My Take

John Hennessy sits in a category of his own for me. A Turing Award laureate who also ran Stanford for sixteen years, he managed to reach the summit as both scholar and leader, a genuine rarity. As a co-founder of MIPS and Atheros and now chairman of Alphabet, he straddles research, entrepreneurship and institutional power with unusual grace. The computer architecture ideas he helped shape quietly underpin the devices we touch every day. There is nothing showy about him, and that is exactly the point. When people speak of a giant of the field with real humility, Hennessy is the figure I picture.
