Sorry if I missed it, how long did this take?
I don't think I said, Anniem. Just under four years. It would have been 1 1/2-2 if I had been able to stay with my original advisor. I had completed my language exam (irrelevant to my area) and my comprehensives just prior to starting the writing stage. They were three 20-page documented footnoted papers on assigned topics in a single 10-day period. That was when I bought my very first computer, an Epson QX-10, a CPM (not DOS) based lovely computer with a green screen and an astounding enormous 1K hard drives with two 5 1/2" floppy drives. Amazing!
P.S. I never understood the value of making students do those three intensive papers in such a short time. What did that prove? You could do speed-paper writing? Oh well, it was what it was.
