Son of Sir John Rushout, 5th bt. and 1st baron Northwick [1738-1800] and his wife Rebecca [d. 1818], daughter of Humphrey Bowles of Wanstead, county Essex. The 2nd baron was Governor of Harrow School from 1801 until his death, once wrote a 55 page pamphlet about his dispute with local authorities over a threshing machine, and gathered a splendid art collection, first displayed at the family home of Northwick Park, near Moreton-in-the-Marsh, Worcestershire (now Gloucestershire). He died unmarried and was succeeded by his nephew, Sir George Rushout, the son of his brother George [1772-1842]. G.F. Waagen, in Treasures of Art in Great Britain, London, 1854: III:195+, described Baron Northwick's collection of over 800 pictures at Thirlestane House, near Cheltenham, which had been built especially to house it after it outgrew Northwick Park. This enormous collection was sold at Phillips, London, from 26 July - 30 August 1859.
