My love for assembly language made me check up the history when the first non-machinecode programming happened. I was curious mostly about whether I would find assembly languages before all those "Shortcode" languages (which were really some kind of macros or libraries, and maybe you could even call some intermediate languages. Some ideas of "higher" languages had been around for some years but never implemented at this point, and of course this was well before true high-level programming languages such as FORTRAN was invented.

She created it way back in 1947. The first computer Baby in UK and all revisions around it had some kind of assembler around that same time. Either to boot and link code symbolically more easily or full-blown assemblers.

Mmh, I wonder what this differs to Kathleen Booth's work in 1947.

I looked into it and there was a lot of "happy accidents" in a lot of sources.

Kateryna Yushchenko started programming using the first European computer known to the public at that point, which must have been nothing else but 1950-1955. The "assembler" was "Address programming language" which invented the concept of pointers. She was first with coming up with the idea of pointers but not the first assembler.

Kathleen Booth being part of the building team for the A.R.C. computer (made out of 700 switches). This was indeed 1946-1947. She was well before Wheeler and Kateryna!

This is how it looked:
