Herophilus, Erasistratus, Rhazes, and Avicenna are not in this book.
The first two were the founders of anatomy, physiology, and empirical medicine in antiquity, Rhazes the greatest physician of Islam, and Avicenna "the greatest scientist of all races, places, and times" according to George Sarton.
Beyond this, those biographies contained are sketchy, incomplete, and sometimes contain factual errors.
don't bother.
