PARC (Palo Alto Research Center; formerly Xerox PARC) is a research and development company in Palo Alto, California. Founded in 1969 by Jacob E. "Jack" Goldman, Xerox Corporation's chief scientist, the company was originally a division of Xerox, tasked with creating computer technology-related products and hardware systems.

Xerox PARC has been at the heart of numerous revolutionary computer developments as laser printing, Ethernet, the modern personal computer, graphical user interface (GUI) and desktop paradigm, object-oriented programming, ubiquitous computing, electronic paper, amorphous silicon (a-Si) applications, the computer mouse, and advancing very-large-scale integration (VLSI) for semiconductors. Jack's “Advanced Scientific & Systems Laboratory” aimed to develop future technologies; it was not intended to reproduce the already existing Xerox's research laboratory in Rochester, New York, which focused on refining and expanding the company's copier business. Instead, Xerox PARC was a site for pioneering work in advanced physics, materials science, and computer science applications.
Xerox formed Palo Alto Research Center Incorporated as a wholly owned subsidiary in 2002.
In 1969, Jack Goldman, Xerox's Chief Scientist, spoke to George Pake, a physicist specializing in nuclear magnetic resonance and provost of Washington University in St. Louis, about starting a second research center for the company.
On July 1, 1970, the Xerox Palo Alto Research Center opened. While the 3,000-mile buffer between it and Xerox headquarters in Rochester, New York afforded scientists at the new lab great freedom to undertake their work, the distance also served as an impediment in persuading management of the promise of some of their greatest achievements.
PARC's West Coast location proved to be advantageous in the mid-1970s, when the lab was able to hire many employees of the nearby SRI Augmentation Research Center (ARC) as that facility's funding began falling, from the Defense Advanced Research Projects Agency (DARPA), National Aeronautics and Space Administration (NASA) and U.S. Air Force (USAF). Being situated on Stanford Research Park land leased from Stanford University encouraged Stanford graduate students to be involved in PARC research projects and PARC scientists to collaborate with academic seminars and projects.
Much of PARC's early success in the computer field was under the leadership of its Computer Science Laboratory manager Bob Taylor, who guided the lab as associate manager from 1970 to 1977 and as manager from 1977 to 1983.
After three decades as a division of Xerox, PARC was transformed in 2002 into an independent, wholly owned subsidiary company dedicated to developing and maturing advances in science and business concepts. PARC's research areas encompass a range of disciplines in hardware, software, social sciences, and design. Areas include ubiquitous sensing, electrochemical energy systems, material deposition systems, polymeric and composite materials, semiconductor materials, printing for manufacturing, optical sensors, optical and mechanical microsystems, printed and hybrid electronics, large-area thin-film electronics, optoelectronic devices, user experience design, systems security, system prognosis and health management, modeling and simulation of cyber-physical systems, interactive machine learning, human-machine collaboration, geometric and spatial reasoning, data science, conversational agents, and computer vision and image synthesis.
Xerox PARC has been the inventor and incubator of many elements of modern computing in the contemporary office work place:
- Laser printers
- Computer-generated bitmap graphics
- The graphical user interface, featuring skeuomorphic windows and icons, operated with a mouse
- The WYSIWYG text editor
- Interpress, a resolution-independent graphical page-description language and the precursor to PostScript
- Ethernet as a local-area computer network
- Fully formed object-oriented programming (OOP) (with class-based inheritance, the most popular OOP model to this day) in the Smalltalk programming language and integrated development environment
- Prototype-based programming (the second most popular inheritance model in OOP ) in the Self programming language
- Model–view–controller software architecture
- AspectJ an aspect-oriented programming (AOP) extension for the Java programming language
Most of these developments were included in the Alto, which added the now familiar Stanford Research Institute (SRI) developed mouse, unifying into a single model most aspects of now-standard personal computer use. The integration of Ethernet prompted the development of the PARC Universal Packet architecture, much like today's Internet.
Xerox has been heavily criticized (particularly by business historians) for failing to properly commercialize and profitably exploit PARC's innovations. A favorite example is the graphical user interface (GUI), initially developed at PARC for the Alto and then commercialized as the Xerox Star by the Xerox Systems Development Department. Although very significant in terms of its influence on future system design, it is deemed a failure because it only sold approximately 25,000 units. A small group from PARC led by David Liddle and Charles Irby formed Metaphor Computer Systems. They extended the Star desktop concept into an animated graphic and communicating office-automation model and sold the company to IBM.
Bill Gates, the founder of Microsoft later stated that the Xerox graphical interface influenced both Microsoft and Apple, and Steve Jobs of Apple said that “Xerox could have owned the entire computer industry, could have been the IBM of the nineties, could have been the Microsoft of the nineties."
Among PARC's distinguished researchers were three Turing Award winners: Butler W. Lampson (1992), Alan Kay (2003), and Charles P. Thacker (2009). The Association for Computing Machinery (ACM) Software System Award recognized the Alto system in 1984, Smalltalk in 1987, InterLisp in 1992, and the remote procedure call in 1994. Lampson, Kay, Bob Taylor, and Charles P. Thacker received the National Academy of Engineering's prestigious Charles Stark Draper Prize in 2004 for their work on the Alto.
PARC's developments in information technology served for a long time as standards for much of the computing industry. Many advances were not equalled or surpassed for two decades, enormous timespans in the fast-paced high-tech world.
While there is some truth that Xerox management failed to see the potential of many of PARC's inventions, this was mostly a problem with its computing research, a relatively small part of PARC's operations. A number of GUI engineers left to join Apple Computer. Technologies pioneered by its materials scientists such as liquid-crystal display (LCD), optical disc innovations, and laser printing were actively and successfully introduced by Xerox to the business and consumer markets.
