This panel included those already experienced from Aktion T4, such as professors Werner Heyde and Hermann Paul Nitsche and doctors Friedrich Mennecke, Curt Schmalenbach, Horst Schumann, Otto Hebold, Rudolf Lonauer, Robert Müller, Theodor Steinmeyer, Gerhard Wischer, Viktor Ratka and Hans Bodo Gorgaß. To speed up the process, camp commandants made a preliminary selection list, as they had done in the T4 operation. This left just a few questions to be answered, such as personal information, date of admission to the camp, diagnosis of incurable disease, war injuries, criminal referral based on the criminal code of the Third Reich and any previous offenses.
