David Montgomery passed away this past month. I took three classes from him as an undergraduate: two on the history of the Middle East, and a senior seminar in history.
I learned a number of things from him. One of the things I learned from him is that one cannot properly do a history of a movement (political, religious, whatever) without knowing something about the actual people involved. This can present a number of difficulties when dealing with ancient history, but is also a problem in modern society.
I regret not taking his class on the Turkish language the one time I had a chance, but that may not have been productive at the time. I grew to appreciate his level-headed approach.
Another thing I learned from Professor Montgomery was a comment he made about the abilities of undergraduates. He said that when he first started teaching that students had no problem taking in class essay tests and that they could easily write ten pages in the class hour. He said that sometime in the seventies, they suddenly stopped being able to do that. One of the older professors I had still did that. He expected students to write five one pages essays in an hour. That was our test.
I remember meeting Professor Montgomery almost twenty years ago. He had just retired. He told me that he was forced to retire because the department chair wanted to hire someone young who would be cheaper. Ironically, after almost twenty years the history department at BYU has still not found a permanent replacement for Professor Montgomery. His presence will be missed.
