russell... I would perhaps nominate bubble sort above quicksort...for us old timers, it was easy to understand, code, and install in our programs where ever we need a sort... bubble sort I would argue first brought sorting to our discipline.
Early in my career I implemented a cross reference function using bubble sort and was ridiculed by a Real Computer Scientist. I opted for quick sort, because I wasnt going to expose myself to that here. :-)
