How many storeys does this tower house have which David Gregory inherited in 1664?
David Gregory (physician) David Gregory (20 December 1625 – 1720) was a Scottish physician and inventor. His surname is sometimes spelt as Gregorie, the original Scottish spelling. He inherited Kinnairdy Castle in 1664. Three of his twenty-nine children became mathematics professors. He is credited with inventing a military cannon that Isaac Newton described as "being destructive to the human species". Copies and details of the model no longer exist. Gregory's use of a barometer to predict farming-related weather conditions led him to be accused of witchcraft by Presbyterian ministers from Aberdeen, although he was never convicted.
Ingram House Ingram House is a historic building in the district of Bootham, York, England. It was built as an almshouse for ten poor widows between 1630 and 1640 by real estate developer and politician Sir Arthur Ingram and was originally known as Ingram's Hospital. It was damaged during the Siege of York and was restored in 1649. It is the most important mid-seventeenth century building in Bootham, pre-classical and composed of eleven bays of two low storeys, but with a four-storey central tower. The middle doorway dates back to the Norman period, and is believed to have once been a doorway to Holy Trinity Priory.
