Ha ! I'll top that with a "Pascal Implementation: The P4 Compiler" two

I'm sure I remember a professor explaining that Pascal's text file
handling was like *that* so that it was possible/easy to write Pascal
compilers in Pascal, and that the first compiler for the CDC was
compiled by printing out two sets of the source code, laying them on
the floor side by side and manually running one with the other as input
...

"In 1969, a bootstrap compiler using Fortran as the implementation
language was completed. Although the compiler was written in Fortran,
the idea was to rewrite the compiler in Pascal itself, and so
bootstrap the compiler.
Wirth called that project unsuccessful, and instead, a Pascal compiler
was written in a subset of the full Pascal language and translated by
hand to a language called SCALLOP on the CDC 6000 computer, and thus
bootstrapped."
