More people listed in "Who's Who in America" have attended Harvard than any other university, the publisher's statistics recently indicated. Yale, Columbia, Cornell, and Penn follow to give the Ivy League a clean sweep of the first five schools.

These figures substantiate the finding that over 60 percent of the college graduates listed in "Who's Who" went to independent institutions rather than large, tax-supported, state universities. In all, 90 percent of those included have attended college.

On a proportional basis, the number of alumni in "Who's Who" as related to the colleges' current enrollment, Princeton gains the top spot. Harvard and Yale fall to sixth and seventh on this "ratio basis," behind Williams, Amherst, Wesleyan, and Haverford.

The publisher of "Who's Who," Wheeler Sammons, Jr., attributes this to the fact that "men and women seem to learn how to live especially well at small institutions.'
