In 1975 he was in charge of the simulation and reconstruction software for [[NA44]] where [[GEANT1]] and [[GEANT2]] were created. In 1981, he joined [[OPAL]] at LEP, creating the [[GEANT3]] detector simulation system, also pioneering the introduction of the first workstations like Apollos in Europe. In 1984 he coordinated the development of the [[PAW]] (Physics Analysis Workstation) data analysis system and until 1994 he was in charge of the Application Software group in the computing division. In 1995 he created the [[ROOT]] system while working for the [[NA49]] heavy ion experiment at the SPS. Brun has been leading the ROOT project from 1995-2011. He is still active and following his retirement he has the chance to work on his own project on Physics models.&amp;lt;ref&amp;gt;Interview with René Brun by Panos Charitos, Newletter of the EP Department, 24th Mar 2013, https://ep-news.web.cern.ch/content/interview-rene-brun.&amp;lt;/ref&amp;gt;&lt;/div&gt;&lt;/td&gt;&lt;td class=&quot;diff-marker&quot;&gt;&lt;/td&gt;&lt;td style=&quot;background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;René Brun&amp;#039;&amp;#039;&amp;#039; joined CERN in 1973.
