The Supervisory Board of Rational AG has unanimously elected Walter Kurtz as its new Chairman. The election was necessary since the company founder and former Supervisory Board Chairman Siegfried Meister died on 28 July 2017 at the age of 78. Walter Kurtz had worked for more than 48 years with Siegfried Meister as his closest confidant. He has been a majority shareholder and member of the Supervisory Board - most recently as deputy chairman - since the foundation of Rational AG in 1998. Dr Hans Maerz, who has been on the Supervisory Board of Rational AG since 2011 and was previously second deputy, was unanimously elected as the new deputy chairman. Dr. Maerz previously spent many years acting as an auditor for Rational AG. The Supervisory Board also announced that the contract with Dr. Peter Stadelmann as CEO has been extended for a further five years. He joined the Executive Board at the end of 2012 and took over as Chief Executive Officer a year later.
