I guess this is on topic given the "student" in student athlete emphasis given at Northwestern. Northwestern has been among the schools where one can attend a class in which the textbook was authored by the professor.
This point came to mind as I was sorting through some of my old textbooks to include one written by Northwestern Professor Robert C. King as pictured below. (Dr. King taught at NU from 1956 until he retired in 2000. I was saddened to learn he just passed away last year.)
Others who come to mind? (Another I recall was Fred Basolo who taught Chemistry and others in the Sociology Department such as Bernard Beck, Charles Moskos, and Raymond Mack who used papers they had published.)
Going back and reading the poem that prefaced the work gave cause for reflection. As suggested by the poem written decades before Dr. King's passing, he lives on through his own children.
Edited to add: Here is some additional info about Professor King from a tribute that was posted last year at the time of his passing:
"We, as former students, remember Bob’s lab as a hub of exciting research and cheerfulness. Bob was always the first to arrive for work. Long before even the earliest risers amongst us entered the lab, he would have been at his desk for an hour or more, and one would open the lab door to the smell of freshly-brewed coffee, with the sound of Bach, Beethoven, or Stravinsky in the background. There was an ethnically diverse population of students and research associates, and his children were frequent visitors. There were parties to celebrate publication of papers and funding of grants. Bob loved to travel, presenting papers and spending sabbaticals abroad. It was in Korea that he met his future wife and loving companion, Suja."
