Ordinarily, modern advances in the theory of complex variables for problems that are of a level comprehensible to readers of this book are extremely rare. A remarkable exception occurred in the year 1984--within the lifetime of many readers--for it was then that a relatively obscure mathematician at Purdue University, Louis de Branges, published his solution of a famous unsolved problem in functions of a complex variable: the Bieberbach conjecture...He was 54 years old at the time of his breakthrough, an age at which most mathematicians are beyond their best work...

So maybe I will be able to write that proof!
