The search of a straight-line mechanism

During the centuries, the problem to describe a straight line was one that tickled the fancies of mathematicians, of ingenious mechanics, and of gentlemanly dabblers in ideas. Sir Alfred Bray Kempe was a mathematician  who discovered (in 1877) new straight line linkages and published his influential lectures on the subject.
