The House of Gauss

Carl Frederick Gauss is one of Germany's most famed scientists. His mathematical, physical and astronomical theories are still being used today. In the later stages of his life he lived in what is now called the old Göttingen observatory.

It is said that Gauss hated living inside the city as he was not really the biggest people person and was very tired of all the obligations that came with his stature. In the later stages of his life he lived in the observatory and is known to have said that he loved it. At this time the city gates would still close at night and he had the perfect excuse not to come to all these social events. 

The house is currently in use as a normal living house with a shop at the bottom. A plaque tells passersby that Gauss lived here, but you can't enter, sadly.
