Dr. An Wang (Chinese: 王安; pinyin: Wáng Ān; February 7, 1920 – March 24, 1990) was a Chinese American computer engineer and inventor, and co-founder 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.
A native of Kunshan County in Suzhou Prefecture, he was born in Shanghai, China, and graduated from Jiao Tong University with a degree in electrical engineering in 1940. He immigrated to the United States in June 1945 to attend Harvard University for graduate school, earning a PhD in applied physics in 1948. After graduation, he worked at Harvard with Dr Howard Aiken on the design of the Mark IV, Aiken's first fully electronic computer. Wang co-invented the pulse transfer controlling device with Way-Dong Woo, a schoolmate from China who fell ill before their patent was issued. The new device implemented write-after-read which made magnetic core memory possible. Harvard reduced its commitment to computer research in 1951, prompting Wang to start his own engineering business.
