletchley Park. <b>Keira Knightley</b> played the role of <b>Joan Clarke. Joan Elisabeth Lowther Murray (nee Clarke)</b> was a brilliant mathematician, and an accomplished code-breaker. Clarke was also a numismatist. </p><p><br /></p><p>The British Numismatic Society granted her a Sanford Saltus Gold Medal in 1986. By then she was married; and to the BNS, she was <b>Joan E. L. Murray</b>. You can find a brief biography in Wikipedia, of course, but as Joan Clarke. </p><p><br /></p><p>Lord Stewartby (Bernard Harold Ian Halley Stewart), one of her collaborators in the coinage of Scotland, wrote the obituary for the <i>British Numismatic Journal </i>Vol. 67 No. 13, pg 162-167. Online here: <a href="http://www.britnumsoc.org/publications/Digital%20BNJ/pdfs/1997_BNJ_67_13.pdf" target="_blank" class="externalLink ProxyLink" data-proxy-href="http://www.britnumsoc.org/publications/Digital%20BNJ/pdfs/1997_BNJ_67_13.pdf" rel="nofollow">www.britnumsoc.org/publications/Digital%20BNJ/pdfs/1997_BNJ_67_13.pdf</a>)) That essay provided a bibliography, including papers she read at society meetings, but did not publish. </p><p><br /></p><p>Her husband, Lieutenant-Colonel John Kenneth Ronald (Jock) Murray, who also worked at the Government Communications Headquarters, introduced her to the problems attendant in <b>sequencing the gold unicorns and heavy groats of the kings James III and James IV of Scotland.</b> Joan E. L. Murray stands out among Saltus awardees for having done all of her work in the area of Scottish numismatics.[/QUOTE]</p><p><br /></p>
