Today, Mr Browning delivered the second Famous Brit of the Week assembly. This was an extra one to mark World Book Day, which is officially today but we are celebrating it properly tomorrow.
JK Rowling is the worlds first billionaire author, having sold over 400 million of her famous Harry Potter books.
She was working as a researcher and bilingual secretary for Amnesty International when she conceived the idea for the Harry Potter series while on a delayed train from Manchester to London in 1990. She has also written four books for adult readers:.
Rowling has lived a "rags to riches" life story, in which she progressed from living on state benefits to being the world's first billionaire author, although she has given away much of her earnings to charity. She is no longer a billionaire, she is still one of the wealthiest people in the world.
