Saunders Mac Lane was not only a leader in the mathematics community but also an inspiration to working mathematicians, graduate students and also undergraduates. In teaching generations of undergraduate students he inspired and laid down a standard for future generations of teachers. He taught many that the beauty of mathematics can and should be communicated to all.
