Tamwile Elar (Forward the Foundation) is a senior mathematician working on the Seldon Project. The creater of 'the achaotic equations' that make it more possible to get around the problem of chaos and aid in developing psychohistory, Seldon thinks of him as a brilliant man, though is sometimes a bit begrudging or annoyed internally because he thinks of himself as no longer as good as he used to be, as he ages, and dislikes Elar's loud laugh and habit of calling Seldon 'the Maestro.' Elar designs an 'Electro-Clarifier' device to allow more information to be stored in 'Prime Radiants' that hold psychohistorical equations. However, whilst collaborating with the military junta that rules Trantor, he kills Dors Venabili with an intense Electro-Clarifier through its side effect of creating an electomagnetic field that damages the electromagnetic machinery of robots without harming humans. It seems Elar wants to become the head of the Psychohistory Project, and the junta wants Seldon out of the picture so he cannot decry their government as failing, but feels Dors would be difficult to get past. However, Elar does not appear to especially dislike Seldon, and perhaps is even glad that Seldon might drift away with Dor's death without having to be killed by the junta. Dors nevertheless manages to kill Elar and tell Seldon what has happened before dying.
