So I am trying to get in touch with a semi retired professor who only teaches classes in the summer at my university. I had a class with him last summer and he was nice enough to write me a LOR. I didn't get accepted last cycle so I emailed him about a month ago and have yet to hear anything. I've checked the course registration and he is scheduled to be teaching the second summer session, but that doesn't begin until the last week of June. I was wondering if I should contact his wife via email who is a full time professor at the same university and much more likely to answer an email. I just don't want to seem like I'm harrassing him but if he doesn't still have my LOR, I really need to move on to another professor. Thoughts? Thanks!
