A collection of roughly 300 negatives, most used to make microphotographs by J B Dancer of Manchester between c1853 and 1878, and then by his daughters E E and A M Dancer until the sale of the business to Richard Suter in 1896. The negatives are accompanied by documents relating to the 1896 sale of the business to Suter, research notes compiled by Arthur Barron, and publications created by the Royal Photographic Society Historical Group about Dancer and his microphotographic technique.
