Friedrich von Knaus(s) (February 7 or April 7, 1724 - August 14, 1789), was a German watchmaker and inventor who built clockwork mechanisms which could, in a simple way, play musical instruments, write short phrases, or conduct other individual, specialized tasks. Von Knauss was born either in Aldingen or in Ludwigsburg. His father, Ludwig Knaus, was also a watchmaker. Friedrich had a brother, Ludwig Johann, whose year of birth is said to have been 1715 or 1716. In 1778, Knauss was requested as a captain to the artillery of Vienna, where he died.
