ESTC Citation Nos. T77181 and T77180. Like his fellow County Durham savant John Bird, the astronomer and instrument designer, Emerson makes a fictional appearance in Thomas Pynchon's ‘Mason and Dixon.' He was the very archetype of the English eccentric: According to an Age of Enlightenment account, Emerson dressed in old clothes and his manners were uncouth. He wore his shirt back to front and his legs wrapped in sacking so as not to scorch them as he sat over the fire. He complained about the expense of all the candles he had used during a lifetime studying mathematics, mechanics (he apparently never advanced a proposition he had not tested, nor published an invention without first proving its effects by a model), and music, including the theory of sounds and the ancient and modern scales. He died on 20 May 1782 at his small estate in Weardale, where his gravestone bears epitaphs in Latin and Hebrew. N. B.
