William Lidderdale PC (4 July 1832 – 26 June 1902)[1] was a British merchant, and governor of the Bank of England between 1889 and 1892.

Barings became over-extended in underwriting Argentine debt, the value of which strongly declined following political unrest in Buenos Aires, and the recognition of the inefficient use of borrowed funds.

In recognition, he was granted the Freedom of the City of London and was made a member of the British Privy Council.

He became a commissioner of the Patriotic Fund in 1893, and held (among other financial offices) the presidency of the council of the Corporation of Foreign Bondholders.

[3] He married in 1868, Mary Martha, elder daughter of Wadsworth Dawson Busk of Winkfield.
