From the Guardian (hat tip: Chris Berard):

Antonia Gransden, who has died aged 91, was among the foremost medievalists of her generation. Her substantial and sustained scholarship spanned seven decades and continues to guide today’s students and researchers.

She will be best remembered for her two-volume, 1,000-page survey Historical Writing in England (1974, 1982), which covers the period from circa 550 to the early 16th century, from Gildas the Wise to Thomas More. Before that work anyone going in search of the roots of medieval historiography faced churning through the 250 volumes of the Stationery Office Rolls Series, or else had to find and translate the original parchment.

I was lucky to acquire both volumes of Historical Writing in England – it is certainly a very useful work.
