  <dc:title>Letter from Richard Willstatter to Michael Heidelberger</dc:title>
  <dc:subject>Polysaccharides</dc:subject>
  <dc:subject>Streptococcus pneumoniae</dc:subject>
  <dc:description>In this letter Heidelberger&apos;s former mentor, the organic chemist and Nobel Laureate Richard Willstatter, acknowledged initial doubts regarding Heidelberger&apos;s and Oswald Avery&apos;s findings in 1923 and 1924 that powerful antigens of type-specific pneumococcus bacteria are polysaccharides.  Willstatter had instead thought that &quot;adsorbed traces of a highly reactive unknown substance&quot; might determine the bacteria&apos;s pathogenicity.  Since then, however, he admitted that it had become clearer that Heidelberger&apos;s work &quot;created a great new advance in the field and that you have prevailed completely.&quot;</dc:description>
