Eric Klieg Eric Klieg was a member of the Brotherhood of Logicians . Biography . Klieg , his colleague Kaftan and her servant Toberman accompanied Professor Parry ' s expedition to Telos to search for the tomb of the long - dormant Cybermen . He and Kaftan had funded the expedition in the hope they would be able to contact with the Cybermen and convince them to work with the Brotherhood to obtain power . The party eventually found the tomb after blasting away the side of rock face . Once in the tomb , Klieg set to work deciphering the logic patterns that granted access to the tombs themselves . After several failures , he managed it and most of the party went down , with Kaftan , Victoria Waterfield , Captain Hopper and the spacecraft crew staying behind . When Kaftan shut the hatch behind them , the Second Doctor realised from Klieg ' s lack of distress that he was planning something , but allowed him to carry it out . Klieg claimed he could re - open the hatch using the controls next to the dormant Cybermen but , instead , he used them to wake the sleepers . John Viner tried to return them to their sleep , for which Klieg shot and killed him . The Cyber - Controller listened to Klieg ' s proposition of mutual assistance before grabbing his arm and throwing him to the ground , declaring ownership over him and the others . Captain Hopper came into the tombs and used smoke bomb s to create a distraction and allow the group to escape . Klieg was left behind and the hatch was shut in front of him . He knocked on it and , the lightness of this , was recognised as human by the Doctor , so the party re - opened the hatch . Unwilling to have the schemers near them , Parry and the other expedition crew removed Klieg and Kaftan to the weapons testing room . However , there they were able to obtain a cyber - gun . Klieg believed it would give him bargaining power over the Cybermen , but first wanted to kill the Doctor . He fired upon him , but Jim Callum stepped in the way and was hit in the shoulder . Klieg used the gun to force the others to open the hatch . He shouted down that he demanded negotiations with the Cyber - controller , who emerged with the partially converted Toberman . Kaftan asked Klieg to obtain release for her servant , which he did as part of the negotiations , unaware that the controller desired this end , having control over Toberman ' s mind . After the controller was revitalised , he had Toberman strike Klieg , knocking him unconscious . When he awoke , he found Toberman , the Doctor and Jamie McCrimmon had re - entered the tomb , with the Cyber - Controller inactive on the floor nearby . Klieg woke the Cybermen again , who had returned to dormancy to conserve energy , still set on forming an alliance with them . While they awoke , the Doctor praised his genius and flattered him as to the greatness of his leadership in the future . Klieg imagined himself as " master of the world " . The Doctor replied that he " just wanted to make sure " he was in fact mad , and counted this delusion as proof . Klieg mocked them , telling him he would not kill them but leave them to the Cybermen , who would have use for " parts of you " . As he talked , a Cyberman grabbed him from behind and beat him to death . ( TV : " The Tomb of the Cybermen " )
