Chabot Space & Science Center Since 1883

The original Chabot Observatory was built in 1883 by Anthony Chabot. It was equipped with an 8-inch equatorial refractor by Alvan Clark & Sons, a 4-inch double pier transit and meantime clock by Fauth & Co., a Howard sidereal clock, a Negus Break Circuit chronometer, and a chronograph.

The observatory was given to the Board of Education in trust for the City of Oakland and was to be forever free to the public and the public schools.

Chronology

1882

    The new superintendent of the Oakland School District, James C. Gilson, resolves that the district should have a fine telescope such as the one he had seen at the Philadelphia High School.

1883

    Anthony Chabot, successful hydraulic engineer and provider of water to the city, agrees first to fund an 8-inch telescope, and subsequently funds the new observatory as well, which opens in downtown Oakland on November 24th.

1885

    Chabot further funds a Fauth Transit Telescope with its opportunant chronometers and sideral clocks. This telescope establishes the correct time by measuring the passage of stars across its axis, and was used to set the official local time.

1888

    Anthony Chabot dies, endowing the Observatory, which now assumes his name.

1915 - 1929

    A new Observatory is built on a low hill, about five miles east of City Hall, and equipped with the existing telescope plus a new 20-inch instrument commissioned in 1914 from Warner & Swasey, with optics by John Brashear. This is the current observatory on Mountain Boulevard.

1924

    The East Bay Amateur Astronomical Association, now known as the Eastbay Astronomical Society (EAS), is founded at the new Observatory. The Association makes the Observatory the focus of a great deal of innovative and enthusiastic scientific activity.

1960 - 1964

    Physics and biology programs are moved to the site, and a new planetarium is built and equipped by four Oakland Rotary Clubs. Kingsley Wightman is put is charge of the astronomy/space sciences classes.

1976

    After several years of discussions a site planning committee recommends a new site at elevation 1,540 feet several miles away.

1977

    As the current observatory sits on the creep zone of the Hayward Fault, a new law bans the use of the site by school classes.

1980 - 1986

    The Board of Education votes to support relocation, and the concept of a new Science Center operated by a new foundation begins to grow.

1989

    The creation of the Chabot Observatory & Science Center (COSC) as a Joint Powers Agency is approved by the City of Oakland, the East Bay Regional Park District, and the Oakland Unified School District, in conjunction with the Eastbay Astronomical Society. This resolution creates a new steward for the Chabot endowment, to which the founding authorities can turn over assets. In the meantime, maintenance at the present site has been delayed, and the physical condition of the buildings becomes even more critical.

1991

    Dr. Michael Reynolds becomes the first Executive Director of COSC.

1992

The Chabot Observatory & Science Center Foundation is established as a nonprofit organization.

1993

    The architectural firms of Gerson/Overstreet and Fisher-Friedman Associates are retained to prepare the Master Plan and to design the new facility.

1994

    A contract with the United States Air Force provides a construction grant of $17 million.

1996

A ground-breaking ceremony is held in October on the site in the Oakland hills.

1998

Construction of the new Science Center begins in May.

2000

    Chabot Observatory & Science Center changes its name to Chabot Space & Science Center.

    On August 19, Chabot Space & Science Center opens to the public. The state-of-the-art Science Center features the Chabot telescopes, the Ask Jeeves Planetarium, Tien MegaDome theater, hands-on interactive science and technology exhibits, teacher training and student labs, and public science programs.
