Life and work
John Goodricke, named after his great grandfather Sir John Goodricke 1617–1670 (see Goodricke baronets of Ribston Hall), was born in Groningen in the Netherlands, but lived most of his life in England. He became deaf in early childhood due to a severe illness. His parents sent him to Thomas Braidwood's Academy, a school for deaf pupils in Edinburgh, and in 1778 to the Warrington Academy.
After leaving Warrington, Goodricke returned to live with his parents in York. There, he became friends with his neighbour Edward Pigott, whose father Nathaniel Pigott had built a sophisticated private observatory. Edward was already interested in variable stars, and he gave Goodricke a list of those that he thought were worthy of observation.
Although several stars were already known to vary in apparent magnitude, Goodricke was the first to propose a mechanism to account for this. He suggested that Algol is what is now known as an eclipsing binary. He presented his findings to the Royal Society in May 1783, and for this work, the Society awarded him the Copley Medal for that year. He was elected a Fellow of the Royal Society on 16 April 1786. He never learned of this honour however, as he died four days later from pneumonia. He never married.
Goodricke in Yorkshire
Today there is a marker in York near the site of John Goodricke's observatory.
Between October 2005 and March 2006 Sean Ellingham and James Valner from the University of York undertook a project to find the position of Goodricke's observatory using the data he recorded. A 1949 study by Sidney Melmore had shown that Goodricke worked from the Treasurer's House (now owned by the National Trust) very near York Minster. By re-creating Goodricke's observations, the two York students were able to conclude that he had observed from the eastern-most window of the second floor, looking south towards the Minster. However, records indicate that the Goodricke family had rented rooms from Edward Topham, the then owner of the northwest wing of the house.
Asteroid 3116 Goodricke is named for John Goodricke.
The University of York has a Goodricke College named after John Goodricke.
The Goodricke-Pigott Observatory is a private astronomical observatory in Tucson, Arizona, named after the two late-eighteenth century astronomers and friends who lived in York, England, John Goodricke and Edward Pigott. It was formally dedicated on 26 October 1996, and observations began that evening with imaging of Comet Hale–Bopp.
In 2012 a non-profit organisation named after John Goodricke was established in Armenia by a group of amateur astronomers.
In 1984 a planetarium show about John Goodricke was created specifically for deaf students by the HOSS Planetarium.
