Mt Hamilton History Nuggets

• Mt Hamilton was named for Reverend Laurentine Hamilton after he won a race to the summit with a botanist named Wiliam Brewery from the CA Geological Survey in 1861.

• Mt Hamilton is part of the Mt Diablo Mountain Range in which our own Mt Diablo is at the northernmost end.

• The observatory was constructed between 1876 and 1887, from a bequest from James Lick (1796 – 1876) of $700,000. Lick, originally a carpenter and piano maker, chose the site atop Mount Hamilton and was buried there in 1887 under the future site of the telescope, with a brass tablet bearing the inscription, "Here lies the body of James Lick”. When he died he was the wealthiest Californian.

• 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. Tradition has it that the road has exactly 365 turns.

• The observatory was established in 1888. It has been managed by the University of California since its inception.

• The first new moon of Jupiter to be identified since the time of Galileo was discovered at this observatory in 1892; Amalthea, the planet's fifth moon.

• The asteroid 452 Hamiltonia, discovered in 1899, is named after the mountain.

• In 1950, the California State legislature appropriated funds for a 120-inch (300-centimeter) reflector telescope, which was completed in 1959.

• Claire Max, of the Lawrence Livermore National Laboratory, led the team that built the adaptive optic system and sodium laser guide star for Lick Observatory.
