I couldn't possibly describe every bad teacher I've had without going over my modem time allotment. But one who sticks out in my mind because he is the worst instructor I've ever had in college is Glen Langdon, who tried to teach me about data compression last Spring. What made him horrible was his complete disconnection with the students. He is a real genius who has made many significant contributions to the field, but he couldn't teach Spock how to play "52 pick-up". The material was extremely difficult. All of the students were lost. He didn't care. Langdon just plodded on with his incomprehensible lectures despite the groans and snores from the students. I was able to read some of his evaluations for this course from previous years, and they unanimously pointed out the same problems with his lecture style. He didn't seem to know (or care) why he was standing at the front of a classroom with chalk marks on his back.

I can think of a couple other UCSC Computer Science professors who, while I often found the content of their lectures very interesting, their style left much to be desired. David Huffman (who invented "Huffman Code", the compression algorithm used in your modem) was once asked by a fellow student of mine if the professor could slow down every once in a while so that he could catch up on his notes, to which Huffman replied, "No." And Prof. Ira Pohl, who is a world-famous authority on programming languages, has a monotone voice that could make even the most contextually interesting lecture counteract four cups of espresso.
