Historical Significance: Harry Moss Traquair (1875-1954) was Scottish and is regarded as the father of clinical perimetry. His name is attached to some visual field concepts such as Traquair's hill of vision, Traquair's perimetric targets and Traquair's scotoma. He published a classic book on visual fields in 1927, of which there were 5 later editions, some re-issued by US publishers. The last edition was published posthumously in 1957, when it was titled 'Traquair's Clinical Perimetry' and co-authored by G I Scott. See Cat No 338 and 736.Newey Brothers Ltd of Birmingham was established by Richard Newey in Birmingham in 1798. In the 1930s and 40s the company advertised as manufacturers of metal smallware including press buttons, hairpins, corset garter and suspender fittings, buckles and hair grips. Newey Brothers traded until at least the 1970s.
