We had a milkman when I was a kid, circa 40 years ago. We had a refrigerator, but it was still very convenient to get fresh milk delivered every day or two. I think milkmen were killed off not just by the widespread use of refrigeration technology, but also by the rising cost of labor.
Before suitable refrigeration and preservation techniques were available, milk had to be delivered daily, or else it would spoil. This was the daily job of the milkman.
