Author is John Stewart Denker. Nice to have this site as the MIT courses based on this back in the day (example: http://web.mit.edu/13.021/13021_2003/Lifting%20surfaces/lect...) are pointing to a defunk site. Fantastic content, thanks for the submission!
Wow, this is so much more detailed than I expected. It covers the "main" explanation, and lots of special cases based on a custom airflow simulator. Very cool.
