Alice's contribution to local history cannot be overstated," says Frank Woolrych, custodian of the Longstaff Collection and who has made it his life's work to keep her priceless bequest to the valley in the public eye.
"Apart from her gifts as a social photographer she was, fortunately, a great hoarder and kept everything, from the studio's own pictures and others acquired over the decades, to cameras, glass plates, brass-barrelled lenses and film-based negatives."
Frank is currently engaged in the marathon task of cataloguing each and every item - "there are thousands of images," he admits, "each one telling a human story about this area.
"At the time her career began in 1921 photography had a particular importance for people. There was a sense of mystery about the relationship between camera and subject and what went on beneath that black cloth. Now it tends to be taken for granted."
A modest, if strong-minded woman, she would be amazed at the attention she is attracting today - but would secretly be delighted, he adds.
Together with Issy Shannon, previously a reporter on the Hebden Bridge Times which ran a weekly feature on the Collection for several years, Frank has set up Milltown Memories, a quarterly magazine - "the Upper Calder Valley captured on camera, featuring photographs from the Longstaff Collection."
It is the voice-piece of the Collection and is an important part of the quest undertaken by Frank and fellow trustees Beryl Woolrych (Frank's wife and constant support) and Lloyd Greenwood (well known throughout the Hebden Royd area as raconteur and expert on local history) to eventually find a permanent home for Alice's remarkable legacy.
Part of the proceeds from "Alice's Album" will go towards acquiring equipment vital for maintaining and continuing support for the Collection.
