The museum's origins date to 1968 when Gordon Bell began a quest for a historical collection and, at that same time, others were looking to preserve the Whirlwind computer. The resulting Museum Project had its first exhibit in 1975, located in a converted coat closet in a DEC lobby. In 1978, the museum, now The Digital Computer Museum (TDCM), moved to a larger DEC lobby in Marlborough, Massachusetts. Maurice Wilkes presented the first lecture at TDCM in 1979 – the presentation of such lectures has continued to the present time.
In 1996/1997, the TCM History Center (TCMHC) was established; a site at Moffett Field was provided by NASA (an old building that was previously the Naval Base furniture store) and a large number of artifacts were shipped there from TCM.
In 1999, TCMHC incorporated and TCM ceased operation, shipping its remaining artifacts to TCMHC in 2000. The name TCM had been retained by the Boston Museum of Science so, in 2000, the name TCMHC was changed to Computer History Museum (CHM).
In 2002, CHM opened its new building, previously occupied by Silicon Graphics, at 1401 N. Shoreline Blvd in Mountain View, California, to the public.[1][2] The facility was later heavily renovated and underwent a two-year $19 million makeover before reopening in January 2011.[3]
John Hollar, a former media executive, was appointed CEO in July 2008.[4] Dan'l Lewin, a former technology executive, replaced Hollar as CEO in March 2018.[5]
The Computer History Museum claims to house the largest and most significant collection of computing artifacts in the world.[a] This includes many rare or one-of-a-kind objects such as a Cray-1 supercomputer as well as a Cray-2, Cray-3, the Utah teapot, the 1969 Neiman MarcusKitchen Computer, an Apple I, and an example of the first generation of Google's racks of custom-designed web servers.[7] The collection comprises nearly 90,000 objects, photographs and films, as well as 4,000 ft (1,200 m) of cataloged documentation and several hundred gigabytes of software.
The museum's 25,000 sq ft (2,300 m2) exhibit "Revolution: The First 2000 Years of Computing", opened to the public on January 13, 2011. It covers the history of computing in 20 galleries, from the abacus to the Internet. The entire exhibition is also available online.[9][10][11]
On January 28, 2017, the Museum launched a 6,000 sq ft (560 m2) exhibit "Make Software: Change the World!" The exhibit covers how people's lives are transformed by software. Designed for middle schoolers and up, it features multimedia and touchscreen interactives, including a software lab where visitors can explore coding hands-on.[12]
Other exhibits include a restoration of an historic PDP-1minicomputer, two restored IBM 1401 computers.
The CHM is also home to an extensive collection of software, curated by Al Kossow, a veteran of Apple Computer whom the museum hired in 2006. Kossow is responsible for preservation and accession of software in the museum, as well as for developing CHM's software-themed exhibitions. Kossow was a contributor to the museum long before being hired full-time and is the proprietor of Bitsavers, a large online repository of historical computer manuals and archived software and firmware acquired from his own collection and through donations from his peers.[14][15][16]
In 2010 the museum began with the collection of source code of important software, beginning with Apple's MacPaint 1.3, written in a combination of assembly language and Pascal and available as download for the public.[17][18]
On June 23, 1990, the Walk-Through Computer exhibit opened to help visitors learn how computers work.[27] The interactive exhibit included a desktop computer, a giant monitor, a 25-foot (7.6 m) keyboard, and a 40-inch (1,016 mm) diameter trackball (initially planned to be a "bumper-car sized mouse") used by visitors to control the World Traveler program. In the Software Theater, animation and hardware video is used alongside a video feed of the World Traveler Program to show how computer programs work.[28] This exhibit was closed on August 5, 1995, and re-opened as the Walk-Through Computer 2000 on October 21, 1995, to include an updated monitor, 3D graphics, and more interactive features. One of these features allowed visitors to change the pits imprinted on a giant CD-ROM, and the changes are seen on a monitor.[29]
In 2016 museum had a Liquid Galaxy in the "Going Places: A History of Silicon Valley" exhibit. The exhibit had 20 preselected locations that visitors can fly to on the Liquid Galaxy.[30] An exhibit on the history of autonomous vehicles, from torpedoestoself-driving cars was also on display.
The CHM Fellow Awards Program honors distinguished technology pioneers for their outstanding merits and significant contributions to the advancement of computing and the evolution of the digital age. The CHM Fellows are men and women 'whose ideas have changed the world [and] affected nearly every human alive today'. The first fellow was Rear Admiral Grace Hopper in 1987. The fellows program has grown to 100 members as of 2024.[31] Fellow nominations are open to the public and are accepted year round.[32]
