Cornell’s motto
When abbreviating Ezra Cornell’s statement about founding the university it can be used as a complete statement:
"I would found an institution where any person can find instruction in any study."
or in an abbreviated form, which should be punctuated exactly as shown:
"... any person ... any study."
Foremost Benefactor
This term refers to a particular recognition bestowed by Cornell on its most generous supporters. It should be capitalized.
