I’ve known Ruth Harman for a long time, ever since she worked in Sheffield Archives and patiently tutored me when I knew even less about historical research than I do now.
Latterly she went on to co-write, with John Minnis, the Pevsner City Guide for Sheffield (Yale University Press 2004): https://www.amazon.co.uk/Sheffield-Pevsner-City-Guides-Architectural/dp/0300105851/ref=sr_1_1?ie=UTF8&qid=1509034870&sr=8-1&keywords=Pevsner+City+Guide+Sheffield.
In recent years I’ve occasionally encountered her, notepad in hand, investigating historic buildings across the former West Riding in preparation for her edition of Pevsner’s Buildings of England: West Riding: Sheffield and the South (Yale University Press 2017): https://www.amazon.co.uk/Yorkshire-West-Riding-Sheffield-Architectural/dp/0300224680/ref=sr_1_1?ie=UTF8&qid=1509032022&sr=8-1&keywords=Pevsner+West+Riding+South.
It’s apparent that you turn up all sorts of strange facts when you revise a Pevsner: Ruth once proudly told me that she’d found a lighthouse in the landlocked West Riding: http://www.geograph.org.uk/photo/1971566.
I was privileged to attend the launch of Ruth’s book at Wentworth Woodhouse in September, and it was only when I handled a copy that I realised the scale of her achievement. Sir Nikolaus Pevsner himself, in 1959, covered the whole of the West Riding in 610 pages; a revision by Enid Radcliffe seven years later added forty-two more pages.
Ruth’s 841 pages cover, in much more detail, only the southern half of the old West Riding, from the southern boundary of Sheffield to the outskirts of York, and from Blackshaw Head near Todmorden in the west to Adlingfleet, beyond Goole in the east.
(The equivalent volume for the northern half of the West Riding was published in 2009: https://www.amazon.co.uk/Yorkshire-West-Riding-Architectural-Buildings/dp/0300126654/ref=sr_1_1?s=books&ie=UTF8&qid=1509032672&sr=1-1&keywords=Pevsner+West+Riding+North.)
The invitation to the book launch also gave me the opportunity of a conducted tour of Wentworth Woodhouse where, for the first time in all the years I’ve known the building, back to when it was a teacher-training college, I set foot in the formerly private West Wing, the so-called “Back Front”.
