Let's not forget the ego factor. In business we worry about the Benjamins. Short of founding a company, there aren't too many big shots who go down in the annals of history. Even then, does anyone remember who Mr Proctor or Mr Gamble were?
In academia, every building is named after someone who did something for the university. Every building has a name. So do scholarships, professorships, colleges. Even wings of buildings. I bet somewhere there's a crapper named after someone (well.. besides
Thomas Crapper).
If you take your university to the promised land (say, UBuff to
THE State University of New York at Buffalo), you're gettin' your name slapped on something. Every President wants that. Alden, Ping, Baker, etc etc. I think Glidden even got his name on N700U, the Glidden Memorial King Air. Books, gym rats, freshmen who haven't discovered beer yet, or 1700 horsepower in twin turbine engines... who's laughing now?
