 A: Winfried Scharlau wrote a biography about Alexander Grothendieck, who had a deep influence on modern algebraic geometry. The title is "Wer ist Alexander Grothendieck? Anarchie, Mathematik, Spiritualität(, Einsamkeit)". As far as I know it was planned to appear in three volumes. The first one and the third one volume already appeared. The last word of the title was not present yet in the first volume. I guess Scharlau decided later to add a fourth volume. As far as I know, the first volume has to be ordered directly from the author, while the third one is available in bookstores. 
Unfortunately both appeared first in German. Though, the first volume has been translated to English by Melissa Schneps. Its title is "Alexander Grothendieck? Anarchy, Mathematics, Spirituality, Solitude".
They are not merely about Grothendieck's achievements in mathematics, but cover more aspects about his life, as the title indicates.
