Yale and Princeton have both announced substantial salary increases for their faculty members, beginning with the academic year 1955-1956.

Less than a day after Yale had reported it would increase all faculty salaries by ten to 12 1/2 percent, President Harold C. Dodds said yesterday that Princeton will grant $1,000 more per year to all its 215 full and associate professors.

In Cambridge, McGeorge Bundy, Dean of Harvard's Faculty of Arts and Sciences, had no comment upon the surprise move by the other two Big Three institutions.

There seems little chance that Harvard will follow these announcements with a salary increase of its own. The University granted a $1,000 pay rise to all full and associate professors in November, 1951, and has made gradual adjustments upward since then.

Even after increases are granted at Yale and Princeton the present median pay for a professor at the University will be $2,000 ahead of the Yale median, and even more ahead of Princeton.

The only area in which Yale will equal or surpass Harvard will be in paying some instructors as much as $4,200. At present, Harvard pays all instructors $4,000 per year.

Yale said it would pay for the estimated $600,000 boost with university-wide tuition raises. For undergraduates, this increase will be $200 per year, bringing an undergraduate's total bill to $1,800.

Dodds said Princeton expected to pay for the $220,000 increase with money from its annual Alumni Giving Campaign. The New Jersey institution has raised its goal from last year's $653,800 to $1 million for 1954-55.

"We are taking the step in the face of extraordinary financial pressure brought on by rising costs and an income which has risen at a much slower rate," Dodds stated. "Our faculty is our greatest asset and its members must not be asked to shoulder the whole burden."
