Early life and background
Harry Primrose was born in 1967, and is the son and heir of Neil Primrose, 7th Earl of Rosebery. He is a great-grandson of Prime Minister Archibald Primrose, 5th Earl of Rosebery, and Hannah de Rothschild, the richest woman in Britain. The earls of Rosebery own Dalmeny House and also owned Mentmore Towers until 1977.

He was educated at the Dragon School, Oxford, and Eton College. He then studied art history at Trinity College, Cambridge.

Career
Dalmeny joined Sotheby's in 1990 to work in the Country House sale department. In 2000, he became a director of Sotheby's and from 2003 to 2007 was chairman of Sotheby's Olympia. He also took on responsibility for the single-owner sales department in 2006 and became deputy chairman, Sotheby's UK in 2007. He became chairman of Sotheby's in 2017.

As Sotheby's director of country house sales in the UK, Lord Dalmeny has been behind the rostrum and on top of the gavel for some of the most high-profile auctions in Europe, including the Duke of Devonshire's sale at Chatsworth House and the 2004 record sale at Hopetoun House of Jack Vettriano's painting The Singing Butler for £744,800.

In 2013, Dalmeny rode in the Queen's carriage at Royal Ascot.

In 2014, the Primrose family sold the painting Rome, From Mount Aventine by J. M. W. Turner for £30.3m to fund restoration work on Dalmeny House. The painting, regarded as one of Turner's finest, had been bought by the future Prime Minister Archibald Primrose in 1878.

In 2019, Dalmeny presided over the auction of Claude Monet's 1890 painting Meules for US$110.7 million at Sotheby's New York, a record for an impressionist work.

In 2001, Dalmeny sold his inherited Gilbert Stuart's 1796 George Washington (Landsdowne portrait) to the National Portrait Gallery at the Smithsonian Institution where it had been on indefinite loan since 1968. To prevent his auctioning it at Sotheby's, a U.S. donor paid the US$20 million that Dalmeny had requested from the Gallery.

In 1994, Lord Dalmeny married Caroline Daglish, a former Conservative Party researcher working for Robert Jones MP and Lord Strathclyde. She is a Patroness of the Royal Caledonian Ball.
