  1. Integrate

    Build a personal workstation.

  2. Display

    Show interactive graphical information.

  3. Network

    Connect people and shared resources.

Personal workstations made graphical interfaces and networked applications tangible engineering possibilities.

The Alto was a research system, and its influence should be distinguished from later mass-market personal computers.

01 · The idea

In everyday language

Charles Thacker led the hardware design of the Xerox Alto and contributed to networking, multiprocessor workstations and other systems. The Alto combined a display, pointing device and computing resources at an individual’s desk. Its value came from bringing these capabilities into a working platform for new software and interaction.

Why it matters

Personal workstations made graphical interfaces and networked applications tangible engineering possibilities.

02 · The people

Who brought the idea to life?

Illustrated portrait of Charles Thacker

Charles Thacker

Charles Thacker designed influential computer hardware, most famously as a principal designer of the Xerox Alto personal computer. The Alto combined a graphical display, pointing device, local networking, and software into a new style of interactive computing. His later work at Digital and Microsoft continued to connect systems architecture with practical engineering. The award recognized both his pioneering personal-computing design and subsequent contributions to computer systems.
