He was friends with many prominent people, such as Charles Dickens, Thomas Carlyle, Sir John Herschel and Charles Darwin. He held regular Saturday evening parties at his home in Manchester Square for many years, which were apparently attended by two or three hundred people and were said to be a meeting place for Europe's liberal intelligentsia. This series contains a letter from Joshua Field as well as correspondence from (Augusta) Ada King, Countess of Lovelace (Byron's daughter). Other correspondents include the Duchess Dowager of Somerset, the scientist Sir Charles Wheatstone, writer and statesman Edward Bulwer-Lytton, Admiral Edward Codrington, politician Henry Bougham, heiress and philanthropist Baroness Angela Georgina Burdett-Coutts, actor William McCready, scientific writer John Peter Gassoit and the civil engineer Isambar Kingdom Brunel. Many of the letters are invitations to social events.

Description: Correspondence, letters, invitations and documents (168), to Charles Babbage, Charles Babbage/Neville Babbage, England/Australia, 1827-1869

This series contains correspondence to Charles Babbage. The letters provide evidence of his interests and social connections. Babbage was a well known figure in London society. He was friends with many prominent people such as Charles Dickens, Thomas Carlyle, Sir John Herschel and Charles Darwin. He held regular Saturday evening parties at his home in Manchester Square for many years, which were apparently attended by two or three hundred people and were said to be a meeting place for Europe's liberal intelligentsia. The writers of the letters include many distinguished scientists, writers, society people and other well-known people who were part of Babbage's extensive range of friends and acquaintances. Authors include Sir John Franklin (explorer), George Grote (historian), Abraham Hayward (essayist), JW Lubbock (astronomer and mathematician), and Benjamin Brodie (surgeon). The letters are generally brief and relate to social engagements, receipt or return of publications, and personal matters. There is a letter from James Bicheno (Colonial Secretary, Van Diemen's Land) thanking Babbage for 'valedictory remembrances' on going to the other side of the globe, 1846, and a letter from the Duke of Newcastle (Secretary of the State for the Colonies) regarding a recommendation for the appointment of Babbage's son as Master of the Mint in Melbourne, 1860. There is an unsigned and undated document about a dinner party organised by the Duchess of Somerset which is believed to be in Charles Babbage's handwriting.

The letters and invitations have been kept separately by Neville Babbage. He has numbered them in pencil and often written the name of the author on the letter. This order has been maintained.
