+        <p>I am Frédéric Hecht, professor at Sorbonne University in Paris and I created FreeFEM with Olivier Pironneau.
+          I released FreeFEM in 1992, a new implementation of MacFEM completely re-written in C++.
           Twenty-seven years later, we were very proud to announce the release of <b>FreeFEM version 4</b>.</p>
         <p>With such a long history, a major code clean-up is now required to make FreeFEM's code easier to understand, maintain and modify.
           <b>Your donations are necessary to finance this heavy refactoring</b>. On behalf of the dev team, I thank you in advance for your support.</p>
