Born in
London, he was the eldest son of
Sydney William Herbert Pierrepont, 3rd Earl Manvers. He was educated at
Eton, and was styled by the
courtesy title of
Viscount Newark from 1860 until succeeded to his father's peerage in January 1900. Newark was a sub-lieutenant in the
Grenadier Guards from 1872 until retiring in 1880, and subsequently held a variety of positions in the
Yeomanry and
Volunteers: captain in the
South Nottinghamshire Yeomanry Cavalry; major in the 2nd Volunteer Battalion (later 8th Bn),
Sherwood Foresters) and honorary colonel from 1904; colonel commanding the
North Midland Brigade 1896–1908. In November 1901 he received the
Volunteer Officers' Decoration (VD) for his contribution to the North Midlands Infantry Volunteers. He was elected at the
1885 general election as the
Member of Parliament (MP) for the
Newark division of
Nottinghamshire. He was re-elected unopposed in
1886 and
1892, and stood down at the
1895 general election. However, his Conservative successor
Harold Heneage Finch-Hatton resigned in 1898, and Viscount Newark was returned unopposed at the resulting by-election. He held the seat until his succession to the peerage in 1900. The 4th Earl was a keen sportsman and was Master of the
Rufford Hunt from 1900. ==Family and children==
