. It remained standard in western writing throughout the medieval period and was adopted in early printing with movable types. It existed alongside minuscule "round" or "short" ''s'', which was at the time only used at the end of words. In most Western orthographies, the ſ gradually fell out of use during the second half of the 18th century, although it remained in occasional use into the 19th century. In Spain, the change was mainly accomplished between 1760 and 1766. In France, the change occurred between 1782 and 1793. Printers in the United States stopped using the long ''s'' between 1795 and 1810. In English orthography, the London printer John Bell (1745–1831) pioneered the change. His edition of Shakespeare, in 1785, was advertised with the claim that he "ventured to depart from the common mode by rejecting the long 'ſ' in favor of the round one, as being less liable to error....."
