**John Hamal Hubbard** (born October 6 or 7, 1945) is an American
mathematician and professor at
Cornell University and the
Université de Provence. He is known for the mathematical contributions he made with
Adrien Douady in the field of
complex dynamics, including a study of the
Mandelbrot set. One of their most important results is that the
Mandelbrot set is
connected.

Hubbard graduated with a
Doctorat d'État from
Université de Paris-Sud in 1973 under the direction of
Adrien Douady; his thesis was entitled *Sur Les Sections Analytiques de La Courbe Universelle de Teichmüller* and was published by the
American Mathematical Society.

Hubbard and his wife
Barbara Burke Hubbard wrote the book *Vector Calculus, Linear Algebra, and Differential Forms: A Unified Approach*.

He has also published three volumes of a book on Teichmüller theory and its applications to four revolutionary theorems of William Thurston.

Hubbard is married to
Barbara Burke Hubbard, a science writer. Together they have a son and three younger daughters.^{
