A Pauling biography

Sir-The review by R.J.P. Williams of Serafini's Pauling biography (Nature 342, 135; 1989) mostly displays William's musings as to what makes Pauling tick. While Williams is, of course, entitled to his opinions, our image of Linus Pauling is far more positive and we are especially incensed by the biographer's view of Paulings motivations, such as a need for tension and quarrels.
