Like so many major observatories in the late nineteenth century, this one was made possible by a bequest from a very rich man.  In this case, James Lick, a successful businessman from the San Francisco Bay area.  When it became operational in 1888, the observatory housed the largest refracting telescope in the world, a magnificent instrument with a 36" diameter objective lens.  By the time the observatory was completed, James Lick was dead, and his body was placed in a permanent tomb at the base of the pier supporting the great telescope.  

          Over the years other telescopes have been located on the mountain.  The largest research instrument currently in use is a 120" reflector.  This latter instrument is historic in its own right, as it was one of the first telescopes used to collect the data which confirmed the existence of extra-solar planets.  The initial work was done in the late 1990s and continues today. 

The Great 36" Refractor

         Crossley Reflector

          This building houses a 36" reflecting telescope which was built in England in 1876 and acquired by Lick in 1898.  The building and the telescope has been nominated as a National Historic Landmark by the U.S. National Park Service, and full details on the history of the instrument are given on the website listed below.
