Goldin is often credited with inventing the sawing a woman in half illusion, however the first public presentation of this type of illusion was by British magician P. T. Selbit in 1921. Goldin presented his own version of the trick a matter of months later. There remains a debate about the origin of the idea, with some sources saying a magician named Torrini may have performed the first version in front of Pope Pius VII in 1809. It has also been suggested that the trick can be traced back to ancient Egypt. However, there is a lack of solid and available evidence for these claims. There seems to be broad agreement that Selbit was the first to present the illusion on stage and that Goldin achieved a place in history through subsequent technical development and promotion. Goldin's initial version was claimed as an improvement over Selbit's because the assistant's head, hands and feet remained visible during the sawing whereas Selbit's assistant was totally obscured from view inside a box. Goldin later devised a version that dispensed with a box entirely and used a large buzzsaw.
