Mechanical Duplicators
Until the late 18th century, if an office wanted to keep a copy of an outgoing letter, a clerk had to write out the copy by hand. This technology continued to be prevalent through most of the 19th century. For this purpose offices employed copy clerks, also known as copyists, scribes, and scriveners.
A few alternatives to hand copying were invented between the mid-17th century and the late 18th century, but none had a significant impact in offices.

Famous quotes containing the word mechanical:
“We are caught up Mr. Perry on a great wave whether we will or no, a great wave of expansion and progress. All these mechanical inventions—telephones, electricity, steel bridges, horseless vehicles—they are all leading somewhere. It’s up to us to be on the inside in the forefront of progress.”
—John Dos Passos (1896–1970)
