Sir Joseph Cockfield Dimsdale, 1st Baronet, KCVO, PC (19 January 1849 – 9 August 1912) was a distinguished public figure in the late nineteenth and early twentieth centuries.
Dimsdale was born in Cornhill on 19 January 1849, the eldest son of Joseph Cockfield Dimsdale of Cleveland Square, London, and educated at Eton. His father was from an old Quaker family with roots in Essex, and he was related to the physician and politician Thomas Dimsdale (1712-1800).
Dimsdale was the Managing Director of Prescott, Dimsdale and Co, bankers. He was Alderman of Cornhill from 1891 to 1902, was elected Sheriff of London for 1893, and Lord Mayor of London in September 1901 (serving November 1901 to November 1902). He was a leading member of the Grocers' Company, of which he was for a time Master. In the 1900 general election, he was elected as the Member of Parliament (MP) for the City of London, and served one term until 1906.
He was knighted in 1894, in commemoration of the opening of the Tower Bridge and birth of an heir to the Throne while he was Sheriff. In 1902 he carried the Crystal Sceptre of the City of London in front of King Edward VII at his Coronation. The ceremony was re-scheduled from June to August, due to the King´s illness, but the 1902 Coronation Honours list was released on the intended coronation day on 26 June 1902, and announced that Dimsdale would receive a baronetcy. He was created Baronet, of Goldsmiths, Langdon Hills, in the County of Essex and of Lancaster Street in the Borough of Paddington in the County of London, on 24 July 1902. Later that year he was appointed a Knight Commander of the Royal Victorian Order (KCVO) in the November 1902 Birthday Honours list.
