Andreas von Bechtolsheim & family

Andreas "Andy" von Bechtolsheim is cofounder, chairman and chief development officer of network switching company Arista Networks.

Much of his fortune stems from an early $100,000 investment in Google.

He has earmarked his nearly 17% stake in Arista for his heirs.

In 1982, he cofounded tech hardware firm Sun Microsystems with Bill Joy, Scott McNealy and Vinod Khosla. Oracle bought Sun in 2010 for $7.4 billion.

Born in Germany, Bechtolsheim studied computer engineering at Carnegie Mellon University and received his PhD from Stanford University.
