observatory, owned and operated by the University of California. It is situated on the summit of Mount Hamilton, in the Diablo Rangejust east of San Jose, California, USA. The observatory is managed from the University of California, Santa Cruz, where its scientific staff moved in the mid-1960s.
Lick Observatory was the world's first permanently occupied mountain-top observatory [ [http://mthamilton.ucolick.org/public/history/bldg_the_obs.html The Building of Lick Observatory] ] .
The observatory was constructed between 1876 and 1887, from a bequest from
James Lick. In 1887 Lick's body was buried under the future site of the telescope, with a brass tablet bearing the inscription, "Here lies the body of James Lick."
Before construction could begin, a road to the site had to be built. All of the construction materials had to be brought to the site by horse and mule-drawn wagons, which could not negotiate a steep grade. To keep the grade below 6.5%, the road had to take a very winding and sinuous path, which the modern-day road (SR 130) still follows. Tradition maintains that this road has exactly 365 turns. (This is approximately correct, although uncertainty as to what should count as a turn makes precise verification impossible). Even those who do not normally suffer from motion-sickness find the road challenging. The road is closed when there is
snowat Lick Observatory.
The 36 inch (91.44-cm)
refracting telescopeon Mt. Hamilton was Earth's largest refracting telescope during the period from when it saw first lighton January 3, 1888, until the construction of Yerkes in 1897. In April, 1888, the observatory was turned over to the Regents of the University of California, and it became the first permanently occupied mountain-top observatory in the world. Edward Singleton Holdenwas the first director. The location provided excellent viewing performance due to lack of ambient light and pollution; additionally, the night air at the top of Mt. Hamilton is extremely calm, and the mountain peak is normally above the level of the low cloud cover that is often seen in the San Jose area. When low cloud cover is present below the peak, light pollution is cut to almost nothing.
With the growth of San Jose, and the rest of Silicon Valley,
light pollutionbecame a problem for the observatory. In the 1970s, a site in the Santa Lucia Mountainsat Junípero Serra Peak, southeast of Monterey, was evaluated for possible relocation of many of the telescopes. However, funding for the move was not available, and in 1980 San Jose began a program to reduce the effects of lighting, most notably replacing all streetlamps with low pressure sodium lamps. The result is that the Mount Hamilton site remains a viable location for a major working observatory. Asteroid 6216 San Jose was named in honor of the city's efforts to reduce light pollution by the International Astronomical Union.

In 2006, there are 23 families in residence, plus typically between two to ten visiting astronomers from the University of California campuses, who stay in dormitories while working at the Observatory. The little town of Mount Hamilton atop the mountain has its own police and a post office, and until recently a one-room schoolhouse.
In 2008, there are 38 people residing on the mountain, the chef and commons dinner were decommissioned earlier in the year.
