Lettice Ramsey (2 August 1898 – 12 July 1985) was a British photographer.

Lettice Cautley Baker was born on 2 August 1898 in Guildford, Surrey, England. Her father Cecil was a surveyor and her mother Frances (née Davies-Colley) was a painter, trained at the Slade.^[1] The Baker family moved to County Sligo, Ireland, soon after Lettice's birth, where Cecil Baker had leased rights to oyster farming in the estuary near Rosses Point.^[2] Ramsey's father died when she was a small child; her mother remarried in 1915.^[1] She attended Bedales, then Newnham College, Cambridge, where she studied philosophy.^[3] After working for a brief time in vocational guidance in London, she returned to Cambridge to work in the Psychology Library.^[4] In 1925, she married mathematician Frank P. Ramsey, and they had two daughters before his early death in 1930 from liver disease.^[3]

To support her family, Ramsey took a photography course at Regent Street Polytechnic.^[3] Introduced to photographer Helen Muspratt by artist F. H. "Fra" Newbery, the two women opened a studio together in Cambridge in 1932.^[5]

Lettice Ramsey died on 12 July 1985 in Cambridge, England.

The photography studio, Ramsey & Muspratt, was a successful commercial venture, and the pair photographed influential social, academic, and artistic figures in Cambridge throughout the 1930s.^[6] Muspratt moved to Oxford in 1937 and opened a second studio there; Ramsey maintained the studio in Cambridge, and both retained the Ramsey & Muspratt studio name. They remained close throughout their lives.^[7] In the 1930s, the Ramsey & Muspratt studio was noted for using the solarization process in some portrait work;^{[8][citation needed]} two of the firm's photographs were accepted in the London Salon of Photography in both 1936 and 1937.^[9] While Ramsey's Cambridge work was primarily portraiture, she photographed on her travels, including Russia in 1933, an around-the-world trip in 1948, and later travel to Nepal, Australia, New Zealand, Fiji and Mexico. She visited Cambodia in the late 1960s.^{[10][citation needed]}

Fourteen of Ramsey's portraits of the Bloomsbury Group were published in a calendar by the Charleston Trust in 1990.^[11] In 2012–2013, the National Portrait Gallery, London presented an exhibition of Ramsey & Muspratt work exploring Ramsey's friendship with the Bloomsbury Group poet Julian Bell.^[12]

Ramsey retired in 1978.
