Francis John Henry Jenkinson (20 August 1853 – 21 September 1923) was librarian of the University of Cambridge 1889–1923.
Whilst librarian at Cambridge, Jenkinson oversaw the acquisition of various collections, including Lord Acton's library and material from the Cairo Genizah.
[4][2] During World War I he began what is known as the War Reserve Collection, which includes unofficial and personal items and ephemera such as flyers, cards and journals as well as public school rolls of honour and weekly casualty lists.
[1] In 2023, the centenary of his death, a full-day symposium in his honour was held at Cambridge University Library.
Entitled ‘The Care of Books Is a Difficult Business’, it featured scholarly papers on Jenkinson’s life, work, and connections,[7] along with displays of Jenkinsoniana and of John Singer Sargent’s portrait of Jenkinson.
