1808 - 1882
Obituary by P G Tait:
"Listing introduces the theories of double-threaded screws and
paradromic winding. A special example of these, given by Listing for threads,
is the well-known juggler's trick of slitting a ring-formed
band up the middle, through its whole length, so that instead
of separating into two parts, it remains in a continuous
ring. For this purpose it is only necessary to give a strip
of paper one half-twist before pasting the ends together.
If
three half-twists be given, the paper still remains a
continuous band after slitting, but it cannot be opened into
a ring, it is in fact a trefoil knot."
