In 1832, Mussoorie was the intended terminus of the Great Trigonometric Survey of India that began at the southern tip of the country. Although unsuccessful, the Surveyor General of India at the time, George Everest, wanted the new office of the Survey of India to be based in Mussoorie; a compromise location was Dehradun, where it remains.[citation needed] The same year the first beer brewery at Mussoorie was established by Sir Henry Bohle as "The Old Brewery". The brewery opened and closed twice before it was re-established by Sir John Mackinnon as Mackinnon & Co. in 1850.[5]
