‘Who is Saruman?’ asked Pippin. 'Do you know anything about his history?' 

'Saruman is a Wizard,’ answered Treebeard. 'More than that I cannot say. I do not know the history of Wizards. They appeared first after the Great Ships came over the Sea; but if they came with the Ships I never can tell. Saruman was reckoned great among them, I believe. He gave up wandering about and minding the affairs of Men and Elves, some time ago–you would call it a very long time ago: and he settled down at Angrenost, or Isengard as the Men of Rohan call it. He was very quiet to begin with, but his fame began to grow. He was chosen to be head of the White Council, they say; but that did not turn out too well. I wonder now if even then Saruman was not turning to evil ways. But at any rate he used to give no trouble to his neighbours. I used to talk to him. There was a time when he was always walking about my woods. He was polite in those days, always asking my leave (at least when he met me); and always eager to listen. I told him many things that he would never have found out by himself; but he never repaid me in like kind. I cannot remember that he ever told me anything. And he got more and more like that; his face, as I remember it–I have not seen it for many a day–became like windows in a stone wall: windows with shutters inside.’

And in that year the White Council met for the last time, and Curunír withdrew to Isengard, and took counsel with none save himself. ~ The Silmarillion, Of the Rings of Power (Art: “Saruman the White”)

[White Council cont.] To this Curunír now assented, desiring that Sauron should be thrust from Dol Guldur, which was nigh to the River, and should have leisure to search there no longer. ~ The Silmarillion, Of the Rings of Power (Art: “Saruman vs. Gandalf” by DiscoveringArtWorld on DeviantArt) #Tolkien 

But [Curunír] spoke of none of this to the Council, hoping still that he might be the first to hear news of the Ring. ~ The Silmarillion, Of the Rings of Power (Art: “Of Gandalf and Saruman” by Mieronna on DeviantArt)

Then [Curunír] perceived that Sauron also had learned of the manner of Isildur’s end, and he grew afraid and withdrew to Isengard and fortified it; and ever he probed deeper into the lore of the Rings of Power and the art of their forging. ~ The Silmarillion, Of the Rings of Power

[Curunír]set a watch upon the Gladden Fields; but soon he discovered that the servants of Dol Guldur were searching all the ways of the River in that region. ~ The Silmarillion, Of the Rings of Power
