Thomas Leverton Donaldson

Thomas Leverton Donaldson (19 October 1795 – 1 August 1885) was a British architect, notable as a pioneer in architectural education, as a co-founder and President of the Royal Institute of British Architects and a winner of the RIBA Royal Gold Medal.

Donaldson was born in Bloomsbury Square, London, the eldest son of architect, James Donaldson. His maternal uncle was Thomas Leverton (1743–1824), a distinguished architect sometimes credited with the south range of Bedford Square in London.

Donaldson travelled overseas after leaving school, obtaining a clerical job with a merchant on the Cape of Good Hope before volunteering for an expedition to attack the French-controlled island of Mauritius. Once back in London, he was employed in his father's office, before visiting Italy and Greece to broaden his experience. His first significant work was the church of Holy Trinity in South Kensington, London (built 1826-1829).

With Jacques Ignace Hittorff and Charles Robert Cockerell, Donaldson was also a member of the committee formed in 1836 to determine whether the Elgin Marbles and other Greek statuary in the British Museum had originally been coloured (see Transactions of the Royal Institute of British Architects for 1842).

Donaldson reworked substantial sections of the Wilkins building at University College London (UCL), and designed its Flaxman Gallery and library buildings. He also designed All Saints Church in Gordon Street, London, and was involved with the Great Exhibition of 1851.
