I am really curious to know what some of these people already mentioned are famous for (off to google, I guess).
In higher education administration:
Derek Bok (president of Harvard for like a million years) and William Bowen (president of Princeton for like a million years and currently at the Mellon Foundation): I am counting them as one person because they are partners in crime, so to speak. Known for pushing policy issues, also a focus on opening up access to higher education, and particularly top-tier higher ed, to a wider demographic.
Johnnetta Cole: Another college president, advocate for HBCUs, and women’s issues in higher ed.
David Baltimore: Really he is a scientist (they gave him a prize and everything), but also well-known within the field for his work in administration for higher level (doc and post-doc) science research policy and education. Also somewhat notorious for being involved with a high-profile academic misconduct case, so he is also a cautionary tale.
Because this is a big area, I’m using my last two choices for my own slice of the administration pie, which focuses on students (as opposed to say, research or funding)…
Patrick Terenzini: Professor and researcher on measuring student development, admissions, services, currently at Penn State. My unscientific guess is that Terenzini is the most frequently cited scholar in academic papers on this aspect of education. Even though much of his own research is pretty old now, it’s a big part of the foundation.
Larry Moneta: Another student services person, big advocate for incorporating cutting edge technology into all aspects of student services delivery. Unfortunately, he has also been in the mainstream news recently as he is currently heading up Student Affairs at Duke.
These are all people currently active in the field. I would have to think more about historical people.
