Treasurer’s House can be found on Minster Yard from where John Goodricke observed the star Algol in 1782. The brightness of Algol was known to change in a predictable way. Encouraged by his friend Edward Pigott, a local amateur Astronomer, deaf Goodricke discovered it was actually a double star, and the light from one star was reduced as the other passed in front of it. The splendid view of the Minster from the house would have allowed the Central Tower to be used as a stationary point on which to measure the movement of stars. For this work he was awarded a Copley Medal by the Royal Society. Tragically Goodricke died young, aged only 21, but his thinking still influences astronomers today.
