Throughout the 19th century and well into the 20th century, a wide range of hats was manufactured to suit all tastes and purses. The names used by the competing manufacturers to describe their products was bewildering and some of these were; felt hats, silk hats, fur hats, wear fur hats, soft hats, stiff hats, velour hats, wool hats, straw hats and, of course, the ubiquitous cloth cap. In the 1930s the 'Attaboy' trilby hat was introduced by the Denton Hat Company. This brand quickly became famous and it was in production for many years. Ladies' hats were not forgotten either and at least one works specialised in making these and the hat master's wife designed them at home. Hats were made for home consumption and for export. The well-known slogan ""If you want to get ahead, get a hat"" arose in Denton and, needless to say, anyone attending for a job interview not wearing a hat was quickly shown the door. Similarly, until the early 20th century, anyone entering a Denton shop without a hat would receive much cursing. The term, ""mad as a hatter"" also arose in Denton because the mercury used in the felting process led to mercury poisoning.
