The reef knot (square knot) with both ends slipped is called a bow knot (shoelace knot).

If you click through to the page about the “standard shoelace knot” it adds: “This knot appears in The Ashley Book of Knots as #1212 and #1214, ‘The Bowknot’, where it is described as ‘... the universal means of fastening shoe-strings together.’” (That’s a reference book from the 1940s https://en.wikipedia.org/wiki/The_Ashley_Book_of_Knots)
Edit: note that this is a site aimed at an audience of people who want to tie their shoes, not topologists or sailors. Pedantic arguments about acceptable definitions of the word “knot” are ridiculous in this context.

It says so in the first line. How can you be the inventor of an existing knot?
