How does the author describe James Madison in the biography, The Great Little Madison?

Fritz says, "James Madison was a small, pale, sickly boy with a weak voice." Although five feet six inches tall, his slight build and weak voice made him seem smaller; in fact, "people were forever remarking on his littleness." Furthermore, "All his life he suffered from fever, bilious attacks (liver upsets), and from occasional seizures in which for a few moments he would stiffen and lose control of his mind." These seizures were probably caused by epilepsy.
