Quick Facts

Rising from Bavarian Roots to Global Tech Impact

Andy Bechtolsheim’s journey begins on a remote farm in Bavaria where he grew up with few neighbours and no television — a setting that, he observes, fostered his early fascination with electronics.  As the second of four children, and living near Lake Ammersee in Germany, he started building motors and circuits at a very young age.

After winning a national youth physics contest (Jugend forscht) in 1974, he studied electrical engineering at the Technical University of Munich, then went on to a master’s at Carnegie Mellon University and later to a PhD programme at Stanford University.

In 1982 he co-founded Sun Microsystems with Bill Joy, Scott McNealy and Vinod Khosla, and became its chief hardware designer.  His early design of a workstation called the “SUN” (Stanford University Network) became the foundation for the company’s early offerings.

Defining moments in Andy Bechtolsheim’s journey include:

• Designing a microprocessor-based industrial controller at age 16, using the Intel 8008, and earning royalties.

• Co-founding Sun Microsystems in 1982 and contributing to the development of the SPARC workstation line.

• Early angel investing in Google: writing a $100,000 cheque pre-incorporation. 

• Founding or co-founding high-speed networking ventures including Granite Systems (sold to Cisco) and Arista Networks.
