Chronological bio on edward lear

Edward's upbringing was entrusted to his sister Ann, twenty-one years his senior, and Mrs Lear had nothing more to do with it. Young Edward certainly resented his mother's rejection, but found all the love he needed in Ann.
He was first attacked by what he called 'the Demon', epilepsy, when he was five or six, and a few years later 'the Morbids', sudden changes of mood with bouts of acute depression, began.
His early education was completely left to Ann and Sarah, another sister: beside the typical tuition books of the age they read to him classical tales and modern poetry (the Romantic poets), and taught him to draw, especially natural subjects.
