This is kind of interesting.

  As I understand it. the EDSAC (the first or second, depending on how you 
  counted, stored-program machine in production service) had an 
  assembler/bootstrap (modern terminology, or course) program wired into a 
  bank of uniselectors as the 'initial orders'.  This allowed for 
  single-character instruction mnemonics and decimal storage addresses. 'A' 
  for 'add' seems clear enough to me, but 'V' for multiply-and-add is less so. 
  So, we apparently had assemblers from more-or-less the very beginning.
