An Wang (; February 7, 1920 – March 24, 1990) was a Chinese-American computer engineer and inventor, and cofounder of computer company Wang Laboratories, which was known primarily for its dedicated word processing machines. An Wang was an important contributor to the development of magnetic-core memory.
In 1955, when the core memory patent was issued, Wang sold it to IBM for and incorporated Wang Laboratories with Ge-Yao Chu, a schoolmate. The company grew slowly and in 1964 sales reached . Wang began making desktop electronic calculators with digital displays, including a centralised calculator with remote terminals for group use.
By 1970, the company had sales of and 1,400 employees. They began manufacturing in 1974, copying the already popular Xerox Redactron word processor, a single-user, cassette-based product.
In 1976, they started marketing a multi-user, display-based product, based on the Zilog Z80 processor. Typical installations had a master unit (supplying disk storage) connected to intelligent diskless slaves which the operators used. Connections were via dual coax using differential signaling in an 11-bit asynchronous ASCII format clocked at 4.275 MHz. This product became the market leader in the word processing industry. In addition to calculators and word processors, Wang's company diversified into in the early 1970s. The Wang 2200 was one of the first desktop computers with a large CRT display and ran a fast hardwired BASIC interpreter. The Wang VS system was a multiuser minicomputer whose instruction set was very close to the design of IBM's System/370. It was not binary-compatible because register usage conventions and system call interfaces were different. The Wang VS serial terminals could be used in data processing mode and word processing mode. They were user-programmable in data-processing mode and used the same word processing software as the earlier dedicated word processing systems.
In 1984, Wang and his family owned about 55 percent of the company stock, and Forbes magazine, estimating his worth at , ranked him as the fifth richest American.
Wang Laboratories, which in 1989 once employed over 30,000 people, was headquartered in Tewksbury, Massachusetts and later Lowell, Massachusetts. When Wang looked to retire from actively running his company in 1986, he insisted upon handing over the corporate reins to his son Fred Wang. Hard times ensued for the company and the elder Wang was eventually forced to remove his son in 1989.
An Wang also made a substantial contribution for the restoration of a Boston landmark, which was then called the Metropolitan Theatre. The "Met" was renamed in 1983 as The Wang Theatre, and the Metropolitan Center became known as the Wang Center for the Performing Arts. Wang donated $4 million to Massachusetts General Hospital's ambulatory care center, which was renamed to the Wang Building.
Wang was one of twelve recipients of the Medal of Liberty in 1986. He was inducted into the National Inventors Hall of Fame in 1988. The An Wang Middle School in Lowell, Massachusetts, is named in his honor, as is the An Wang Professorship of Computer Science and Electrical Engineering at Harvard University, held by Roger W. Brockett and Hanspeter Pfister, the An Wang Professorship of Computer Science at Brown University, held by John E. Savage, and the Wang Professorship of Cognitive and Neural Systems at Boston University, held by Stephen Grossberg; see sites.bu.edu/steveg.
An Wang died of cancer in 1990. He and his wife, Lorraine (Chiu) Wang, lived in Lincoln, Massachusetts. Lorraine Wang died on March 1, 2016, at Emerson Hospital in Concord, Massachusetts. They had three children.
