Isaac Newton Wallop, 5th Earl of Portsmouth DL JP^[1](11 January 1825 – 4 October 1891) was a British Peer and the son of Newton Fellowes, 4th Earl of Portsmouth and Lady Catharine Fortescue.^[2]

Early life

Portsmouth was born as Isaac Newton Fellowes, but later resumed the family surname and arms of Wallop without Royal Licence when he succeeded to the peerage in 1854.^[2][3] He was the son of Newton Fellowes, 4th Earl of Portsmouth and Lady Catharine Fortescue, daughter of Hugh Fortescue, 1st Earl Fortescue.

He was educated at Rugby School and matriculated at Trinity College, Cambridge,^[4] where he received a Master of Arts degree.

Newton Papers

In 1872 Lord Portsmouth donated to his alma mater, Trinity College, Cambridge, a vast collection of papers by Sir Isaac Newton which had descended through Newton's great-niece Catherine Conduitt, daughter of John Conduitt and Catherine Barton, into the Wallop family by her marriage to John Wallop, Viscount Lymington.^[5][6]

A committee chaired by John Couch Adams and Sir George Stokes was appointed by the University to review the papers. Adams and Stokes selected only Newton's scientific papers, not wanting to blemish his reputation as an enlightened intellectual and scientist. After spending sixteen years cataloging Newton's papers, Cambridge University kept a small number and returned the rest to the Earl of Portsmouth.^[7]

Marriage and issue

On 15 February 1855, Lord Portsmouth married Lady Eveline Alicia Juliana Herbert (21 December 1834 – 1 October 1906), daughter of Henry John George Herbert, 3rd Earl of Carnarvon, by his wife, Henrietta Anna Howard, daughter of Lord Henry Thomas Howard-Molyneux-Howard (yr. brother of Bernard Howard, 12th Duke of Norfolk).^[2][3] They had twelve children:
