Early life and education
Tyacke was born Sarah Jeacock in Chelmsford, Essex, on 29 September 1945: her father, grandfather and great-grandfather had all been school headmasters. She was educated at Chelmsford County High School for Girls, before studying history at Bedford College, University of London, and graduating in 1968. During vacations from 1962 to 1968, she worked as a volunteer at Essex Record Office.

In 1968, Tyacke became an assistant keeper in the Map Room of the British Museum. From 1973 to 1985 she was Deputy Map Librarian in what had now become the British Library; and from 1986 to 1991 she was its director of special collections.

At the end of 1991 she was appointed keeper of public records, the first woman to hold the post. Her tenure at the Public Record Office included the building of a much expanded repository on the office's site at Kew in 1995, and subsequent removal of services from the old Public Record Office building in Chancery Lane; the opening of a Family Records Centre for family historians in 1997; and merger of the office with the Royal Commission on Historical Manuscripts in 2003 to form the National Archives. At the merger, Tyacke was appointed its chief executive and sole historical manuscripts commissioner. She also oversaw numerous technical initiatives, including the launch of the 1901 census website as a pay-per-view service in 2002 and development of strategies for preserving born-digital records. She retired in 2005.
